Buying guidance

Blue Helix One or Niya Tracker 35: our take

Blue Helix One and Niya Tracker 35 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

Blue Helix One is intended for inground pools, while Niya Tracker 35 is intended for inground and above-ground pools. Niya Tracker 35 has a published maximum pool length of 40 ft; the other model does not have a verified length in our source material. 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

Blue Helix One provides a weekly timer and smartphone control; Niya Tracker 35 provides one-touch starts. Blue Helix One uses continuous corded power, while Niya Tracker 35 uses cordless battery power.

Price, warranty and the decision

Blue Helix One is listed at $579 and Niya Tracker 35 at $539; Niya Tracker 35 is $40 less. Blue Helix One lists a 2-year warranty compared with 1.5 years for Niya Tracker 35. Blue Helix One and Niya Tracker 35 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.
