Buy Dolphin QuantumDolphin Active 20 or Dolphin Triton PS Plus: our take
Dolphin Active 20 and Dolphin Triton PS Plus 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 Active 20 lists 1 active brush. Dolphin Triton PS Plus lists 2 active brushes and CleverClean navigation.
Filtration and debris
Dolphin Active 20 includes Basket and UltraFilter; Dolphin Triton PS Plus includes Basket. That gives Dolphin Active 20 the clearer documented edge for fine silt, pollen and sand.
Controls and day-to-day ownership
Dolphin Active 20 provides a weekly timer and power-supply controls; Dolphin Triton PS Plus provides a weekly timer and smartphone control. Both use a 60 ft corded cable with an anti-tangle swivel.
Price, warranty and the decision
Dolphin Active 20 is listed at $1,119 and Dolphin Triton PS Plus at $1,199; Dolphin Active 20 is $80 less. Each lists a 2-year manufacturer warranty. Dolphin Active 20 and Dolphin Triton PS Plus 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.
