Buy Clear SBWT RC50 or Dolphin Explorer E25: our take
BWT RC50 and Dolphin Explorer E25 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 Explorer E25 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 Explorer E25 cleans floor and walls. 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; Dolphin Explorer E25 provides smartphone control.
Price, warranty and the decision
BWT RC50 is listed at $1,399 and Dolphin Explorer E25 at $899; Dolphin Explorer E25 is $500 less. BWT RC50 lists a 3-year warranty compared with 2 years for Dolphin Explorer E25. BWT RC50 and Dolphin Explorer E25 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Clear S. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.
