Buy Dolphin QuantumDolphin Proteus DX5i or Dolphin Triton PS: our take
Dolphin Proteus DX5i and Dolphin Triton PS 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. Both are rated for pools up to 50 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin Proteus DX5i's documented cleaning system includes 1 active brush.
Filtration and debris
Both models include Basket.
Controls and day-to-day ownership
Dolphin Proteus DX5i provides smartphone control; Dolphin Triton PS 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 Proteus DX5i is listed at $1,299 and Dolphin Triton PS at $1,099; Dolphin Triton PS is $200 less. Each lists a 2-year manufacturer warranty. Dolphin Proteus DX5i and Dolphin Triton PS 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.
