Buying guidance

Dolphin Advantage or Dolphin Premium 20: our take

Dolphin Advantage and Dolphin Premium 20 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 Premium 20 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 lists 1 active brush. Dolphin Premium 20 lists 1 active brush and CleverClean navigation.

Filtration and debris

Both models include Basket.

Controls and day-to-day ownership

Dolphin Advantage provides a weekly timer and power-supply controls; Dolphin Premium 20 provides one-touch starts and power-supply controls. Dolphin Advantage uses a 50 ft corded cable, while Dolphin Premium 20 uses continuous corded power. Dolphin Advantage is listed at 14 lb versus 14.6 lb for Dolphin Premium 20; that 0.5999999999999996 lb difference matters when lifting the robot from the pool.

Price, warranty and the decision

Dolphin Advantage is listed at $699 and Dolphin Premium 20 at $899; Dolphin Advantage is $200 less. Each lists a 2-year manufacturer warranty. Dolphin Advantage and Dolphin Premium 20 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.
