Buy Dolphin QuantumBlue Helix One or Dolphin Nautilus CC Supreme: our take
Blue Helix One and Dolphin Nautilus CC Supreme 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 pools. Dolphin Nautilus CC Supreme has a published maximum pool length of 50 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. Dolphin Nautilus CC Supreme's documented cleaning system includes 2 active brushes and CleverClean navigation.
Filtration and debris
Blue Helix One includes Basket; Dolphin Nautilus CC Supreme includes Standard filter and UltraFilter. Dolphin Nautilus CC Supreme has the clearer documented edge for fine silt, pollen and sand. Blue Helix One also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Blue Helix One provides a weekly timer and smartphone control; Dolphin Nautilus CC Supreme provides a weekly timer, smartphone control, and included remote control. Blue Helix One uses continuous corded power, while Dolphin Nautilus CC Supreme uses a 60 ft corded cable with an anti-tangle swivel.
Price, warranty and the decision
Blue Helix One is listed at $579 and Dolphin Nautilus CC Supreme at $1,599; Blue Helix One is $1,020 less. Blue Helix One lists a 2-year warranty compared with 3 years for Dolphin Nautilus CC Supreme. Blue Helix One and Dolphin Nautilus CC Supreme 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.
