Buying guidance

Dolphin Active 10 or Dolphin T15: our take

Dolphin Active 10 and Dolphin T15 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 above-ground pools. Both are rated for pools up to 30 ft. Each cleans floor, so coverage alone does not separate them. Dolphin Active 10's documented cleaning system includes 1 active brush.

Filtration and debris

Both models include Basket.

Controls and day-to-day ownership

Both models provide one-touch starts and power-supply controls. Both use a 40 ft corded cable. Both are listed at 14 lb, so lifting effort is effectively the same.

Price, warranty and the decision

Both are listed at $649. Each lists a 2-year manufacturer warranty. Dolphin Active 10 and Dolphin T15 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Escape. Inground and above-ground pools up to 30 ft that need floor cleaning.

Dolphin Active 10 vs Dolphin T15 specifications

Use pool fit first. Price and app control do not make up for a robot that cannot cover the length or surfaces you need cleaned.
