Buying guidance

Dolphin Active 15 or Dolphin Active Solo: our take

Dolphin Active 15 and Dolphin Active Solo 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 Active Solo lists 1 active brush and CleverClean navigation.

Filtration and debris

Dolphin Active 15 includes Basket and UltraFilter; Dolphin Active Solo 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 Active Solo provides one-touch starts and power-supply controls. Dolphin Active 15 uses a 40 ft corded cable, while Dolphin Active Solo uses continuous corded power. Dolphin Active 15 is listed at 14 lb versus 14.6 lb for Dolphin Active Solo; 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 Active Solo at $599; Dolphin Active Solo is $250 less. Each lists a 2-year manufacturer warranty. Dolphin Active 15 and Dolphin Active Solo 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.
