Buy Dolphin QuantumBlue Helix One or Niya Sonar 30: our take
Blue Helix One and Niya Sonar 30 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 Sonar 30 is intended for inground and above-ground pools. Niya Sonar 30 has a published maximum pool length of 33 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 Sonar 30's documented cleaning system includes 2 active brushes, Sonar navigation, and Three brushless 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 Sonar 30 provides one-touch starts and power-supply controls. Blue Helix One uses continuous corded power, while Niya Sonar 30 uses cordless battery power.
Price, warranty and the decision
Blue Helix One is listed at $579 and Niya Sonar 30 at $379; Niya Sonar 30 is $200 less. Blue Helix One lists a 2-year warranty compared with 1 years for Niya Sonar 30. Blue Helix One and Niya Sonar 30 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.
