The Balboa Mighty-Vac is designed as both an external vacuum and in-line blower for in-ground and above-ground pools. Its powerful operation can set in-ground and above-ground vinyl liners without a problem. It also features a winterizing capability that allows it to clear plumbing lines to prevent freezing or clogging. Its yellow, box-like design and steel housing is both portable and sturdy, and weighs 20 pounds for convenient transportation. It requires 120 VAC and draws 13 amps for operation.
