The Polaris Vac-Sweep 360 features advanced technology that cleans without a separate booster pump. The Polaris 360 vacuums, sweeps, and scrubs the bottom and walls of any size or shape pool. The in-line backup 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. The unique filter bag removes debris before it reaches your pump basket or filter, prolonging the life of your filtration system.
