Why Dolphin Liberty 400?

Floor, Wall and Waterline Cleaning

Dolphin Liberty 400 cleans the floor, walls and waterline in pools up to 33 ft, reducing the areas left for manual brushing.

Easy Top-Load Filtration

The top-load Combine Filter Kit traps debris as the robot moves through the pool, and the included Ultra-Fine Filter Kit adds a second filtration option.

Cordless Convenience

Rechargeable power keeps a floating cable out of the water and a power supply off the pool deck.
