Buying guidance

Dolphin S50 or Dolphin T60: our take

Dolphin S50 and Dolphin T60 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 S50 is intended for above-ground pools, while Dolphin T60 is intended for inground pools. Dolphin S50 is rated for pools up to 30 ft; Dolphin T60 is rated up to 50 ft. Dolphin S50 cleans floor; Dolphin T60 cleans floor, walls, and waterline. Dolphin S50 lists 1 active brush. Dolphin T60 lists 2 active brushes and CleverClean navigation.

Filtration and debris

Dolphin S50 includes Basket; Dolphin T60 includes Basket and UltraFilter. Dolphin T60 has the clearer documented edge for fine silt, pollen and sand.

Controls and day-to-day ownership

Dolphin S50 provides one-touch starts and power-supply controls; Dolphin T60 provides a weekly timer and smartphone control. Dolphin S50 uses a 40 ft corded cable, while Dolphin T60 uses continuous corded power. Dolphin S50 is listed at 14 lb versus 24.3 lb for Dolphin T60; that 10.3 lb difference matters when lifting the robot from the pool.

Price, warranty and the decision

Dolphin S50 is listed at $649 and Dolphin T60 at $2,249; Dolphin S50 is $1,600 less. Dolphin S50 lists a 2-year warranty compared with 3 years for Dolphin T60. Dolphin S50 and Dolphin T60 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Cayman. Inground and above-ground pools up to 40 ft that need floor and wall cleaning.
