Buying guidance

BWT RC50 or Polaris 9300 Sport Pool Cleaner F9300: our take

BWT RC50 and Polaris 9300 Sport Pool Cleaner F9300 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

Each cleans floor, so coverage alone does not separate them. BWT RC50's documented cleaning system includes 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

BWT RC50 provides no fully published timer, app or remote specification; Polaris 9300 Sport Pool Cleaner F9300 provides daily scheduling.

Price, warranty and the decision

BWT RC50 is listed at $1,399 and Polaris 9300 Sport Pool Cleaner F9300 at $1,393.60; Polaris 9300 Sport Pool Cleaner F9300 is $5.40 less. BWT RC50 and Polaris 9300 Sport Pool Cleaner F9300 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.
