Buying guidance

Dolphin Advantage Ultra or Dolphin Explorer E40: our take

Dolphin Advantage Ultra and Dolphin Explorer E40 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 pools. Both are rated for pools up to 50 ft. Dolphin Advantage Ultra cleans floor, walls, and waterline; Dolphin Explorer E40 cleans floor.

Filtration and debris

Dolphin Advantage Ultra has documented included filtration—Basket—while the other model's included media is not fully published. Dolphin Advantage Ultra also has the better documented path for bulky leaves and larger debris.

Controls and day-to-day ownership

Dolphin Advantage Ultra provides a weekly timer and power-supply controls; Dolphin Explorer E40 provides no fully published timer, app or remote specification.

Price, warranty and the decision

Dolphin Advantage Ultra is listed at $1,099 and Dolphin Explorer E40 at $1,599; Dolphin Advantage Ultra is $500 less. Dolphin Advantage Ultra lists a 2-year warranty compared with 3 years for Dolphin Explorer E40. Dolphin Advantage Ultra and Dolphin Explorer E40 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Quantum.
