Buy Dolphin CaymanDolphin Nautilus CC or Dolphin Nautilus CC Plus: our take
Dolphin Nautilus CC 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 is rated for pools up to 33 ft; Dolphin Nautilus CC Plus is rated up to 50 ft. Each cleans floor and walls, so coverage alone does not separate them. Dolphin Nautilus CC lists 1 active brush. Dolphin Nautilus CC Plus lists 2 active brushes and CleverClean navigation.
Filtration and debris
Dolphin Nautilus CC includes Basket; Dolphin Nautilus CC Plus includes Standard filter. Dolphin Nautilus CC also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin Nautilus CC provides one-touch starts and power-supply controls; Dolphin Nautilus CC Plus provides a weekly timer and smartphone control. Dolphin Nautilus CC uses a 50 ft corded cable, while Dolphin Nautilus CC Plus uses a 60 ft corded cable with an anti-tangle swivel.
Price, warranty and the decision
Dolphin Nautilus CC is listed at $699 and Dolphin Nautilus CC Plus at $949; Dolphin Nautilus CC is $250 less. Dolphin Nautilus CC lists a 2-year warranty compared with 2.5 years for Dolphin Nautilus CC Plus. Dolphin Nautilus CC 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 Cayman. Inground and above-ground pools up to 40 ft that need floor and wall cleaning.
