Differences Dolphin Nautilus CC Plus vs Dolphin Quantum
Below is a summary of the specifications:
Cleaning Coverage and Pool Surface Reach
The Dolphin Nautilus CC Plus WiFi is tailored for in-ground pools up to 50 feet, with advanced CleverClean navigation and a built-in gyroscope. It is engineered to clean floors and walls efficiently, following intelligent mapping that minimizes redundant paths. The gyroscopic scanning enhances directional stability, ensuring more accurate wall climbs and edge transitions.
The Dolphin Quantum, on the other hand, is also designed for in-ground pools up to 50 feet, but it includes dedicated waterline cleaning. Powered by SmartNav 2.0, it maps out the pool in greater detail and uses gyroscopic sensors to ensure full-floor, wall, and waterline coverage. This makes it ideal for homeowners who notice persistent grime at the surface edge.
Winner: Dolphin Quantum
With its inclusion of waterline cleaning and superior mapping capability, the Quantum provides more comprehensive pool surface coverage.
Filtration and Debris Capacity
The Nautilus CC Plus WiFi uses a dual-layer filtration system, combining fine and ultra-fine cartridges. These filters are top-loading, easy to remove, and exceptionally efficient at capturing both large debris and fine particles like sand, pollen, and algae. It ensures consistently clear pool water with minimal maintenance.
The Quantum features an extra-large fine filter basket with a high debris capacity. While it can handle significant leaf loads and large debris, it lacks a built-in ultra-fine layer, making it less efficient at capturing the smallest particles unless additional filter upgrades are installed. However, its oversized design means fewer cleanouts are required.
Winner: Dolphin Nautilus CC Plus WiFi
For fine filtration performance and water polishing, the dual-layer system of the CC Plus WiFi is superior. It provides better micro-debris capture right out of the box.
Brush Technology and Cleaning Effectiveness
The Nautilus CC Plus WiFi comes equipped with dual active brushes, which rotate at high speeds to agitate and scrub pool surfaces, effectively removing stubborn dirt and biofilm from floors and walls.
The Quantum steps this up with HyperBrush™ technology, a proprietary high-speed dual brush system that rotates twice as fast as standard brushes. This aggressive scrubbing action, combined with waterline capability, enables the Quantum to target algae and sticky grime in harder-to-reach areas.
Winner: Dolphin Quantum
With faster rotation and wider coverage, the Quantum’s HyperBrush system offers more advanced and aggressive cleaning, especially for pools with persistent algae or surface buildup.
The Nautilus CC Plus WiFi employs CleverClean Navigation, guided by a gyroscopic sensor. It efficiently maps out pool surfaces and follows optimized cleaning routes, ensuring thorough floor and wall cleaning with minimal path overlap.
The Quantum uses SmartNav 2.0, a more evolved navigation engine that combines gyroscopic data with real-time obstacle sensing. This allows it to adjust course mid-cycle and cover tricky layouts with more agility and intelligence. Its ability to focus on corners, walls, and waterlines is a significant advantage.
Winner: Dolphin Quantum
Thanks to real-time adjustment and enhanced edge detection, the Quantum delivers more adaptive and precise navigation.
App Connectivity and User Convenience
The Nautilus CC Plus WiFi supports MyDolphin Plus App, offering full smartphone control. Users can start, stop, and schedule cleaning sessions remotely, monitor status, and customize cycles with ease. This functionality is ideal for tech-savvy homeowners or those managing rental or secondary homes.
The Quantum lacks any form of app or WiFi connectivity. All operations must be initiated manually through its power supply. It has no weekly scheduler and no way to interact with the cleaner remotely, limiting convenience.
Winner: Dolphin Nautilus CC Plus WiFi
With seamless remote access and automation via app, it provides a more user-friendly, set-it-and-forget-it experience.
Cable Type and Movement Flexibility
Both the Nautilus CC Plus WiFi and the Quantum feature a 60-foot swivel cable, which prevents tangling during cleaning cycles and supports full pool coverage. This design ensures smooth turns and fewer interruptions, regardless of pool size or shape.
The Quantum, despite being heavier, maneuvers surprisingly well due to its internal propulsion system and side-release water expulsion that aids turning and directional changes. Still, the benefits of the swivel cable are equally present in both models.
Winner: Tie
Both cleaners offer excellent cable mobility with anti-tangle technology, ensuring consistent movement across the pool.
Weight and Handling
The Nautilus CC Plus WiFi weighs 19 lbs, making it manageable for most users to lift out of the pool after cleaning. It has a well-balanced frame and integrated handle for ergonomic handling.
The Quantum, due to its larger body and increased internal components, weighs 27 lbs. While this heavier build contributes to its scrubbing power and larger debris basket, it can be more challenging to retrieve, especially when full of water.
Winner: Dolphin Nautilus CC Plus WiFi
Its lighter build makes it easier to handle, transport, and store, especially for solo users.
Warranty and Long-Term Durability
The Nautilus CC Plus WiFi is backed by a 2-year warranty, covering parts and labor for residential use. It features a rugged construction with high-grade plastic housing and durable internals engineered for regular weekly operation.
The Quantum includes a longer 2.5-year warranty, reflecting its premium build quality and slightly more commercial-grade components. Its exterior shell and drivetrain are reinforced for longevity, especially under heavy use conditions.
Winner: Dolphin Quantum
With a longer warranty and upgraded structural integrity, it stands out as the more durable long-term investment.

Conclusion
Choose Dolphin Nautilus CC Plus WiFi if you value smart features, remote control, excellent filtration, and a lighter, user-friendly design. It’s ideal for tech-savvy users who want a connected pool cleaner that can be managed from anywhere, especially for standard in-ground pools that don’t require waterline cleaning.
Choose Dolphin Quantum if your priority is deep scrubbing performance, larger debris capacity, full waterline cleaning, and extended durability. It’s better suited for pools that collect heavy debris, require stronger scrubbing, and benefit from thorough surface coverage, even without the convenience of app-based control.
Overall Winner: Dolphin Quantum
With waterline cleaning, HyperBrush technology, SmartNav 2.0, and enhanced durability, the Dolphin Quantum delivers the most complete and powerful cleaning performance in its class. While the Nautilus CC Plus WiFi shines with smart convenience, the Quantum dominates in deep-cleaning capability and long-term value.
