Buy Dolphin QuantumDolphin Advantage Pro or Dolphin Proteus DX4: our take
Dolphin Advantage Pro and Dolphin Proteus DX4 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 Advantage Pro has a published maximum pool length of 50 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 Proteus DX4's documented cleaning system includes 1 active brush.
Filtration and debris
Both models include Basket.
Controls and day-to-day ownership
Dolphin Advantage Pro provides a weekly timer and smartphone control; Dolphin Proteus DX4 provides a weekly timer and power-supply controls. Both use a 60 ft corded cable with an anti-tangle swivel.
Price, warranty and the decision
Dolphin Advantage Pro is listed at $1,399 and Dolphin Proteus DX4 at $1,199; Dolphin Proteus DX4 is $200 less. Each lists a 2-year manufacturer warranty. Dolphin Advantage Pro and Dolphin Proteus DX4 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Quantum. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.
