Buying guidance

Niya Sonar 30 or Niya Tracker 55: our take

Niya Sonar 30 and Niya Tracker 55 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

Both robots are intended for inground and above-ground pools. Niya Sonar 30 is rated for pools up to 33 ft; Niya Tracker 55 is rated up to 40 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Niya Sonar 30 lists 2 active brushes, Sonar navigation, and Three brushless motors. Niya Tracker 55 lists 2 active brushes, Sonar navigation, and Dual drive motors.

Filtration and debris

Both models include Basket.

Controls and day-to-day ownership

Niya Sonar 30 provides one-touch starts and power-supply controls; Niya Tracker 55 provides one-touch starts and smartphone control. Both use cordless battery power. Niya Sonar 30 is listed at 19.2 lb versus 19.8 lb for Niya Tracker 55; that 0.6000000000000014 lb difference matters when lifting the robot from the pool.

Price, warranty and the decision

Niya Sonar 30 is listed at $379 and Niya Tracker 55 at $779; Niya Sonar 30 is $400 less. Niya Sonar 30 lists a 1-year warranty compared with 1.5 years for Niya Tracker 55. Niya Sonar 30 and Niya Tracker 55 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Quantum. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.
