Buying guidance

Blue Helix One or Dolphin Active 10: our take

Blue Helix One and Dolphin Active 10 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

Blue Helix One is intended for inground pools, while Dolphin Active 10 is intended for above-ground pools. Dolphin Active 10 has a published maximum pool length of 30 ft; the other model does not have a verified length in our source material. Blue Helix One cleans floor, walls, and waterline; Dolphin Active 10 cleans floor. Dolphin Active 10's documented cleaning system includes 1 active brush.

Filtration and debris

Both models include Basket.

Controls and day-to-day ownership

Blue Helix One provides a weekly timer and smartphone control; Dolphin Active 10 provides one-touch starts and power-supply controls. Blue Helix One uses continuous corded power, while Dolphin Active 10 uses a 40 ft corded cable.

Price, warranty and the decision

Blue Helix One is listed at $579 and Dolphin Active 10 at $649; Blue Helix One is $70 less. Each lists a 2-year manufacturer warranty. Blue Helix One and Dolphin Active 10 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.
