The Maytronics Dolphin S200 Robotic pool cleaning vacuum is powerfully nimble on both the pool floor and vertical wall surfaces. Not only used for floor cleaning, but this model has intense wall and waterline scrubbing. With superior self contained filtering capabilities, dirt and debris can’t hide from this underwater cleaning machine. You no longer have vacuum hoses all over the pool and no more clogging your pipes as with suction based pool vacuums.
