Description
The CHASING Poolmate Hydro 4 Robotic Pool Cleaner is engineered for powerful, intelligent cleaning in medium to large pools. Designed to clean the pool floor, walls, and waterline, Hydro 4 uses a dual-pump system and advanced navigation to deliver consistent, thorough results.
Hydro 4 is available in three power configurations, allowing you to choose the setup that best fits your pool environment:
-
Hydro 4 Corded – Continuous AC power with a Wi-Fi power supply and 15m cable for uninterrupted cleaning.

Using the CHASING (POOLMATE) App, users can schedule cleanings, set delays, control the robot manually, activate one-click pickup, and manage cleaning modes via Wi-Fi cloud connectivity. Hydro 4 supports six cleaning modes: Regular, Fast, Ultra, Pool Bottom, Waterline, and Custom.
With a 5,070 GPH suction rate, dual centrifugal pumps, an active brush system, and a large 4.1L 180μm filter basket, Hydro 4 is built to handle heavy debris, leaves, and fine particles for a consistently clean pool.
