Buying guidance

BWT RC50 or Dolphin Advantage Ultra: our take

BWT RC50 and Dolphin Advantage Ultra 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 pools. Dolphin Advantage Ultra has a published maximum pool length of 50 ft; the other model does not have a verified length in our source material. BWT RC50 cleans floor; Dolphin Advantage Ultra cleans floor, walls, and waterline. BWT RC50's documented cleaning system includes 2 active brushes.

Filtration and debris

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

Controls and day-to-day ownership

BWT RC50 provides no fully published timer, app or remote specification; Dolphin Advantage Ultra provides a weekly timer and power-supply controls.

Price, warranty and the decision

BWT RC50 is listed at $1,399 and Dolphin Advantage Ultra at $1,099; Dolphin Advantage Ultra is $300 less. BWT RC50 lists a 3-year warranty compared with 2 years for Dolphin Advantage Ultra. BWT RC50 and Dolphin Advantage Ultra 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.
