The Polaris Vac-Sweep 165 is the best in-ground automatic pool cleaner for both vinyl and fiberglass surfaces. The Polaris 165 operates with the pump and filtration systems normally found with fiberglass or vinyl surfaces and installs in just minutes. This pressure cleaner is powered by the pressure of clean water returning to the pool, the Polaris 165 uses a patented jet sweep assembly that blows water against the pool wall to loosen debris in hard -to-reach places even if the pool has an uneven bottom. Its easy-to-remove filter bag captures debris before it reaches your pump basket or filter. Please scroll down to see the full list of parts and accessories for this cleaner.
