Buy Dolphin QuantumAquabot Rapids 2000 or Dolphin Nautilus EON 120d: our take
Aquabot Rapids 2000 and Dolphin Nautilus EON 120d 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
Aquabot Rapids 2000 is intended for inground pools, while Dolphin Nautilus EON 120d is intended for inground and above-ground pools. Both are rated for pools up to 50 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Aquabot Rapids 2000 lists Gyroscope navigation. Dolphin Nautilus EON 120d lists 2 active brushes and SmartMap navigation.
Filtration and debris
Dolphin Nautilus EON 120d has documented included filtration—Basket and UltraFilter—while the other model's included media is not fully published. Dolphin Nautilus EON 120d has the clearer documented edge for fine silt, pollen and sand. Dolphin Nautilus EON 120d has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Aquabot Rapids 2000 provides included remote control; Dolphin Nautilus EON 120d provides a weekly timer and smartphone control.
Price, warranty and the decision
Aquabot Rapids 2000 is listed at $699 and Dolphin Nautilus EON 120d at $1,199; Aquabot Rapids 2000 is $500 less. Aquabot Rapids 2000 lists a 2-year warranty compared with 1 years for Dolphin Nautilus EON 120d. Aquabot Rapids 2000 and Dolphin Nautilus EON 120d 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.
