Buying guidance

Aquabot REVA or Aquabot X4: our take

Aquabot REVA 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

Aquabot REVA is intended for inground pools, while Aquabot X4 is intended for inground and above-ground 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 REVA lists Gyroscope navigation. 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 REVA provides smartphone control; Aquabot X4 provides a weekly timer.

Price, warranty and the decision

Aquabot REVA is listed at $499 and Aquabot X4 at $747; Aquabot REVA is $248 less. Each lists a 2-year manufacturer warranty. Aquabot REVA and Aquabot X4 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.
