Buying guidance

Aquabot X2 or Aquabot X4: our take

Aquabot X2 and Aquabot X4 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 and above-ground pools. Aquabot X2 is rated for pools up to 40 ft; Aquabot X4 is rated up to 60 ft. Aquabot X2 cleans floor; Aquabot X4 cleans floor, walls, and waterline. Aquabot X2 lists 1 active brush. Aquabot X4 lists 1 active brush and Intelligent navigation.

Filtration and debris

Aquabot X4 has documented included filtration—Basket—while the other model's included media is not fully published. Aquabot X4 has the better documented path for bulky leaves and larger debris.

Controls and day-to-day ownership

Aquabot X2 provides no fully published timer, app or remote specification; Aquabot X4 provides a weekly timer.

Price, warranty and the decision

Aquabot X2 is listed at $497 and Aquabot X4 at $747; Aquabot X2 is $250 less. Each lists a 2-year manufacturer warranty. Aquabot X2 and Aquabot X4 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Quantum.
