Buy Dolphin CaymanDolphin Advantage or Dolphin Proteus DX3: our take
Dolphin Advantage and Dolphin Proteus DX3 are compared on pool fit, cleaning reach, debris handling, controls and ownership details. The recommendation is based on the job the robot must do—not a simple feature count.
Pool fit and cleaning reach
Dolphin Advantage is intended for inground pools, while Dolphin Proteus DX3 is intended for inground and above-ground pools. Both are rated for pools up to 33 ft. Each cleans floor and walls, so coverage alone does not separate them. Dolphin Advantage's documented cleaning system includes 1 active brush.
Filtration and debris
Both models include Basket.
Controls and day-to-day ownership
Both models provide a weekly timer and power-supply controls. Both use a 50 ft corded cable. Both are listed at 14 lb, so lifting effort is effectively the same.
Price, warranty and the decision
Both are listed at $699. Each lists a 2-year manufacturer warranty. Dolphin Advantage and Dolphin Proteus DX3 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Cayman. Inground and above-ground pools up to 40 ft that need floor and wall cleaning.
