Robotic Pool Cleaner Comparison: Our Top 20

One of the most popular items we sell here at PoolSupplyWorld are Robotic Pool Cleaners. Who wouldn’t want a machine powered robot to take care of all the cleaning chores we don’t want to do ourselves?

We carry over 50 different robotic cleaner models which makes deciding on which robotic pool cleaner to buy a grueling and difficult task. However, to help our customers with this problem we’ve gathered a list of our bestselling robotic pool cleaners and have broken them down by their specifications, features, warranty, and most importantly price.

Which robotic pool cleaners do we recommend to our customers?

While most robotic cleaners upgrades should be a huge improvement over traditional suction-side / pressure-side cleaners there are a few cleaners that really stand out from the rest which we have listed right below.

    Can you explain the difference between the Polaris 9100 sport and the Polaris p91?

  • Michele

    Of the 3 brands, which do you think is more reliable? The Dolphin Deluxe 4, the Polaris 9300 or the comparable Aquabot? Should I be concerned with a warranty that is only 1 year? Thank you.

    • PoolSupplyWorld

      Hi Michele, All three of the cleaners you listed are good, reliable cleaners. Tell us a bit about your pool and we can help determine which is best based on that. What size is your pool? Is it vinyl lined, gunite, or fiberglass? Do you have mostly leaves and large debris or sand, silt and small debris?

  • Glenn Reisman

    It would be useful to add the following information: 1 the weight of each unit, and 2 whether every warranty is full or prorated

    • PoolSupplyWorld

      Hi Glenn, The 9100 weighs about 13 pounds dry and the 9300, 9300xi and 9400 are all about 25 pounds dry. None of the warranties are prorated. Let us know if you have any other questions!

  • Rene

    Hi, I have a 35×15, 17000 gallon, inground pool, with 3 steps in the shallow end. The pool is plaster. Our booster pump just died so now I’m looking for a robotic cleaner. I don’t have lot of leaves in the pool, mainly small debris. I’d like something that also cleans the walls. I’ve been looking at the Polaris P9300 and the Dolphin Diagnostic advantage (which appears to be discontinued). Do you have any recommendations? Thanks.

    • PoolSupplyWorld

      Hi Rene, Someone from our customer support team will be contacting you to assist shortly. Thanks!

  • Eliser Lebin

    I have a pool that is 30×15 inground and the surface is gunite/concrete. At the shallow end there are three steps.Right now I am using the Kreepy Krauly cleaner and t is not doing the job as expected. I have this unit for 7 years and I want a cleaner that does not use the suction return line for reasons that it is costly on electriciy when in use. I am looking into a robotic cleaner so I can use it probably twice a week rather than every day. Do you have any recommendations?

  • Christie

    Hi! We have a gunite 21 x 40 pool with stairs and benches. I am looking for the best robotic cleaner for our type of pool. I was recommended by the pool installer the Polaris 9300, but have heard bad reviews of it falling over backwards and doing the same spots over and over because of its random pattern of cleaning. I am looking at purchasing a Dolphin Premier with the smart nav and just would like advise on if that would be a good choice, or what would be a better idea? We get all types of debris, leaves to small particles. Thanks for the help!!

    • http://www.poolsupplyworld.com/ Roy Steves (PoolSupplyWorld)

      Hi Christie,

      Whether you consider the Polaris or the Dolphin, both have the same solution I’d recommend for a very tricky pool–a remote control option. In the Polaris case, that would be the F9300xi, and the Dolphin’s is the DX5 Plus (SKU: 9999381DX5). There’s a slight difference in their propulsion–the F9300xi has a rear jet, whereas the DX5 Plus has a top jet. This will sometimes result in the F9300xi launching off of ledges, but it also can sometimes climb up and hop over them to begin with. The Dolphin sticks to walls and surfaces more aggressively, so it just needs to get over the lip of the bench, and it’ll do well from there.

      With a remote on both units, and a similar price, I would tend to follow the reviews–where the DX5 Plus is well ahead. Stairs and benches can be a challenge for any cleaner, but with the remote, the DX5 Plus should leave you with the least manual brushing possible.

  • Dennis

    I have an Aquabot turbo T2 that is three years old. Loved it. The drive motor has gone bad and I need to either repair it or replace it. The replacement cost is very high. The pool is 25,000 gallons, inground fiberglass and I like that no hoses are needed with an electric robot. Is there a less expensive alternative to the turbo, without sacrificing results? Or do I just buy another one?
    Mostly I have dust, pine needles and small debris.

