Buy Dolphin EscapeDolphin Premium 10 or Dolphin S50: our take
Dolphin Premium 10 and Dolphin S50 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
Dolphin Premium 10 is intended for inground and above-ground pools, while Dolphin S50 is intended for above-ground pools. Both are rated for pools up to 30 ft. Each cleans floor, so coverage alone does not separate them. Dolphin Premium 10 lists 1 active brush and CleverClean navigation. Dolphin S50 lists 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. Dolphin Premium 10 uses continuous corded power, while Dolphin S50 uses a 40 ft corded cable. Dolphin Premium 10 is listed at 14.6 lb versus 14 lb for Dolphin S50; that 0.5999999999999996 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Premium 10 is listed at $719 and Dolphin S50 at $649; Dolphin S50 is $70 less. Each lists a 2-year manufacturer warranty. Dolphin Premium 10 and Dolphin S50 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.
