Buying guidance

Dolphin Cayman or Dolphin Liberty 200: our take

Dolphin Cayman and Dolphin Liberty 200 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 Cayman has a published maximum pool length of 40 ft; the other model does not have a verified length in our source material. Each cleans floor and walls, so coverage alone does not separate them. Dolphin Cayman lists 1 active brush, SmartNav 2.0 navigation, and Dual 24-volt DC motors. Dolphin Liberty 200 lists Dual DC motors.

Filtration and debris

Dolphin Cayman includes MaxBin; Dolphin Liberty 200 includes Basket.

Controls and day-to-day ownership

Dolphin Cayman provides a weekly timer and power-supply controls; Dolphin Liberty 200 provides no fully published timer, app or remote specification. Dolphin Cayman uses a 50 ft corded cable, while Dolphin Liberty 200 uses cordless battery power.

Price, warranty and the decision

Dolphin Cayman is listed at $1,079 and Dolphin Liberty 200 at $999; Dolphin Liberty 200 is $80 less. Each lists a 2-year manufacturer warranty. Pool Express pick: Dolphin Cayman. Dolphin Cayman runs from continuous plug-in power without a recharge between cycles. Dolphin Cayman includes a 50 ft cable. Choose Dolphin Liberty 200 when it is the better fit for shoppers prioritizing the lower $999 starting price.