    • http://www.poolsupplyworld.com/ Roy Steves (PoolSupplyWorld)

      I have a couple recommendations. If you’re looking for an alternative with a similar cleaner style, the Dolphin DX5 is certainly worth considering (or the DX5 Plus if you want a remote, etc.). It’s currently less expensive than the T2.

      Another possibility is the Aquabot Hydro EXL (http://www.poolsupplyworld.com/Aquabot-Hydro-EXL-Robotic-Pool-Cleaner-with-Eco-Friendly-Energy-Saving-Technology/AHYDROEXL.htm ). It’s aimed for small to medium pools, and is a new cleaner from Aquabot. If you were happy with the T2, the DX5 is the safer bet, as your pool likes that style of cleaner, but the Hydro is well liked, and certainly less expensive.

      If you want to discuss the options, jump on to the main PoolSupplyWorld site, and hit us up on LiveChat! We’d be happy to discuss what the best option might be for your pool’s specific needs.

  • Steve

    i recently installed a 15000 gallon, 16×32 in-ground pool with sprayed concrete walls. Looking for a reliable, effective robot cleaner. Any recommendations?

    • Dylan (PoolSupplyWorld)

      What kind of debris do you typically get in the pool? And were you interested in a remote control for the cleaner? My personal favorite for a robotic cleaner will be the Water Tech Blue Diamond. This cleaner has a few aspects that I particularly like. It is able to filter down to 3-5 microns ensuring it collects sand and dirt, comes with a 60′ floating swivel cord to prevent tangling, and has a 4 year manufacturer warranty.

      If I had to choose a second, I would pick the Dolphin Dynamic DX5. This cleaner is a great option as well and has proven capable of navigating a pool well and climbing just about most walls. Feel free to give any of our sales reps a call at 800-772-0467 and run your pool setup by them to get another opinion. Thanks!

      • Steve

        The debris would include leaves, dirt and bugs. The pool will be lightly used during most periods given the location and because it is on a vacation property.

        • Dylan (PoolSupplyWorld)

          For the dirt I would like the Water Tech Blue Diamond the best. Like I mentioned, it filters down to about 3-5 microns which is as fine as it gets. The Dolphin DX5 is in the 50 micron range and the Polaris robotics are in the 100 micron range.

  • rose bambach

    We recently became the proud first time owners of a home with an inground pool. We have been looking for a study, reliable and effective robotic vac. We are on a tight budget so price is an issue… We can’t afford to go into the thousands for a vac. Algae, dirt worms and thin sand are the primary culprits of debris in our pool.
    We have a 17′x24′ 12,000 gallon vinyl liner pool with a steep 2′ incline at the bottom.
    Any recommendations?

    • Dylan (PoolSupplyWorld)

      The largest worry that jumps out to me is going to be that fine debris that you currently get in your pool, the sand and dirt. Most of the low priced cleaners do not have a filter that is going to filter to a fine enough level to collect and hold that sand. The cleaner that will perform the best in your pool would be the Water Tech Blue Diamond (BLD03). While this cleaner is currently $873.99 it would perform the best in your pool and ensure that all of the debris is collected.

      Now if this cleaner is a bit out of your price range then my next suggestion would be the SmartPool 7i Robotic Cleaner. This is currently available at $470.99 with a $50 rebate and will do a good job of navigation your pool. It does not have quite the same filter capability so it won’t collect all of the sand and small debris in your pool.

      Feel free to give us a call at 800-772-0467 to discuss any other cleaners, we are always happy to help you find the best fit for your pool. Thanks!

  • Shirley

    We have an in-ground vinyl L shaped pool, 40′ x 26′ on the longest side, with 4′ steps on the 26′ side. It is 8′ at its deepest and 4′ in the shallow end. We have had a Polaris 360 with a booster pump and the pump has gone out. We have mostly dirt and insects in the pool season, and lots of leaves when opening. This year we had also had a lot of dead algae to vacuum out. I would like something to handle the fine debris, plus could help at pool start-up after the worst of the leaves have been cleaned out. What do you recommend?

    • Dylan (PoolSupplyWorld)

      If you are really looking to handle the fine debris a great option would be the Water Tech Blue Diamond (BLD03). This cleaner has a micron level down to 5 microns, which is as fine as you can get. The cleaner includes a swivel cord to prevent tangling, a length 4 year manufacturer warranty, and the capability of filtering the finds sand and dirt.

