Buy Dolphin EscapeDolphin E10 or Dolphin T15: our take
Dolphin E10 and Dolphin T15 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 above-ground pools. Dolphin E10 is rated for pools up to 33 ft; Dolphin T15 is rated up to 30 ft. Each cleans floor, so coverage alone does not separate them. Dolphin E10's documented cleaning system includes 1 active brush.
Filtration and debris
Both models include Basket.
Controls and day-to-day ownership
Both models provide one-touch starts and power-supply controls. Both use a 40 ft corded cable.
Price, warranty and the decision
Dolphin E10 is listed at $499 and Dolphin T15 at $649; Dolphin E10 is $150 less. Each lists a 2-year manufacturer warranty. Dolphin E10 and Dolphin T15 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Escape. Inground and above-ground pools up to 30 ft that need floor cleaning.
