Buy Dolphin CaymanDolphin Echo or Dolphin Nautilus CC Plus: our take
Dolphin Echo 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 Echo 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 Echo lists 1 active brush and CleverClean navigation. Dolphin Nautilus CC Plus lists 2 active brushes and CleverClean navigation.
Filtration and debris
Dolphin Echo includes Basket; Dolphin Nautilus CC Plus includes Standard filter. Dolphin Echo also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin Echo provides one-touch starts and power-supply controls; Dolphin Nautilus CC Plus provides a weekly timer and smartphone control. Dolphin Echo uses continuous corded power, while Dolphin Nautilus CC Plus uses a 60 ft corded cable with an anti-tangle swivel. Dolphin Echo is listed at 14.8 lb versus 20 lb for Dolphin Nautilus CC Plus; that 5.199999999999999 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Echo is listed at $749 and Dolphin Nautilus CC Plus at $949; Dolphin Echo is $200 less. Dolphin Echo lists a 2-year warranty compared with 2.5 years for Dolphin Nautilus CC Plus. Dolphin Echo 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.