      If you have any other cleaners you had questions about then certainly feel free to give us a call at 800-772-0467. Have a good day!

  • robin milward

    I have a new 12 x 20 rectangular unground tile infinity (long side) 4.5 ft deep pool with semi circular corner steps at each end on one side.Which mid price robot would you suggest.Year round use in the south,some leaves in Fall.I am used to leaving a Kreepy to run all nite,yet most robots run only an hour or so.Doesn’t that mean they have to be continuously re started while pool is half cleaned?

    • http://www.poolsupplyworld.com/ Daniel Henson(PoolSupplyWorld)

      Hi, Robin! Thank you for the great question. The Dolphin Dynamic DX5 Plus or the Polaris 9300 series are great options to consider. There’s a handful of robotics that have 2, 3 or even programmable cleaning cycles. This allows you to customize the cleaning time frame and avoid restarting the cleaning cycle, if the pool isn’t completely tidy.

  • Ajeeb Peter

    I Do have small pool and I would like to get cleaned periodically. After few research I found Dolphin Nautilus has good reviews but it doesn’t comes with caddy and just 1 year warranty. I see another option Dolphin Triton with caddy and 2 years warranty with a price difference of $200. In this case what would you suggest?? Triton has any other benefits ?? how is the performance?

    or any other better suggestion below $800.??

    • Dylan (PoolSupplyWorld)

      Neither the Dolphin Nautilus or the Dolphin Triton are models that we have available on our website. But we do have a very comparable cleaner in the Dolphin Dynamic DX5 at the following link:


      The Dolphin Dynamic DX5 will be just about identical to the Dolphin Triton that you had been previously looking at. Many of the features will be the same as the DX5 has a two year warranty, floating swivel cord, 50-70 micron filtration, and the same navigational capability. I would suggest giving one of our sales reps a call at 800-772-0467 to find the best fit for your pool.

  • Dylan (PoolSupplyWorld)

    Neither the Dolphin Triton or Dolphin Nautilus are cleaners that are offered on our website, but we would have a comparable option for you. The Dolphin Dynamic DX5 is a great option that we have available at the following link:


    This will be virtually identical to the Nautilus as it shares many of the same features. It comes with a two year warranty, identical filtration bag, swivel cord, and many other features. If you have further questions about the cleaners available feel free to give us a call directly at 800-772-0467, thanks!

  • Pj Jones

    I am trying to decide between the Dolphin DX6, Polaris 93, or 94. My pool is 27 X 50 and gunite. In the fall I get a lot of leaves and pine needles. I am not as concerned with the ledges or stairs, those I can brush myself. I am looking for the best unit that will keep up and last the longest….. Help!!

    • http://www.poolsupplyworld.com/ Roy Steves (PoolSupplyWorld)

      From the Polaris and Dolphin families, the DX5 Plus ( http://www.poolsupplyworld.com/Dolphin-Dynamic-DX5-Plus-Robotic-Automatic-Pool-Cleaner/9999381DX5.htm ) is the highest rated, and is recommended for pools as large as yours. All of the cleaners you are considering would do well with that type of debris. The Polaris cleaners will be slightly easier to empty, using canisters rather than filter bags, but the Dolphins will filter finer silt than the stock Polaris canisters.

      I think you’d be very happy with the quality and price on the Dolphin DX5 Plus.

  • Pj Jones

    What about the single motor vs double or two wheel drive vs 4 wheel drive

    • http://www.poolsupplyworld.com/ Roy Steves (PoolSupplyWorld)

      Well, I’d recommend against the Polaris 9300 because it has a shorter cable than the 9400, so it might not handle your pool as well. The 9400 has two advantages over the 9300: a longer cable appropriate for your pool, and four wheel drive. The four wheel drive is more agile, and better for steps, but it sounds like you’re not as worried about that. The Dolphin DX5 Plus has the long cable as well, in addition to good agility due to the dual motors and scrubbers, and they’re about the same price, so it’s a close comparison.

      At that point, the most common complaints against the standard DX5 is that it can miss spots–but the DX5 Plus has a remote, so those concerns are almost entirely addressed. The Polaris 9300xi also has a remote, and the longer cable, but has had a bit of a troubled past with durability (although I believe those issues have all been addressed by the manufacturer nowadays). The 9400 doesn’t have a remote, but reviews indicate that its automated cycles are pretty thorough.

