Buy Dolphin EscapeDolphin Explorer E40 or Niya Sonar 10: our take
Dolphin Explorer E40 and Niya Sonar 10 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 E40 is intended for inground pools, while Niya Sonar 10 is intended for inground and above-ground pools. Dolphin Explorer E40 is rated for pools up to 50 ft; Niya Sonar 10 is rated up to 20 ft. Each cleans floor, so coverage alone does not separate them. Niya Sonar 10's documented cleaning system includes Dual drive motors.
Filtration and debris
Niya Sonar 10 has documented included filtration—Basket—while the other model's included media is not fully published. Niya Sonar 10 has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin Explorer E40 provides no fully published timer, app or remote specification; Niya Sonar 10 provides one-touch starts and power-supply controls.
Price, warranty and the decision
Dolphin Explorer E40 is listed at $1,599 and Niya Sonar 10 at $149; Niya Sonar 10 is $1,450 less. Dolphin Explorer E40 lists a 3-year warranty compared with 1 years for Niya Sonar 10. Dolphin Explorer E40 and Niya Sonar 10 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Escape. Inground and above-ground pools up to 30 ft that need floor cleaning.
