Buy Dolphin QuantumDolphin Active 2000 or Dolphin Nautilus CC Supreme: our take
Dolphin Active 2000 and Dolphin Nautilus CC Supreme 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 Nautilus CC Supreme is intended for inground pools. Dolphin Active 2000 is rated for pools up to 40 ft; Dolphin Nautilus CC Supreme is rated up to 50 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin Active 2000's documented cleaning system includes 2 active brushes and CleverClean navigation.
Filtration and debris
Dolphin Active 2000 includes Basket and UltraFilter; Dolphin Nautilus CC Supreme includes Standard filter and UltraFilter. Both have documented fine-debris media, so basket capacity and ease of cleaning matter more than fine-particle capability. 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 Nautilus CC Supreme provides a weekly timer, smartphone control, and included remote control. Dolphin Active 2000 uses continuous corded power, while Dolphin Nautilus CC Supreme uses a 60 ft corded cable with an anti-tangle swivel.
Price, warranty and the decision
Dolphin Active 2000 is listed at $1,199 and Dolphin Nautilus CC Supreme at $1,599; Dolphin Active 2000 is $400 less. Dolphin Active 2000 lists a 2-year warranty compared with 3 years for Dolphin Nautilus CC Supreme. Dolphin Active 2000 and Dolphin Nautilus CC Supreme 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.
