Buy Dolphin CaymanDolphin Explorer E25 or Dolphin Premium 20: our take
Dolphin Explorer E25 and Dolphin Premium 20 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 rated for pools up to 50 ft; Dolphin Premium 20 is rated up to 33 ft. Each cleans floor and walls, so coverage alone does not separate them. Dolphin Premium 20's documented cleaning system includes 1 active brush and CleverClean navigation.

Dolphin Explorer E25 provides smartphone control; Dolphin Premium 20 provides one-touch starts and power-supply controls.
Price, warranty and the decision
Both are listed at $899. Each lists a 2-year manufacturer warranty. Dolphin Explorer E25 and Dolphin Premium 20 each have a specific fit, but neither is the Pool Express pick for this job.
