The Polaris Vac-sweep 360 features advanced technology cleaning without the need for a separate booster pump. The Polaris 360 vacuums, sweeps and scrubs the bottom and walls of any size or shape pool. In-line back-up valve automatically frees the 360 if it gets cornered and continues to clean without interruption. Powered by the pressure of clean water returning to your pool, the 360 leaves both the filter and skimmer free to eliminate contaminants. Unique filter bag removes debris before it reaches your pump basket or filter, prolonging the life of your filtration system.
