Buy Dolphin QuantumDolphin Liberty 600 or Dolphin Nautilus CC Plus: our take
Dolphin Liberty 600 and Dolphin Nautilus CC Plus 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 Liberty 600 cleans floor, walls, and waterline; Dolphin Nautilus CC Plus cleans floor and walls. Dolphin Nautilus CC Plus's documented cleaning system includes 2 active brushes and CleverClean navigation.
Filtration and debris
Dolphin Liberty 600 includes Basket and UltraFilter; Dolphin Nautilus CC Plus includes Standard filter. That gives Dolphin Liberty 600 the clearer documented edge for fine silt, pollen and sand. Dolphin Liberty 600 also 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 Liberty 600 uses cordless battery power, while Dolphin Nautilus CC Plus uses a 60 ft corded cable with an anti-tangle swivel. Dolphin Liberty 600 is listed at 25.8 lb versus 20 lb for Dolphin Nautilus CC Plus; that 5.800000000000001 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Liberty 600 is listed at $1,729 and Dolphin Nautilus CC Plus at $949; Dolphin Nautilus CC Plus is $780 less. Dolphin Liberty 600 lists a 3-year warranty compared with 2.5 years for Dolphin Nautilus CC Plus. Dolphin Liberty 600 and Dolphin Nautilus CC Plus 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.
