Differences Between Dolphin Explorer E70 vs Dolphin Nautilus CC Supreme
Design Comparison
Both the Explorer E70 and the Nautilus CC Supreme are built for in-ground pools up to 50 feet in length and include a 60-foot tangle-free swivel cable, allowing the robot to maneuver smoothly without getting caught or twisted during extended cycles. The body design of the two is robust and hydrodynamic, meant for durability and stability underwater.
In terms of portability, the Nautilus CC Supreme is slightly lighter at 24.0 lbs compared to the Explorer E70’s 24.6 lbs, although the difference is barely noticeable in day-to-day use. Both units feature top-access filter compartments and ergonomic handles for lifting.
Winner: Tie
Both cleaners match evenly in terms of design for in-ground pools, cable length, and ease of use.
Cleaning Performance Comparison
The Explorer E70 delivers outstanding cleaning capability using dual front high-speed brushes and a powerful 5000 GPH suction motor. It excels at removing debris, algae, and fine sediment across floors, walls, and the waterline. The unit supports multi-layer filtration, combining fine and ultra-fine filters to trap both large and microscopic particles.
The Nautilus CC Supreme, on the other hand, employs an aggressive triple-brush system—two front brushes and an additional rear brush—which enhances surface contact and scrubbing effectiveness. It features a slightly lower 4500 GPH suction, but compensates with superior brushing coverage. Its dual filter cartridges also provide highly efficient debris separation and top-loading access.
Runtime on the E70 is adjustable between 1.5 to 2.5 hours, while the Nautilus CC Supreme supports cycles of 1.5, 2.5, or 3.5 hours, allowing for deeper cleaning when needed.
Winner: Dolphin Nautilus CC Supreme
With its triple-brush design and extended cycle options, the Nautilus CC Supreme offers more aggressive scrubbing and better adaptability for tougher pool conditions.
Feature Comparison
Both models include Wi-Fi connectivity and app control via the MyDolphin Plus app, offering remote control, scheduling, delay start, and real-time status updates. The Explorer E70 gains a slight edge with its Pick Me Up feature, which directs the robot to stop near the pool wall for easy retrieval—reducing strain during removal.
While the Nautilus CC Supreme does not include Pick Me Up, it does allow users to set longer cleaning cycles and offers equally strong scheduling and smart control capabilities. Both robots are compatible with weekly timers and respond well to app-based commands.
