Our take on the Polaris 3900 Sport Pressure Side Automatic Pool Cleaner

The Polaris 3900 Sport is a pressure-side automatic cleaner for in-ground pools. It runs off a dedicated pressure line and a separate booster pump, driving an all-wheel PosiDrive system with a stainless-steel chain and WideTrax tires to sweep floors, walls and gradual slopes. Its dual-chamber zippered SuperBag holds more debris than a single bag, and it comes with 31 feet of hose, floats and swivels. It suits owners with a booster pump and a pool around 15 by 30 feet; against suction-side cleaners it scrubs walls and needs no separate vacuum, but it depends on that extra pump and a dedicated line.
