Dolphin Wave 120 or Dolphin Wave 140: our take

Dolphin Wave 120 and Dolphin Wave 140 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.

Both robots are intended for commercial pools. Dolphin Wave 120 is rated for pools up to 121 ft; Dolphin Wave 140 is rated up to 127 ft.

Filtration and debris

Controls and day-to-day ownership

Dolphin Wave 120 provides no fully published timer, app or remote specification; Dolphin Wave 140 provides one-touch starts and included remote control. Dolphin Wave 120 uses continuous corded power, while Dolphin Wave 140 uses a 140 ft corded cable.

Price, warranty and the decision

Dolphin Wave 120 is listed at $7,899 and Dolphin Wave 140 at $8,499; Dolphin Wave 120 is $600 less. Dolphin Wave 120 lists a 2-year warranty compared with 3 years for Dolphin Wave 140.
