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.

Owners of pressure-side Polaris cleaners generally report strong wall climbing and good debris pickup, and the 3900 Sport is valued for its all-wheel drive and large bag. Complaints center on the booster pump requirement and hose reach on bigger pools.
The Polaris Vac-Sweep 3900 Sport is a pressure side automatic pool cleaner for in-ground pools. It sweeps and scrubs the floor, walls and gradual slopes, and it works on all pool surface types.
