Buy Dolphin QuantumDolphin Explorer E30 or Niya Tracker 35: our take
Dolphin Explorer E30 and Niya Tracker 35 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 E30 is rated for pools up to 50 ft; Niya Tracker 35 is rated up to 40 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them.

Dolphin Explorer E30 provides a weekly timer and smartphone control; Niya Tracker 35 provides one-touch starts. Dolphin Explorer E30 uses a 60 ft corded cable with an anti-tangle swivel, while Niya Tracker 35 uses cordless battery power.
