Buy Dolphin CaymanDolphin Active Solo or Dolphin Echo: our take
Dolphin Active Solo and Dolphin Echo 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. Both are rated for pools up to 33 ft. Each cleans floor and walls, so coverage alone does not separate them. Dolphin Active Solo's documented cleaning system includes 1 active brush and CleverClean navigation.
Filtration and debris
Both models include Basket.
Controls and day-to-day ownership
Both models provide one-touch starts and power-supply controls. Both use continuous corded power. Dolphin Active Solo is listed at 14.6 lb versus 14.8 lb for Dolphin Echo; that 0.20000000000000107 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Active Solo is listed at $599 and Dolphin Echo at $749; Dolphin Active Solo is $150 less. Each lists a 2-year manufacturer warranty. Dolphin Active Solo and Dolphin Echo 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.