      So, with the 9400 and the DX5 Plus being almost exactly the same price, I’d probably lean toward the one with better reviews and a remote.

  • Bradley Evans

    Hi Bre,
    I live in Australia and we have a lot of gum trees that drop into our pool quite often. I have a standard kreepy krauly (like the ones here http://www.kreepykraulyparts.net) Just wondering what cleaner you would recommend to do the job?


    • Bre

      Hi Brad! Since you do have a lot of gum trees in the area, suction side pool cleaners are going to have a little trouble picking up their long leaves. Even with the use of a leaf canister, the leaves are likely to get caught and clog the cleaners throat. I would recommend you go with a Robotic Pool Cleaner like the Dolphin DX5. The DX5 is a great pool cleaner and will have an easy time picking up the larger leaves of the gum trees.

  • Tasha Ostapczuk

    Hi guys,
    I am in the market for one of these guys but my great confusion comes in here- my in ground pool is octagon shaped. So there are a lot of corners, turns at the walls and I would really like a robot that can do the whole pool not just the bottom as I am a single woman in the household and a traditional vacuum is very tedious. I live in upstate NY. Good mix of rain, heat/sun and a maple tree above my pool. Something for algae, and leaves would be great! But… it is the shape I need to get over….

    • Dylan (PoolSupplyWorld)

      Hello Tasha,
      It does sound as if the Dolphin Dynamic DX5 would be a great robotic cleaner option for you. The DX5 does a great job navigating pool floors and pool walls all the way up to the tile line. If you even wanted to upgrade to the DX5 Plus, this Plus model will come with a remote control too allow for even greater control over the movements of the cleaner. This may be a good feature to have as it will help to prevent any possible hangups along your pool corners. Feel free to give us a call directly at 800-772-0467 if you did have further questions about this cleaner or any others.


  • Linda Treffinger

    My Dolpjin Diagnostic 2001 is 11 years old. It keeps shutting off after an hour. I know it needs service but I am hesitant to spend money on an 11 year old unit. I was looking into the Smartpool Direct. My pool is 19x 32 kidney with vinyl liner and salt chlorination. What do you recommend?

    • http://www.poolsupplyworld.com/ Daniel Henson(PoolSupplyWorld)

      Hello, Linda. I understand your concern for questioning whether you should repair or replace. The main factor would be to determine what is actually wrong with the cleaner. If it’s a simple, inexpensive fix, it might be just worth repairing. However, if the cleaner is truly on it’s last leg, you may fix this one issue and simply find many more to come shortly thereafter. I would recommend opening the cleaner and checking the insides for any obstructions in the drive track. However, do not open the electronic compartments as these are sealed to prevent water leaking in and once opened, pose a challenge to reseal. Also, you may want to check power supply with a multimeter.

      The Smartpool Direct Command is no longer offered on our site, but a suitable replacement would be the Smartpool 9i – http://www.poolsupplyworld.com/SmartPool-9i-Scrubbing-Robotic-Pool-Cleaner/PT9i.htm. The siginificant differences is the 9i doesn’t include a remote.

      If you’re looking for a robotic that includes a remote, and you were happy with your Dolphin, I would recommend the Dolphin DX5 Plus – http://www.poolsupplyworld.com/Dolphin-Dynamic-DX5-Plus-Robotic-Automatic-Pool-Cleaner—Includes-Joystick-Remote/9999381DX5.htm.

      I hope this helps. Please let us know if we may be of any further assistance!

  • Carol Warehime Fearns

    We have an above ground 28 ft round doughboy, vinyl liner with a deep end. We get a lot of green algae and got really tired of cleaning the pool. What robotic system would you recommend for cleaning the deep end pool liner

  • George

    24 round above ground. Want a vacuum type that will catch the really small dead algea that is so hard to filter out. No review points at a superior model. Tigershark? Aquabot?
    What say ye?
    George in Kansas

    • http://www.poolsupplyworld.com/ Daniel Henson(PoolSupplyWorld)

      Hello George. Most algae found in pools is typically between 8-16 microns. Any of the cleaners that filter particles below that size would suffice. Both of the cleaners you mentioned will have similar performance as their design is quite common. Personally, I would recommend the Aquavac Tigershark.

