Buying guidance

Dolphin Premium 40 or Dolphin Triton PS: our take

Dolphin Premium 40 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 Premium 40 lists 2 active brushes and CleverClean navigation. Dolphin Triton PS lists 1 active brush.

Filtration and debris

Dolphin Premium 40 includes Basket and UltraFilter; Dolphin Triton PS includes Basket. That gives Dolphin Premium 40 the clearer documented edge for fine silt, pollen and sand.

Controls and day-to-day ownership

Dolphin Premium 40 provides a weekly timer and smartphone control; Dolphin Triton PS provides a weekly timer and power-supply controls. Dolphin Premium 40 uses continuous corded power, while Dolphin Triton PS uses a 60 ft corded cable with an anti-tangle swivel.

Price, warranty and the decision

Dolphin Premium 40 is listed at $1,629 and Dolphin Triton PS at $1,099; Dolphin Triton PS is $530 less. Each lists a 2-year manufacturer warranty. Dolphin Premium 40 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.

Dolphin Premium 40 vs Dolphin Triton PS specifications
