Differences Between Dolphin Explorer E20 vs Dolphin Nautilus CC Plus
Below is a summary of the specifications:
Design Comparison
The Dolphin Explorer E20 is compact and built for in-ground pools up to 33 feet, featuring a rugged shell, integrated carry handle, and balanced center of gravity that makes it easy to lift and transport. It weighs 16.5 pounds and includes a 50-foot non-swivel cable, which is sufficient for mid-sized pools. Its design favors simplicity, with a single active brush and a top-loading fine filter basket that makes routine debris removal easy.
In contrast, the Dolphin Nautilus CC Plus WiFi is a more robust unit built for in-ground pools up to 50 feet. It weighs 19 pounds, offering a sturdier design for deeper, larger pools. This model includes a 60-foot swivel cable, which helps prevent tangling during full-length pool coverage. Its wide body is anchored by dual scrubbing brushes and enhanced internal stability that allows for more aggressive vertical climbing, including waterline scrubbing.
Both models are well-constructed and ergonomic, but the CC Plus WiFi’s swivel cable and heavier-duty frame provide better handling in more expansive or heavily contoured pools.
Winner: Dolphin Nautilus CC Plus WiFi
With a longer cable, tangle-free design, and sturdier build for larger pools, the CC Plus WiFi takes the lead in design versatility and durability.

Cleaning Performance Comparison
The Explorer E20 delivers strong cleaning results for floor and wall surfaces, powered by a single active front brush and 4,000 GPH suction rate. Its CleverClean™ Navigation system efficiently maps the pool for optimized pathing and minimal overlap, completing a full cleaning cycle in 2 hours. While it climbs walls well, it does not perform waterline scrubbing, which limits its reach for pools prone to scum line buildup.
The Nautilus CC Plus WiFi takes pool coverage a step further. With dual scrubbing brushes, it aggressively agitates algae and debris from both flat and vertical surfaces. Its 4,500 GPH suction increases flow rate and debris intake, ensuring deeper cleaning during the same 2-hour runtime. Most notably, the CC Plus WiFi cleans the waterline, an area many mid-range cleaners leave untouched.
The filtration system in the E20 includes a top-load fine basket, easy to remove and rinse. The CC Plus WiFi uses a multi-layer system with both fine and ultra-fine filters, trapping everything from leaves to dust and sand particles, making it more effective in high-debris conditions.
Winner: Dolphin Nautilus CC Plus WiFi
Its enhanced suction, dual brushes, and full waterline scrubbing deliver a superior cleaning experience across all pool zones.

Feature Comparison
The Explorer E20 is a no-frills, plug-and-play cleaner. It relies solely on CleverClean™ Navigation for efficient pool coverage. There’s no Wi-Fi, app support, or automation—users simply plug in the power supply and press a button to begin each cleaning session. While this simplicity is ideal for users seeking ease of use, it lacks any advanced programmability or remote access.
The Nautilus CC Plus WiFi raises the bar with MyDolphin™ Plus App integration, giving users full remote control via smartphone. Through the app, you can:
- Start, pause, and stop cleanings
- Schedule daily or weekly cleaning routines
- Receive maintenance alerts and system updates
- Customize cleaning modes or delay cycles
This model also includes a weekly timer, allowing you to fully automate your pool care. It is designed for users who prefer a hands-off approach with flexible scheduling.
