Buy Dolphin QuantumDolphin Explorer E70 or Dolphin Nautilus CC Supreme: our take
Dolphin Explorer E70 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
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 Explorer E70 lists CleverClean navigation. Dolphin Nautilus CC Supreme lists 2 active brushes and CleverClean navigation.
Filtration and debris
Dolphin Explorer E70 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 Explorer E70 also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Both models provide a weekly timer, smartphone control, and included remote control. Both use a 60 ft corded cable with an anti-tangle swivel.
Price, warranty and the decision
Dolphin Explorer E70 is listed at $2,099 and Dolphin Nautilus CC Supreme at $1,599; Dolphin Nautilus CC Supreme is $500 less. Each lists a 3-year manufacturer warranty. Dolphin Explorer E70 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.
