Buy Dolphin QuantumDolphin Explorer E25 or Dolphin T25: our take
Dolphin Explorer E25 and Dolphin T25 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 T25 is intended for inground and above-ground pools. Dolphin Explorer E25 is rated for pools up to 50 ft; Dolphin T25 is rated up to 33 ft. Each cleans floor and walls, so coverage alone does not separate them. Dolphin T25's documented cleaning system includes 1 active brush.
Filtration and debris

Controls and day-to-day ownership
Dolphin Explorer E25 provides smartphone control; Dolphin T25 provides a weekly timer and power-supply controls.

Dolphin Explorer E25 and Dolphin T25 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Quantum.
