Buy Dolphin CaymanDolphin Explorer E25 or Dolphin Liberty 200: our take
Dolphin Explorer E25 and Dolphin Liberty 200 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 E25 is intended for inground pools, while Dolphin Liberty 200 is intended for inground and above-ground pools. Dolphin Explorer E25 has a published maximum pool length of 50 ft; the other model does not have a verified length in our source material. Each cleans floor and walls, so coverage alone does not separate them. Dolphin Liberty 200's documented cleaning system includes Dual DC motors.
Filtration and debris
Dolphin Liberty 200 has documented included filtration—Basket—while the other model's included media is not fully published. Dolphin Liberty 200 has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin Explorer E25 provides smartphone control; Dolphin Liberty 200 provides no fully published timer, app or remote specification.
Price, warranty and the decision
Dolphin Explorer E25 is listed at $899 and Dolphin Liberty 200 at $999; Dolphin Explorer E25 is $100 less. Each lists a 2-year manufacturer warranty. Dolphin Explorer E25 and Dolphin Liberty 200 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.
