The Dolphin S50 above ground robotic pool cleaner is the newest member of the Dolphin robotic cleaner team, the S50 is the first fully robotic cleaner for ABOVE GROUND pools! No more reaching over pool walls or bending down from the deck to get that squeaky clean pool. Let the S50 do the work for you! This small but mighty cleaner’s active brush turns two times as quickly as other robotic cleaners. Unlike other aboveground cleaners, the S50 uses robotic scanning technology to ensure that every inch of your pool’s floor is cleaned efficiently. What’s more, the S50 uses a self-contained, top-access filter canister that saves you and your pool filter the stress of traditional vacuuming or suction cleaners.
