Buy Dolphin QuantumDolphin Active 2000 or Dolphin Explorer E40: our take
Dolphin Active 2000 and Dolphin Explorer E40 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 Active 2000 is intended for inground and above-ground pools, while Dolphin Explorer E40 is intended for inground pools. Dolphin Active 2000 is rated for pools up to 40 ft; Dolphin Explorer E40 is rated up to 50 ft. Dolphin Active 2000 cleans floor, walls, and waterline; Dolphin Explorer E40 cleans floor. Dolphin Active 2000's documented cleaning system includes 2 active brushes and CleverClean navigation.
Filtration and debris
Dolphin Active 2000 has documented included filtration—Basket and UltraFilter—while the other model's included media is not fully published. That gives Dolphin Active 2000 the clearer documented edge for fine silt, pollen and sand. Dolphin Active 2000 also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin Active 2000 provides a weekly timer and smartphone control; Dolphin Explorer E40 provides no fully published timer, app or remote specification.
Price, warranty and the decision
Dolphin Active 2000 is listed at $1,199 and Dolphin Explorer E40 at $1,599; Dolphin Active 2000 is $400 less. Dolphin Active 2000 lists a 2-year warranty compared with 3 years for Dolphin Explorer E40. Dolphin Active 2000 and Dolphin Explorer E40 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.
