Buy Dolphin QuantumDolphin EON 100 or Dolphin T3000: our take
Dolphin EON 100 and Dolphin T3000 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 50 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin EON 100 lists SmartMap navigation. Dolphin T3000 lists 2 active brushes and CleverClean navigation.
Filtration and debris
Dolphin EON 100 includes Basket; Dolphin T3000 includes Basket and UltraFilter. Dolphin T3000 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 T3000 uses continuous corded power. Dolphin EON 100 is listed at 22.1 lb versus 17.9 lb for Dolphin T3000; that 4.200000000000003 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin EON 100 lists a 2-year warranty compared with 3 years for Dolphin T3000. Dolphin EON 100 and Dolphin T3000 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.