      Please let us know if you have any other questions!

  • Cory stepanek

    Hi, we just moved to a home with a rectangular pool 20×40 (3 feet to 8 feet deep) and are looking into a pool cleaner best for our Palm Springs home.

    What would be your top 3 picks for our pool?



    • Dylan (PoolSupplyWorld)

      My three top cleaners to select from will include the Dolphin DX5, the Water Tech Blue Diamond, and the Kreepy Krauly Prowler 820. The reasons I would select one of three is due to a variety of factors. Things to take into consideration are the micron filtration rate, the warranty length, cord length, price, manufacturer reputation, and a number of other smaller aspects. There will be more expensive models available that will come with additional features such as a remote control. But if you are looking for the top robotic cleaners with an affordable price range, then the three I mentioned are ideal.

      We do have a blog that would be related towards pool maintenance and some of the basics you will need to keep in mind.


      If you had any additional questions feel free to leave another comment, or reach us at 800-772-0467. Have a good day!

  • Lisa

    Hi we just had a 20×40 inground rectangular pool with two drains in the 8 ft installed this summer. What robotic pool cleaner would you recommend that does not get stuck on the bottom drains? Thanks!

    • Dylan (PoolSupplyWorld)

      Thank you for visiting our blog! I did forward your information over to one of my sales representatives to have them send a quote over your way. Both the Dolphin DX5 and the Water Tech Blue Diamond are excellent choices, and two of the top robotic options in my opinion.

  • mark

    I’d like to make my pool more energy efficient by using a robot vs a pool sweep (I have to increase the RPM’s in my pool pump by 1000 to get the sweep to run, which greatly increases the pump’s energy cost). My pool is a 7.5′x35′ lap pool, with an (additional) 1′ wide (18″ deep) shelf running along one side and a 5′ radius tanning/Shamu shelf (6″ deep) at one end, off of the shelf. What would be your robotic cleaner recommendation? I haven’t been able to figure out what the differences are — they all get great reviews (when they work). They all seem to have similar negative reviews, too — for some people they wear out too quickly and shipping isn’t included in the warranties…

    • Dylan (PoolSupplyWorld)

      Great questions you have there, I let one of our sales rep know about your questions and he will be contacting you directly via email. The ledges and tanning shelf are tricky features and honestly it is going to be hard to guarantee any cleaner being able to clean them consistently. When it comes to tricky features such as those, we often like to recommend a robotic cleaner with a remote control as the motors generally are stronger and can be controlled with the remote in case a spot is missed.

      Personal favorites of mine will be the Water Tech Blue Diamond RC, the Dolphin DX5 Plus, and Kreepy Krauly Prowler 830. Feel free to work directly with the sales rep, Alex, to find the best fit for your pool. Let me know if I can be of assistance as well. Thanks!

      • mark

        Can you please have Alex resend the information. After swimming a few times (California is warm this winter), I think we really do need a robot. Can you also explain the differences between the DX5 and the Premier Dolphin models? They appear to be similar in price (sales with remotes around $1100), but I can’t find the full specifics on the DX5 Plus. The Premier says it learns the pool, with generally a 2.5 hr cleaning cycle, 65 ft cable, while the DX5 has choices of 2, 3, 4 hours. The Premier has 2 micron and 4500 gal/hr filtration, while the DX5 advertises “ultra fine’ and 4,233/hour filtration. The Premier uses 180 watts and is 22 lbs, while the DX5 is 24.25 lbs (can’t find it’s wattage). Both have 3 year warranties and clean the waterline. I can’t seem to find any comparisons between the two. Thanks!

  • Robert Branstrator

    Variety of option to choose from…my pool will be much cleaner now.

  • mcmoyer

    my most recent pool robot, an Aquabot Pool Rover, Jr. died last season and I was thinking of replacing it with a SmartPool 4i. However, it looks like the 4i won’t filter out algae as good as the Aquabot did — I’m assuming that the filter bag for the 4i will be about the same filter rating as the 7i. I get a lot of algae blooms in Texas and the aquabot did a good job of keeping it out of my filter. Is that a fair assessment?

    • Dylan (PoolSupplyWorld)

      The Aquabot Pool Rover Jr. does have a filtration bag on it that filters down to smaller microns than the SmartPool 4i or 7i would be capable of doing. For handling small debris, such as algae, the Aquabot Pool Rover Jr. would be the better suited model. Where the SmartPool versions have an advantage is in the climbing ability, the durability, and the filter size. If you were dealing with larger debris such as leaves, then the SmartPool cleaners would be the better choice. If you have further questions just let me know!

