Buy Dolphin QuantumDolphin Active 3000 or Dolphin Proteus DX3: our take
Dolphin Active 3000 and Dolphin Proteus DX3 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 and above-ground pools. Dolphin Active 3000 is rated for pools up to 50 ft; Dolphin Proteus DX3 is rated up to 33 ft.

Controls and day-to-day ownership
Dolphin Active 3000 provides a weekly timer and smartphone control; Dolphin Proteus DX3 provides a weekly timer and power-supply controls. Dolphin Active 3000 uses continuous corded power, while Dolphin Proteus DX3 uses a 50 ft corded cable. Dolphin Active 3000 is listed at 17.9 lb versus 14 lb for Dolphin Proteus DX3; that 3.8999999999999986 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Active 3000 is listed at $1,449 and Dolphin Proteus DX3 at $699; Dolphin Proteus DX3 is $750 less. Dolphin Active 3000 lists a 3-year warranty compared with 2 years for Dolphin Proteus DX3.
