Buy Dolphin PremierDolphin Premium 60 or Dolphin Proteus DX4: our take
Dolphin Premium 60 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 Premium 60 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 Premium 60 lists 2 active brushes and CleverClean navigation. Dolphin Proteus DX4 lists 1 active brush.
Filtration and debris
Dolphin Premium 60 includes Basket and UltraFilter; Dolphin Proteus DX4 includes Basket. That gives Dolphin Premium 60 the clearer documented edge for fine silt, pollen and sand.
Controls and day-to-day ownership
Dolphin Premium 60 provides a weekly timer and smartphone control; Dolphin Proteus DX4 provides a weekly timer and power-supply controls. Dolphin Premium 60 uses continuous corded power, while Dolphin Proteus DX4 uses a 60 ft corded cable with an anti-tangle swivel.
Price, warranty and the decision
Dolphin Premium 60 is listed at $2,249 and Dolphin Proteus DX4 at $1,199; Dolphin Proteus DX4 is $1,050 less. Dolphin Premium 60 lists a 3-year warranty compared with 2 years for Dolphin Proteus DX4. Dolphin Premium 60 and Dolphin Proteus DX4 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Premier. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris and heavy leaves.
