Buying guidance

Dolphin Advantage Ultra or Dolphin EON 100: our take

Dolphin Advantage Ultra and Dolphin EON 100 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

Dolphin Advantage Ultra is intended for inground pools, while Dolphin EON 100 is intended for inground and above-ground pools. Both are rated for pools up to 50 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin EON 100's documented cleaning system includes SmartMap navigation.

Filtration and debris

Both models include Basket.

Controls and day-to-day ownership

Dolphin Advantage Ultra provides a weekly timer and power-supply controls; Dolphin EON 100 provides a weekly timer and smartphone control. Dolphin Advantage Ultra uses a 60 ft corded cable with an anti-tangle swivel, while Dolphin EON 100 uses cordless battery power.

Price, warranty and the decision

Each lists a 2-year manufacturer warranty. Dolphin Advantage Ultra and Dolphin EON 100 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Quantum. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.

Dolphin Advantage Ultra vs Dolphin EON 100 specifications
