Buy Dolphin CaymanDolphin Active 15 or Dolphin Premium 20: our take
Dolphin Active 15 and Dolphin Premium 20 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. Both are rated for pools up to 33 ft. Each cleans floor and walls, so coverage alone does not separate them. Dolphin Active 15 lists 1 active brush. Dolphin Premium 20 lists 1 active brush and CleverClean navigation.
Filtration and debris
Dolphin Active 15 includes Basket and UltraFilter; Dolphin Premium 20 includes Basket. That gives Dolphin Active 15 the clearer documented edge for fine silt, pollen and sand.
Controls and day-to-day ownership
Dolphin Active 15 provides a weekly timer and power-supply controls; Dolphin Premium 20 provides one-touch starts and power-supply controls. Dolphin Active 15 uses a 40 ft corded cable, while Dolphin Premium 20 uses continuous corded power. Dolphin Active 15 is listed at 14 lb versus 14.6 lb for Dolphin Premium 20; that 0.5999999999999996 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Active 15 is listed at $849 and Dolphin Premium 20 at $899; Dolphin Active 15 is $50 less. Each lists a 2-year manufacturer warranty. Dolphin Active 15 and Dolphin Premium 20 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.
