Buy Dolphin CaymanDolphin Advantage or Dolphin Liberty 200: our take
Dolphin Advantage and Dolphin Liberty 200 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 Liberty 200 is intended for inground and above-ground pools. Dolphin Advantage has a published maximum pool length of 33 ft; the other model does not have a verified length in our source material. Each cleans floor and walls, so coverage alone does not separate them. Dolphin Advantage lists 1 active brush. Dolphin Liberty 200 lists Dual DC motors.
Filtration and debris
Both models include Basket.
Controls and day-to-day ownership
Dolphin Advantage provides a weekly timer and power-supply controls; Dolphin Liberty 200 provides no fully published timer, app or remote specification. Dolphin Advantage uses a 50 ft corded cable, while Dolphin Liberty 200 uses cordless battery power.
Price, warranty and the decision
Dolphin Advantage is listed at $699 and Dolphin Liberty 200 at $999; Dolphin Advantage is $300 less. Each lists a 2-year manufacturer warranty. Dolphin Advantage and Dolphin Liberty 200 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.
