Buying guidance

Dolphin EON 100 or Dolphin T45: our take

Dolphin EON 100 and Dolphin T45 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 EON 100 is intended for inground and above-ground pools, while Dolphin T45 is intended for inground 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 lists SmartMap navigation. Dolphin T45 lists CleverClean navigation.

Filtration and debris

Dolphin EON 100 includes Basket; Dolphin T45 includes Basket and UltraFilter. Dolphin T45 has the clearer documented edge for fine silt, pollen and sand.

Controls and day-to-day ownership

Both models provide a weekly timer and smartphone control. Dolphin EON 100 uses cordless battery power, while Dolphin T45 uses a 60 ft corded cable with an anti-tangle swivel.

Price, warranty and the decision

Each lists a 2-year manufacturer warranty. Dolphin EON 100 and Dolphin T45 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.
