Buy Dolphin QuantumDolphin Explorer E25 or Dolphin T35: our take
Dolphin Explorer E25 and Dolphin T35 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.

Dolphin Explorer E25 provides smartphone control; Dolphin T35 provides a weekly timer and smartphone control.
Price, warranty and the decision
