Buy Dolphin CaymanDolphin Liberty 300 or Dolphin Premium 10: our take
Dolphin Liberty 300 and Dolphin Premium 10 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. Dolphin Premium 10 has a published maximum pool length of 30 ft; the other model does not have a verified length in our source material. Dolphin Liberty 300 cleans floor and walls; Dolphin Premium 10 cleans floor. Dolphin Liberty 300 lists Dual DC motors. Dolphin Premium 10 lists 1 active brush and CleverClean navigation.
Filtration and debris
Dolphin Liberty 300 includes Basket and UltraFilter; Dolphin Premium 10 includes Basket. That gives Dolphin Liberty 300 the clearer documented edge for fine silt, pollen and sand.
Controls and day-to-day ownership
Dolphin Liberty 300 provides no fully published timer, app or remote specification; Dolphin Premium 10 provides one-touch starts and power-supply controls. Dolphin Liberty 300 uses cordless battery power, while Dolphin Premium 10 uses continuous corded power.
Price, warranty and the decision
Dolphin Liberty 300 is listed at $1,099 and Dolphin Premium 10 at $719; Dolphin Premium 10 is $380 less. Each lists a 2-year manufacturer warranty. Dolphin Liberty 300 and Dolphin Premium 10 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.
