Buying guidance

Dolphin EON 120d or Dolphin T60: our take

Dolphin EON 120d and Dolphin T60 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 120d is intended for inground and above-ground pools, while Dolphin T60 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 120d lists SmartMap navigation. Dolphin T60 lists 2 active brushes and CleverClean navigation.

Filtration and debris

Both models include Basket and UltraFilter. Both have documented fine-debris media, so basket capacity and ease of cleaning matter more than fine-particle capability.

Controls and day-to-day ownership

Both models provide a weekly timer and smartphone control. Dolphin EON 120d uses cordless battery power, while Dolphin T60 uses continuous corded power. Both are listed at 24.3 lb, so lifting effort is effectively the same.

Price, warranty and the decision

Each lists a 3-year manufacturer warranty. Dolphin EON 120d and Dolphin T60 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.
