Product Features
Powerful Suction and Cleaning Capability
The HISION SAT25 is equipped with dual-drive motors and dual high-adhesion PVC brushes, delivering 4068 GPH (Gallons Per Hour) of powerful suction. This allows it to effectively scrub and lift dirt, leaves, sand, and stubborn grime from various pool surfaces, including tile, mosaic, glass, concrete, and vinyl floors.

Advanced Smart Navigation 3.0
Featuring Navigation 3.0 technology, the robot intelligently maps and optimizes its cleaning routes for full pool coverage. It minimizes overlaps and avoids missed areas, ensuring a faster and more thorough clean. This includes navigating slopes, drains, steps, and ledges as shallow as 1.6ft.

Floor, Wall, Waterline, and Stairs Cleaning
Built with rugged caterpillar treads, the 4-in-1 automatic pool cleaner provides exceptional traction and stability. It navigates all pool surfaces, including drains, steps, corners, and slopes, ensuring thorough cleaning of the floor, walls, and waterline with ease. The strong suction also helps prevent tilting, keeping the cleaner firmly against the wall during vertical cleaning.

Cordless Design and Extended Runtime
The cordless design eliminates tangled wires, allowing the cleaner to move freely and efficiently. It offers up to 180 minutes of continuous cleaning on a single charge, covering in-ground pools up to 2100 sq.ft. When battery levels drop to 15%, the cleaner automatically parks near the pool edge for easy retrieval.
