Buy Dolphin EscapeDolphin Premium 10 or Niya Sonar Ray: our take
Dolphin Premium 10 and Niya Sonar Ray 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 Premium 10 is rated for pools up to 30 ft; Niya Sonar Ray is rated up to 26 ft. Each cleans floor, so coverage alone does not separate them. Dolphin Premium 10 lists 1 active brush and CleverClean navigation. Niya Sonar Ray lists Sonar navigation.
Filtration and debris
Both models include Basket.
Controls and day-to-day ownership
Both models provide one-touch starts and power-supply controls. Dolphin Premium 10 uses continuous corded power, while Niya Sonar Ray uses cordless battery power. Dolphin Premium 10 is listed at 14.6 lb versus 7.1 lb for Niya Sonar Ray; that 7.5 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Premium 10 is listed at $719 and Niya Sonar Ray at $199; Niya Sonar Ray is $520 less. Dolphin Premium 10 lists a 2-year warranty compared with 1 years for Niya Sonar Ray. Dolphin Premium 10 and Niya Sonar Ray each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Escape. Inground and above-ground pools up to 30 ft that need floor cleaning.
