Buy Dolphin QuantumDolphin Explorer E30 or Dolphin Nautilus CC Pro: our take
Dolphin Explorer E30 and Dolphin Nautilus CC Pro 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 pools. Both are rated for pools up to 50 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin Nautilus CC Pro's documented cleaning system includes CleverClean navigation.
Filtration and debris
Both models include Basket.
Controls and day-to-day ownership
Both models provide a weekly timer and smartphone control. Both use a 60 ft corded cable with an anti-tangle swivel.
Price, warranty and the decision
Dolphin Explorer E30 is listed at $1,099 and Dolphin Nautilus CC Pro at $1,199; Dolphin Explorer E30 is $100 less. Each lists a 2-year manufacturer warranty. Dolphin Explorer E30 and Dolphin Nautilus CC Pro 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.
