Buying guidance

Dolphin Advantage or Dolphin T25: our take

Dolphin Advantage and Dolphin T25 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 Advantage is intended for inground pools, while Dolphin T25 is 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 Advantage's documented cleaning system includes 1 active brush.

Filtration and debris

Dolphin Advantage includes Basket; Dolphin T25 includes Basket and UltraFilter. Dolphin T25 has 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. Both use a 50 ft corded cable. Dolphin Advantage is listed at 14 lb versus 15 lb for Dolphin T25; that 1 lb difference matters when lifting the robot from the pool.

Price, warranty and the decision

Dolphin Advantage is listed at $699 and Dolphin T25 at $849; Dolphin Advantage is $150 less. Each lists a 2-year manufacturer warranty. Dolphin Advantage and Dolphin T25 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 Advantage vs Dolphin T25 specifications
