Buy Dolphin QuantumDolphin Premium 30 or Dolphin Proteus DX3: our take
Dolphin Premium 30 and Dolphin Proteus DX3 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

Controls and day-to-day ownership

Dolphin Premium 30 is listed at 18.4 lb versus 14 lb for Dolphin Proteus DX3; that 4.399999999999999 lb difference matters when lifting the robot from the pool.
