Buying guidance

Aquabot X4 or Blue Helix One: our take

Aquabot X4 and Blue Helix One 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

Aquabot X4 is intended for inground and above-ground pools, while Blue Helix One is intended for inground pools. Aquabot X4 has a published maximum pool length of 60 ft; the other model does not have a verified length in our source material. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Aquabot X4's documented cleaning system includes 1 active brush and Intelligent navigation.

Filtration and debris

Both models include Basket.

Controls and day-to-day ownership

Aquabot X4 provides a weekly timer; Blue Helix One provides a weekly timer and smartphone control. Aquabot X4 uses a 60 ft corded cable with an anti-tangle swivel, while Blue Helix One uses continuous corded power.

Price, warranty and the decision

Aquabot X4 is listed at $747 and Blue Helix One at $579; Blue Helix One is $168 less. Each lists a 2-year manufacturer warranty. Aquabot X4 and Blue Helix One each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Quantum. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.
