Buy Dolphin CaymanDolphin Active 10 or Dolphin EON 120d: our take
Dolphin Active 10 and Dolphin EON 120d 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 Active 10 is intended for above-ground pools, while Dolphin EON 120d is intended for inground and above-ground pools. Dolphin Active 10 is rated for pools up to 30 ft; Dolphin EON 120d is rated up to 50 ft. Dolphin Active 10 cleans floor; Dolphin EON 120d cleans floor, walls, and waterline. Dolphin Active 10 lists 1 active brush. Dolphin EON 120d lists SmartMap navigation.
Filtration and debris
Dolphin Active 10 includes Basket; Dolphin EON 120d includes Basket and UltraFilter. Dolphin EON 120d has the clearer documented edge for fine silt, pollen and sand.
Controls and day-to-day ownership
Dolphin Active 10 provides one-touch starts and power-supply controls; Dolphin EON 120d provides a weekly timer and smartphone control. Dolphin Active 10 uses a 40 ft corded cable, while Dolphin EON 120d uses cordless battery power. Dolphin Active 10 is listed at 14 lb versus 24.3 lb for Dolphin EON 120d; that 10.3 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Active 10 lists a 2-year warranty compared with 3 years for Dolphin EON 120d. Dolphin Active 10 and Dolphin EON 120d 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.
