Buy Dolphin QuantumAquabot X4 or Dolphin T3000: our take
Aquabot X4 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. Aquabot X4 is rated for pools up to 60 ft; Dolphin T3000 is rated up to 50 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Aquabot X4 lists 1 active brush and Intelligent navigation. Dolphin T3000 lists 2 active brushes and CleverClean navigation.
Filtration and debris
Aquabot X4 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
Aquabot X4 provides a weekly timer; Dolphin T3000 provides a weekly timer and smartphone control. Aquabot X4 uses a 60 ft corded cable with an anti-tangle swivel, while Dolphin T3000 uses continuous corded power. Aquabot X4 is listed at 40 lb versus 17.9 lb for Dolphin T3000; that 22.1 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Aquabot X4 is listed at $747 and Dolphin T3000 at $1,449; Aquabot X4 is $702 less. Aquabot X4 lists a 2-year warranty compared with 3 years for Dolphin T3000. Aquabot X4 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.