  • Cassy

    I am in planning stages of having an ground pool installed. Buttonwood trees dot my yard and I hear they are a disaster on pool floors. What robot cleaner can handle these leaves before they stain my pool?

    • Dylan (PoolSupplyWorld)

      Hi Cassy,

      There are a number of good robotic cleaner options that would be suitable for your pool. Do you get much small debris? Or is it mainly just the leaves? A cleaner that would be great for picking up leaves is the Polaris 9300:


      The canister (rather than a bag) inside of this cleaner is really easy to clean and can handle a good amount of leaves before needing to be emptied out. Polaris also offers a few upgraded models that offer a remote control (F9300XI) or 4-wheel drive (F9400). Let me know if you have any further questions about this cleaner, or any others!

  • Cates

    I have a kidney shaped pool with a margarita bench, I am looking for a robot that does a good job of cleaning the sides so I do not have to scrub them with a brush as much, and cleans the bottom too! I also do not want to break my wallet, what do you recommend?

    • Dylan (PoolSupplyWorld)

      A great robotic cleaner for you to consider will be the Dolphin DX5. This cleaner does an excellent job of climbing just about any pool wall, as well as uniformly covering the pool floor. One of the best features of the Dolphin DX5 is it’s affordable price. A high quality robotic cleaner typically falls in the $750-$1100 price range, the DX5 just so happens to be on the less expensive side of things.


      With a swivel cord, two year warranty, and excellent filtration; the Dolphin DX5 is a personal favorite of mine. If you would like to know more about this cleaner, or any others, just let me know!

  • Karen

    In the beginning stages of putting in a pool with a mechanical cover, is there a cleaner that can run while the cover is closed? I’m interested in the Dolphin DX5 due to the steps, ledges and walls of the pool. Thoughts?

    • Dylan (PoolSupplyWorld)

      The Dolphin DX5 is a great option and one that I would recommend to just about any pool owner. The traction from the treads does a good job of climbing over obstacles throughout the pool. The mechanical cover shouldn’t be a big issue with the cleaner, as long as there is room underneath the cover for the cleaner’s cord to move about. If the cover is restricting the movement of the cord, then it will be restricting the movement of the cleaner, and thus your pool doesn’t get cleaned! Also, make sure there’s an edge somewhere along the cover where you will be able to have the cleaner cord running from the power center into the pool.

      Have a nice evening!

  • Molly

    Do cleaners work the same in in chlorine and saltwater pools? If not what do recommend for a saltwater pool? Mine is an in ground 30×80 with two rounded corners.

    • Dylan (PoolSupplyWorld)

      Hello Molly,

      I do apologize in the delay in getting back to your question here. Cleaners will work exactly the same in either regular or salt chlorinated pools, there will be no difference to consider. Now a key question will be what cord length for the cleaner do you think you actually need? Your pool is quite large and I would want to know if the cleaner you need has to have 80′ of cord, or would it be possible to go with a shorter cord, such as 15′? To determine what you need, I would decide whereabouts around the pool you are going to place the power center, and then we can decide what cleaner might be the best fit.

      There are a lot of robotic cleaners with cords in the 65′ range. The 80′ range is a bit tougher to come by and would limit the choices we have. Thanks!

  • christine mckenna

    I have an unground 16×32 freeform saltwater system pool. I’m looking for a robotic cleaner that can do the floor, walls, & waterline but also stay in the low 700s. Any reccomendations would be appreciated!

    • Dylan (PoolSupplyWorld)

    I have an indoor 16×32 concrete pool with bromine. I was looking to buy a pool cleaner. just wondering, what would you recommend under a $1000.00.

    • Dylan (PoolSupplyWorld)

      A personal favorite of mine will be the Dolphin DX5 Robotic Cleaner. If you take a look at a few of the other comments I generally like to recommend this cleaner in most situations. It has great pool navigation ability, efficient filtration, and a very affordable price range. The Dolphin DX5 does come with a two year warranty, as well as an included caddy cart for easy transportation and storage.

      If you have any questions about this cleaner, or any others, just let me know and I would be happy to help. Have a good day!

