Buying guidance

Aquabot X2 or BWT RC50: our take

Aquabot X2 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 X2 is intended for inground and above-ground pools, while BWT RC50 is intended for inground pools. Aquabot X2 has a published maximum pool length of 40 ft; the other model does not have a verified length in our source material. Each cleans floor, so coverage alone does not separate them. Aquabot X2 lists 1 active brush. BWT RC50 lists 2 active brushes.

Filtration and debris

The available manufacturer records do not fully identify the filter media supplied with either robot, so filtration should be confirmed before ordering.

Controls and day-to-day ownership

Both models provide no fully published timer, app or remote specification.

Price, warranty and the decision

Aquabot X2 is listed at $497 and BWT RC50 at $1,399; Aquabot X2 is $902 less. Aquabot X2 lists a 2-year warranty compared with 3 years for BWT RC50. Aquabot X2 and BWT RC50 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Escape. Inground and above-ground pools up to 30 ft that need floor cleaning.
