Buying guidance

Niya Sonar Ray or Niya Tracker 15: our take

Niya Sonar Ray and Niya Tracker 15 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

Niya Sonar Ray is intended for inground and above-ground pools, while Niya Tracker 15 is intended for above-ground pools. Niya Sonar Ray is rated for pools up to 26 ft; Niya Tracker 15 is rated up to 20 ft. Each cleans floor, so coverage alone does not separate them. Niya Sonar Ray's documented cleaning system includes Sonar navigation.

Filtration and debris

Both models include Basket.

Controls and day-to-day ownership

Both models provide one-touch starts and power-supply controls. Both use cordless battery power. Both are listed at 7.1 lb, so lifting effort is effectively the same.

Price, warranty and the decision

Both are listed at $199. Each lists a 1-year manufacturer warranty. Niya Sonar Ray and Niya Tracker 15 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.