    I live in southern Maine and have a 16 X 32 vinyl ingrown pool. We have corner steps built in. I’m looking to get a robotic cleaner.. Which do you recommend the Polaris 9400 / 9300 XI or the dolphins première? Trees only an issue just before we close it.
    Thank you.

    • Dylan (PoolSupplyWorld)

      For a vinyl surface I do like to recommend a cleaner with treads as I believe it does a better job gripping the surface of the pools, and able to climb walls a bit easier. The Dolphin Premier is something that is not currently available on our website, but I would recommend the Dolphin DX5 Robotic Cleaner as being an excellent option.

    Hi I have an indoor saltwater pool here in ireland and I was wonder which would be the best for algae ..any suggestions ?

  • Barb Green

    Hi, We have a 16×36 fiberglass free form shape pool (Coral Sea 2 by Barrier Reef) that has steps the width of the pool and a ledge and step-outs around the entire pool about 2 feet from the top. Most of our debris is sand/dirt & worms (which I could do without! ha). I have been looking at the robotic cleaners and I see both positive and negative reviews on most of them making it hard to figure out which would be the best fit for our pool. Now that some of the new models have come out, what are your recommendations? Thanks in advance.

      Hello Barb,

      You will probably be seeing mixed reviews due to the fact that each persons experience with a cleaner is different because of their pools. First, I’d assume your largest concern is your steps as this is where most cleaners cannot reach. The good news is most of these robotic cleaners will do a great job of cleaning that up. I would suggest a few to you:

      1.) The Water Tech Blue Diamond – This is a fantastic cleaner. It’s going to clean your walls and floors and filter up to around 2-5 microns. It’s got a short cleaning cycle so it will save you energy, has a smart guidance system, a swivel so the cord won’t get tangled and even comes with a caddy. The only downfall I have seen from this cleaner to date is the coloring, and the price. Though, if you are willing to give it a chance it will do you well!

      Here is the link if you want to check it out – http://www.poolsupplyworld.com/Water-Tech-BLD03-Blue-Diamond-Robotic-Pool-Cleaner/BLD03.htm

      2.) The Polaris 9300/9400 – The biggest difference between these two cleaners is the price, and design. The Polaris 9300 is going to clean up your pool with a filtration system that reaches lower than 100 microns. The cleaning cycle will be a bit longer than the Blue Diamond, around 30 minutes to an hour longer. Do not fret though! This cleaner will also clean your floor, walls, most steps and even up to the waterline. The difference between the 9300 to the 9400 is the more sturdy wheels and 4-wheel drive on the 9400.

      Again, here is the link to our website if you want to check it out – http://www.poolsupplyworld.com/Polaris-9300-Robotic-Pool-Cleaner/F9300.htm
      and the 9400 – http://www.poolsupplyworld.com/Polaris-9400-Sport-Robotic-Automatic-Pool-Cleaner/9400-Sport.htm

    Our 13 year old pool needs a new cleaner. Two possible issues …. we have a beach entry (gentle slope to walk into pool, not a hard edge in that one area) and we have 4 barstools built into the pool (never go to a 5 star resort prior to designing your pool). My guess is that the bar stools (basically a gunite column coming up from the pool bottom with a stone top somewhat below the pool surface) can be avoided. What do you suggest for a robotic cleaner? The built in cleaner used the hose length to avoid the beach entry and luck to keep from getting stuck amoungst the built in bar stools

      Hello Jeff,

      Thanks for checking us out! I would suggest a specific cleaner for you – The Hayward SharkVac XL
      The reason I would do so is because this cleaner comes with an out of water sensor, as well as a beach entry sensor. This allows it to tell when it is actually coming out of the beach entry and turn around. It’s a pretty unique feature for a cleaner, and I could see it working very well for you. It also comes with a 60′ cord, allowing it room to maneuver around those bar stools.

      Here is the link in case you want to check it out on our website – http://www.poolsupplyworld.com/Hayward-RC9740WC-SharkVAC-XL-Robotic-Pool-Cleaner/RC9740WC.htm

    I have a 16×32 inground pool and we’re constantly battling with algae throughout the season. Looking for a robotic cleaner that will handle this as well as smaller debris such as dirt. I have been debating between the Aquabot, Aquabot Jr, and Smartpool 7i as I am on a fairly tight budget. Any recommendations between these cleaners or something else relatively comparable would be greatly appreciated. Thanks in advance.

