Dolphin M550
Floor, wall and waterline cleaning for in-ground pools up to 50 ft
The Dolphin M550 is a corded robotic cleaner made by Maytronics for in-ground pools up to 50 ft long. It cleans the floor, climbs walls and scrubs the waterline during its default 2-hour cycle. Two brushes, including an active brush, handle scrubbing. An anti-tangling swivel helps limit cable twisting as it moves. Debris collects in the top-access Combine Filter Kit, and an Ultra-Fine Filter Kit is also included.
