Buy Dolphin Wave 100Dolphin W20 or Dolphin Wave 120: our take
Dolphin W20 and Dolphin Wave 120 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 commercial pools. Dolphin Wave 120 has a published maximum pool length of 121 ft; the other model does not have a verified length in our source material. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin W20's documented cleaning system includes Commercial-grade motors.
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. Both use continuous corded power.
Price, warranty and the decision
Dolphin W20 is listed at $1,999 and Dolphin Wave 120 at $7,899; Dolphin W20 is $5,900 less. Dolphin W20 lists a 3-year warranty compared with 2 years for Dolphin Wave 120. Dolphin W20 and Dolphin Wave 120 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Wave 100. Commercial pools up to 88 ft that need floor, wall and waterline cleaning.
