Buying guidance

Dolphin Echo or Dolphin Nautilus Pool Up: our take

Dolphin Echo and Dolphin Nautilus Pool Up 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 Echo is rated for pools up to 33 ft; Dolphin Nautilus Pool Up is rated up to 30 ft. Each cleans floor and walls, so coverage alone does not separate them. Dolphin Echo lists 1 active brush and CleverClean navigation. Dolphin Nautilus Pool Up lists 1 active brush.

Filtration and debris

Dolphin Echo includes Basket; Dolphin Nautilus Pool Up includes Oversized leaf bag.

Controls and day-to-day ownership

Both models provide one-touch starts and power-supply controls. Dolphin Echo uses continuous corded power, while Dolphin Nautilus Pool Up uses a 40 ft corded cable. Dolphin Echo is listed at 14.8 lb versus 18 lb for Dolphin Nautilus Pool Up; that 3.1999999999999993 lb difference matters when lifting the robot from the pool.

Price, warranty and the decision

Dolphin Echo is listed at $749 and Dolphin Nautilus Pool Up at $499; Dolphin Nautilus Pool Up is $250 less. Each lists a 2-year manufacturer warranty. Dolphin Echo and Dolphin Nautilus Pool Up 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.
