Buy Dolphin EscapeDolphin Nautilus AG or Niya Sonar 10: our take
Dolphin Nautilus AG and Niya Sonar 10 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
Dolphin Nautilus AG is intended for above-ground pools, while Niya Sonar 10 is intended for inground and above-ground pools. Dolphin Nautilus AG is rated for pools up to 30 ft; Niya Sonar 10 is rated up to 20 ft. Each cleans floor, so coverage alone does not separate them. Dolphin Nautilus AG lists 1 active brush and CleverClean navigation. Niya Sonar 10 lists Dual drive motors.
Filtration and debris
Both models include Basket.
Controls and day-to-day ownership
Both models provide one-touch starts and power-supply controls. Dolphin Nautilus AG uses continuous corded power, while Niya Sonar 10 uses cordless battery power. Dolphin Nautilus AG is listed at 14.6 lb versus 7.1 lb for Niya Sonar 10; that 7.5 lb difference matters when lifting the robot from the pool.

Dolphin Nautilus AG is listed at $568 and Niya Sonar 10 at $149; Niya Sonar 10 is $419 less. Each lists a 1-year manufacturer warranty.
