Blue Helix One or BWT RC50: our take

Blue Helix One 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

Both robots are intended for inground pools. Blue Helix One cleans floor, walls, and waterline; BWT RC50 cleans floor. BWT RC50's documented cleaning system includes 2 active brushes.

Filtration and debris

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

Controls and day-to-day ownership

Blue Helix One provides a weekly timer and smartphone control; BWT RC50 provides no fully published timer, app or remote specification.

Price, warranty and the decision

Blue Helix One is listed at $579 and BWT RC50 at $1,399; Blue Helix One is $820 less. Blue Helix One lists a 2-year warranty compared with 3 years for BWT RC50. Blue Helix One 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.
