About
**HydroCurve Smart Navigation — Systematic S-Path, Zero Blind Spots**: Powered by the HydroCurve intelligent algorithm, Hydro 4 SE navigates a systematic S-shaped path that methodically covers your pool floor, walls, and waterline—maximizing coverage while eliminating blind spots. This isn't random wandering: the cleaner continuously optimizes its route so every section gets thoroughly cleaned in less time, leaving you more time to actually enjoy the water.
**Patented Waterline Lateral Scrubbing — Erase the Oily Ring**: Most cleaners float right past the scum line—Hydro 4 SE scrubs it away. Its patented waterline lateral movement technology lets the robot glide in stable, prolonged parallel motion along the tile line, increasing waterline coverage while scrubbing off accumulated oil, dander, dust, and cosmetic residues. Your pool stays cleaner-looking and healthier for the whole family.
**Dual Centrifugal Pumps + Patented Dual Inlet — 85 GPM of Suction**: Twin centrifugal pumps deliver 85 GPM of powerful water flow, vacuuming leaves, insects, sand, pebbles, and hair from floor and walls with ease. The patented dual-inlet design keeps suction strong and wall-climbing stable even when the filter chamber is full—so performance never drops mid-cycle. Deep-sea motors withstand 200 m pressure and resist salt and chlorine for years of reliable service.
**Four Cleaning Modes, Including the Power-Boosting Ultra Clean**: Match every session to your pool's needs with four modes: Auto (1h/2h/3h), Floor-only, Walls-only, and the powerful Ultra Clean mode. Ultra Clean boosts pump power, water pressure, and flow rate to blast away stubborn, heavy debris—ideal after a storm or for pools with heavy buildup. One tap in the CHASING Bot App activates Ultra Clean, and the app also gives you scheduled cleaning and OTA upgrades.
**4.1L Extra-Large Filter Basket with 180µm Mesh — Optional 50µm Upgrade**: The 4.1L dual-zone filter basket captures everything from leaves, twigs, and gravel to fine sand and hair, while the 180µm nylon mesh traps tiny particles for crystal-clear water. The generous capacity means fewer trips to empty it, and an optional 50µm hyper-fine filter (pollen, dander, sebum) delivers ultra-fine filtration for swim-ready water all season long.
**2-Year Warranty — Buy with Total Peace of Mind**: We stand behind our investment with a 2-year warranty from the date of purchase, backed by dedicated customer support. Add IP68 waterproofing, corrosion-resistant deep-sea motors, and reinforced tracks that cross main drains without getting stuck—plus a lightweight 6.5 kg (14.3 lb) body that's effortless to lift and carry. Hydro 4 SE is built to perform season after season
