Polaris Vac-Sweep 65 6-130-00 Pressure Side Automatic Pool Cleaner for Above Ground Vinyl Pools Suitable for all aboveground pools up to 5-feet deep. Installs easily in minutes. Powered by the pressure of clean water returning to your pool, leaving both the filter and skimmer free to eliminate contaminants. Operates with pumps and filtration systems normally found on aboveground pools and vacuums the bottom and sweeps the sides in three hours or less. Patented jet sweep assembly blows water against the pool wall to loosen debris in hard-to-reach places and then sweeps it into an easy-to-remove filter bag. Unique filter bag removes debris, including larger items like twigs and pebbles before it reaches your pump, prolonging the life of your filtration system.
