This suction-side automatic pool cleaner connects to your existing pool pump's suction line—no electricity, no batteries, no separate cleaner pump. The vacuum runs whenever your pump runs, quietly cleaning while you're away or asleep; pool pump of at least 1.5 hp / 1100 W required for optimal suction. Included 12-hose kit provides 40 ft total length, sized for large 20 x 40 ft in-ground and above-ground pools (common rectangular family-pool size) where a 30 ft cleaner leaves far corners uncleaned. Tight hose connections prevent suction-loss leaks; soaking both hose ends in water before install makes them flexible for easier seating. The gear-driven drive mechanism runs quietly, unlike cam-and-spring cleaners that clack across a tile floor—cleans without disturbing a family poolside. Large rubber tires boost climbing ability without marks. Compatible with shotcrete, tile, vinyl, and fiberglass surfaces; moves along floor and climbs walls without sticking at the waterline. Does not clean stairs or handle large leaves (use pole-net). Movable skirt adapts suction to uneven surfaces; included flow regulator tunes suction for fine debris. Hose 39.4 x phi 1.8 in / 1000 x phi 46 mm; product 11.8 x 7.9 x 7.9 in / 300 x 200 x 200 mm; net 13.7 lbs / 6.2 kg; pump req ≥1100 W; in-ground + above-ground; model R5.
