Buy Dolphin CaymanClear UV or Niya Sonar 20: our take
Clear UV and Niya Sonar 20 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
Clear UV is intended for inground pools, while Niya Sonar 20 is intended for above-ground pools. Clear UV is rated for pools up to 50 ft; Niya Sonar 20 is rated up to 26 ft. Clear UV cleans floor, walls, and waterline; Niya Sonar 20 cleans floor. Clear UV lists 2 active brushes, Intelligent navigation (C9 microprocessor), and Quad (2 pump + 2 drive) motors. Niya Sonar 20 lists Sonar navigation and Dual drive motors.
Filtration and debris
Clear UV includes UltraFilter; Niya Sonar 20 includes Basket. That gives Clear UV the clearer documented edge for fine silt, pollen and sand. Niya Sonar 20 has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Clear UV provides a weekly timer, smartphone control, and included remote control; Niya Sonar 20 provides one-touch starts and power-supply controls. Clear UV uses a 59 ft corded cable with an anti-tangle swivel, while Niya Sonar 20 uses cordless battery power. Clear UV is listed at 27.6 lb versus 10 lb for Niya Sonar 20; that 17.6 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Clear UV is listed at $1,999 and Niya Sonar 20 at $199; Niya Sonar 20 is $1,800 less. Clear UV lists a 3-year warranty compared with 1 years for Niya Sonar 20. Clear UV and Niya Sonar 20 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Cayman. Inground and above-ground pools up to 40 ft that need floor and wall cleaning.
