Buy Dolphin QuantumDolphin Explorer E25 or Dolphin Explorer E40: our take
Dolphin Explorer E25 and Dolphin Explorer E40 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
Both robots are intended for inground pools. Both are rated for pools up to 50 ft. Dolphin Explorer E25 cleans floor and walls; Dolphin Explorer E40 cleans floor.
Filtration and debris
The available manufacturer records do not fully identify the filter media supplied with either robot, so filtration should be confirmed before ordering.
Controls and day-to-day ownership
Dolphin Explorer E25 provides smartphone control; Dolphin Explorer E40 provides no fully published timer, app or remote specification.
Price, warranty and the decision
Dolphin Explorer E25 is listed at $899 and Dolphin Explorer E40 at $1,599; Dolphin Explorer E25 is $700 less. Dolphin Explorer E25 lists a 2-year warranty compared with 3 years for Dolphin Explorer E40. Dolphin Explorer E25 and Dolphin Explorer E40 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Quantum. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.
