Buy Dolphin QuantumDolphin Liberty 300 or Dolphin Nautilus CC Plus: our take
Dolphin Liberty 300 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. Dolphin Nautilus CC Plus 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 and walls, so coverage alone does not separate them. Dolphin Liberty 300 lists Dual DC motors. Dolphin Nautilus CC Plus lists 2 active brushes and CleverClean navigation.
Filtration and debris
Dolphin Liberty 300 includes Basket and UltraFilter; Dolphin Nautilus CC Plus includes Standard filter. That gives Dolphin Liberty 300 the clearer documented edge for fine silt, pollen and sand. Dolphin Liberty 300 also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin Liberty 300 provides no fully published timer, app or remote specification; Dolphin Nautilus CC Plus provides a weekly timer and smartphone control. Dolphin Liberty 300 uses cordless battery power, while Dolphin Nautilus CC Plus uses a 60 ft corded cable with an anti-tangle swivel.
Price, warranty and the decision
Dolphin Liberty 300 is listed at $1,099 and Dolphin Nautilus CC Plus at $949; Dolphin Nautilus CC Plus is $150 less. Dolphin Liberty 300 lists a 2-year warranty compared with 2.5 years for Dolphin Nautilus CC Plus. Dolphin Liberty 300 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.