    • http://PoolSupplyWorld.com/ Robby Stahl – PSW

      Hey Tim,

      Since you said you’re on a tight budget, I would suggest the Smartpool out of those few cleaners. The build quality is going to make it last longer and to beat those pesky small debris you’re going to have a much better time with this cleaner. The unit comes with brushes that help scrub the bottom of your pool while collecting dirt and other debris. It’s also made with a nice large filter bag so if there is a build up of dirt already it’ll have an easy time collecting all of it. I would say for the price, you won’t get better than the Smartpool cleaner. Hope this helps!

    Hi. I have an 83′ by 7′ lap pool (about 5′ deep) that also has a 4″ deep ledge / beach entry running along half of one side. 2 main questions – none of these have cords longer than 60ish feet. If I plug the unit in near the center of the pool it will theoretically be able to reach both ends, will that work? Also, when a robot climbs the wall where the 4″ deep ledge / beach entry is, what will it do? I doubt any of these will clean the ledge area, but I’d be happy if it would just know not to go up there out of the water. Any recommendations on specific robots for my pool? Thanks!

    • http://PoolSupplyWorld.com/ Robby Stahl – PSW

      Hello Matthew,

      With the size of your pool you seem to have the correct concerns. The good news is putting the cleaner near the center of the pool should definitely allow it to reach both ends. The only thing you would want to think about is the farthest ends, since it will have to cross the 7′ to the other end as well as half of the pools size, so around 41′ 1/2. I posted this cleaner before, since there was another blog visitor who also had a beach entry –


      The SharkVAC XL has it’s own sensor system to catch when it is out of water, or traveling out of water, making it perfect for these not too deep edges and beach entries. This should allow it to clean the ledge as well not climb on out of your pool and away.

    I have a 20×40 inground pool in Ohio. We would like a robotic cleaner to clean the pool. We deal with leaves throughout the year and algae. We would need it to clean the entire pool. Which robotic cleaner do think would be the best, (aquabot, polaris, dolphin etc.). Thanks

    • http://PoolSupplyWorld.com/ Whitney (PoolSupplyWorld)

      We have a lot of great pool cleaners that I know you’re going to love. My first instinct when recommending a brand of robotic pool cleaner is Dolphin. All of their models are very high quality and exceptional pool cleaners. They are the biggest in the robotic industry and their Dolphin Dynamic DX5 Plus is one of our top sellers. Another very popular brand is Polaris. They are known best for their pressure side cleaners, but have launch a few great robotic cleaners as well. Their Polaris 9300 xi is also very popular. Both of these models come with remotes that allow for manually steering of the cleaners and caddies for easy mobility to and from the pool. Both of these models are also available without the remotes if that would work better for your needs.

    I am in the market for a new robotic cleaner but I have a couple of concerns. First, I am replacing an old polaris with the upright bag that runs off of the filtration system and I typically just leave it in the pool even when the pool is in use. The hose is a nuisance at times but at least it is in the pool. With a robotic cleaner, I am going to have to have the power supply under an overhang in the pool area and will have to have the cord to the robotic cleaner hanging out of the pool and running across the patio. Do any of you just leave your robotic cleaners in the pool 100% of the time (but unplugged) and then just plug the thing in when you are ready to run a cleaning cycle?

    I want the cleaning power of a robot but I hate having to deal with the electric cord. My wife is a cord nazi as well and she is not going to like the look of that cord hanging over the edge and running along the patio.

    What to do..Decisions, Decisions, Decisions.

    • http://PoolSupplyWorld.com/ Whitney (PoolSupplyWorld)

      Thanks for chatting in! I know that is a concern with many pool owners. With robotic cleaners it is not suggested to leave the cleaner in the pool when it is not in use. The cord will lay across the patio when the cleaner is doing its magic. Many of the robotic cleaners that we carry come with a caddy. This allows you to put the cleaner on the caddy and roll up the cord. This will make storage easy when the cleaner is not in use.

    I have a 20×40 inground pool with multiple trees surrounding it. I also have several “wrinkles” in the bottom of the pool. Currently I am using a kreepy krauly, but it gets stuck on the wrinkles. Do you have a suggestion for a robotic cleaner that can handle my problems?

  • PoolSupplyWorld

    Hi Donna, the Polaris P91 is designed specifically for Leslie Pools and is functionally the same as the Polaris 9100; the only difference is the color. Please let us know if we can be of any further assistance.
