Buy Dolphin CaymanDolphin Liberty 200 or Dolphin Liberty 300: our take
Dolphin Liberty 200 and Dolphin Liberty 300 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
Both robots are intended for inground and above-ground pools. Each cleans floor and walls, so coverage alone does not separate them. Dolphin Liberty 200's documented cleaning system includes Dual DC motors.
Filtration and debris
Dolphin Liberty 200 includes Basket; Dolphin Liberty 300 includes Basket and UltraFilter. Dolphin Liberty 300 has the clearer documented edge for fine silt, pollen and sand.
Controls and day-to-day ownership
Both models provide no fully published timer, app or remote specification. Both use cordless battery power.
Price, warranty and the decision
Dolphin Liberty 200 is listed at $999 and Dolphin Liberty 300 at $1,099; Dolphin Liberty 200 is $100 less. Each lists a 2-year manufacturer warranty. Dolphin Liberty 200 and Dolphin Liberty 300 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.
