Buying guidance

Dolphin Active 15 or Dolphin Advantage: our take

Dolphin Active 15 and Dolphin Advantage 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 15 is intended for inground and above-ground pools, while Dolphin Advantage is intended for inground 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's documented cleaning system includes 1 active brush.

Filtration and debris

Dolphin Active 15 includes Basket and UltraFilter; Dolphin Advantage includes Basket. That gives Dolphin Active 15 the clearer documented edge for fine silt, pollen and sand.

Controls and day-to-day ownership

Both models provide a weekly timer and power-supply controls. Dolphin Active 15 uses a 40 ft corded cable, while Dolphin Advantage uses a 50 ft corded cable. Both are listed at 14 lb, so lifting effort is effectively the same.

Price, warranty and the decision

Dolphin Active 15 is listed at $849 and Dolphin Advantage at $699; Dolphin Advantage is $150 less. Each lists a 2-year manufacturer warranty. Dolphin Active 15 and Dolphin Advantage 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.

Dolphin Active 15 vs Dolphin Advantage 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.
