Buy Dolphin EscapeDolphin Explorer E40 or Dolphin T15: our take
Dolphin Explorer E40 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
Dolphin Explorer E40 is intended for inground pools, while Dolphin T15 is intended for above-ground pools. Dolphin Explorer E40 is rated for pools up to 50 ft; Dolphin T15 is rated up to 30 ft. Each cleans floor, so coverage alone does not separate them. Dolphin T15's documented cleaning system includes 1 active brush.
Filtration and debris
Dolphin T15 has documented included filtration—Basket—while the other model's included media is not fully published. Dolphin T15 has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin Explorer E40 provides no fully published timer, app or remote specification; Dolphin T15 provides one-touch starts and power-supply controls.
Price, warranty and the decision
Dolphin Explorer E40 is listed at $1,599 and Dolphin T15 at $649; Dolphin T15 is $950 less. Dolphin Explorer E40 lists a 3-year warranty compared with 2 years for Dolphin T15. Dolphin Explorer E40 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.
