Aquabot X4 or BWT RC50: our take

Aquabot X4 and BWT RC50 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 BWT RC50 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. Aquabot X4 cleans floor, walls, and waterline; BWT RC50 cleans floor. Aquabot X4 lists 1 active brush and Intelligent navigation. BWT RC50 lists 2 active brushes.

Filtration and debris

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

Controls and day-to-day ownership

Aquabot X4 provides a weekly timer; BWT RC50 provides no fully published timer, app or remote specification.

Price, warranty and the decision

Aquabot X4 is listed at $747 and BWT RC50 at $1,399; Aquabot X4 is $652 less. Aquabot X4 lists a 2-year warranty compared with 3 years for BWT RC50. Aquabot X4 and BWT RC50 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Clear UV. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.
