Buy Dolphin QuantumDolphin Nautilus CC Plus or Dolphin Nautilus EON 120d: our take
Dolphin Nautilus CC Plus 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
Both robots are intended for inground and above-ground pools. Both are rated for pools up to 50 ft. Dolphin Nautilus CC Plus cleans floor and walls; Dolphin Nautilus EON 120d cleans floor, walls, and waterline. Dolphin Nautilus CC Plus lists 2 active brushes and CleverClean navigation. Dolphin Nautilus EON 120d lists 2 active brushes and SmartMap navigation.
Filtration and debris
Dolphin Nautilus CC Plus includes Standard filter; Dolphin Nautilus EON 120d includes Basket and UltraFilter. 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
Both models provide a weekly timer and smartphone control. Dolphin Nautilus CC Plus uses a 60 ft corded cable with an anti-tangle swivel, while Dolphin Nautilus EON 120d uses cordless battery power. Dolphin Nautilus CC Plus is listed at 20 lb versus 24.3 lb for Dolphin Nautilus EON 120d; that 4.300000000000001 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Nautilus CC Plus is listed at $949 and Dolphin Nautilus EON 120d at $1,199; Dolphin Nautilus CC Plus is $250 less. Dolphin Nautilus CC Plus lists a 2.5-year warranty compared with 1 years for Dolphin Nautilus EON 120d. Dolphin Nautilus CC Plus 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.
