AIRROBO CP400 4-in-1 Omni

The CP400 4-in-1 Omni is the top model of AIRROBO, the consumer brand of the Chinese robot maker UBTech, which lists it in the pool-cleaner section of its own site. It is a fully submersible machine that is dropped into a swimming pool and left to work on its own: it cleans the floor, climbs the walls, scrubs the waterline where suncream and dust collect, and — with a separate surface module — skims floating leaves off the top. Four motors do the work: two drive the tracks, two run the pumps, which is what lets the robot hold itself against a vertical wall while still sucking. The manufacturer calls its navigation NaviClean: the robot maps the pool and covers it in a zigzag rather than the random bouncing of cheap pool cleaners, and a dedicated waterline mode sends it around the rim. Cleaning can be started, scheduled and switched from a phone app or a Bluetooth remote, and when the cycle ends or the battery runs low the machine drives itself to the edge of the pool so that it can be lifted out without wading in. The published figures describe a large machine rather than a toy: 356 x 635 x 533 mm, 20.4 kg, a 10 400 mAh battery giving 150 minutes of work and recharging in two hours, a four-litre top-loading filter basket and an IP68 rating for full submersion. AIRROBO rates it for above-ground and in-ground pools of up to 3 229 square feet, about 300 square metres. The US price is 1 099.99 dollars. Two caveats belong on the record. The manufacturer publishes no launch date for the model; the 2026 year in this profile is taken from the date the product appeared in AIRROBO's own online store (6 February 2026) and is our assumption, not the company's statement. And the same brand sells a cheaper CP400 2-in-1 and a CP400Lite — different machines with the same number in the name.
