Buy Dolphin CaymanClear UV or Dolphin Nautilus AG: our take
Clear UV and Dolphin Nautilus AG 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
Clear UV is intended for inground pools, while Dolphin Nautilus AG is intended for above-ground pools. Clear UV is rated for pools up to 50 ft; Dolphin Nautilus AG is rated up to 30 ft. Clear UV cleans floor, walls, and waterline; Dolphin Nautilus AG cleans floor. Clear UV lists 2 active brushes, Intelligent navigation (C9 microprocessor), and Quad (2 pump + 2 drive) motors. Dolphin Nautilus AG lists 1 active brush and CleverClean navigation.
Filtration and debris
Clear UV includes UltraFilter; Dolphin Nautilus AG includes Basket. That gives Clear UV the clearer documented edge for fine silt, pollen and sand. Dolphin Nautilus AG has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Clear UV provides a weekly timer, smartphone control, and included remote control; Dolphin Nautilus AG provides one-touch starts and power-supply controls. Clear UV uses a 59 ft corded cable with an anti-tangle swivel, while Dolphin Nautilus AG uses continuous corded power. Clear UV is listed at 27.6 lb versus 14.6 lb for Dolphin Nautilus AG; that 13.000000000000002 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Clear UV is listed at $1,999 and Dolphin Nautilus AG at $568; Dolphin Nautilus AG is $1,431 less. Clear UV lists a 3-year warranty compared with 1 years for Dolphin Nautilus AG. Clear UV and Dolphin Nautilus AG 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.
