Buying guidance

Niya Tracker 35 or Niya Tracker 55: our take

Niya Tracker 35 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. Both are rated for pools up to 40 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Niya Tracker 35's documented cleaning system includes 2 active brushes, Sonar navigation, and Dual drive motors.

Filtration and debris

Both models include Basket.

Controls and day-to-day ownership

Niya Tracker 35 provides one-touch starts; Niya Tracker 55 provides one-touch starts and smartphone control. Both use cordless battery power. Niya Tracker 35 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 Tracker 35 is listed at $539 and Niya Tracker 55 at $779; Niya Tracker 35 is $240 less. Each lists a 1.5-year manufacturer warranty. Niya Tracker 35 and Niya Tracker 55 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Clear UV. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.
