Polaris® Vac-Sweep 6-120-00 165 Pressure Side Pool Cleaner with 32' Hose is automatic and suited for vinyl or fiberglass surfaces. This cleaner operates with the pump and filtration. Powered by the pressure of clean water returning to the pool, the 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.
