When it comes to maintaining a pristine swimming environment, few brands match the engineering excellence and innovation of Maytronics Dolphin robotic pool cleaners. Among their top contenders for in-ground pool maintenance are the Dolphin Nautilus CC Pro vs the Dolphin Quantum—two sophisticated models tailored for high-efficiency cleaning. Both offer advanced navigation, wall-climbing abilities, and fine filtration systems, yet each takes a unique approach to navigation, debris handling, and user control.
In this comprehensive comparison, we explore every critical specification and user-experience detail, examining how these two robotic cleaners stack up across multiple categories including pool coverage, filtration, scrubbing ability, smart features, and handling efficiency. This in-depth breakdown will help pool owners choose the model that offers the most effective, convenient, and future-proof cleaning experience.

Differences Between Dolphin Nautilus CC Pro vs Dolphin Quantum
Below is a summary of the specifications:
The Dolphin Nautilus CC Pro and Dolphin Quantum are both designed for in-ground pools up to 50 feet in length and offer full coverage of pool floors, walls, and the waterline. However, their navigation systems differ in complexity and performance.
The Nautilus CC Pro uses CleverClean™ navigation, a smart algorithm that scans the pool and maps a cleaning path based on pre-programmed logic. While effective for most rectangular and oval pools, it lacks real-time adjustment capabilities, which can slightly impact efficiency in pools with unique features or heavy debris.
The Dolphin Quantum, on the other hand, features SmartNav 2.0™ with integrated gyroscopic steering, allowing it to maintain precise orientation during cleaning. This results in fewer missed spots, better wall tracking, and more efficient coverage, especially in irregularly shaped pools or those with complex surfaces.
Winner: Dolphin Quantum
With gyroscopic steering and adaptive scanning, the Quantum offers more precise and consistent navigation throughout the entire pool.
Filtration System and Debris Management
The Nautilus CC Pro features a top-load filter basket that incorporates both fine and ultra-fine mesh layers, delivering effective filtration for common pool debris including dust, silt, pollen, and small leaves. It’s easy to remove and rinse, making it a favorite for convenience-minded users.
The Quantum is equipped with oversized dual-cartridge filters, positioned for top-load access as well. These ultra-fine filters have a higher total capacity and provide excellent water polishing, capturing even the smallest particulates while maintaining strong water flow. The larger volume also means fewer clean-outs during peak debris seasons.
Winner: Dolphin Quantum
Its larger filter cartridges provide better filtration efficiency and longer intervals between cleanings.
Brush Design and Scrubbing Effectiveness
The Dolphin Nautilus CC Pro uses dual active scrubbing brushes that rotate independently at higher speeds than the cleaner’s movement, ensuring deep contact and effective dirt removal. Positioned at the front, these brushes are optimized for general grime, algae, and surface biofilm.
The Quantum features proprietary HyperBrush™ dual scrubbers, rotating at twice the speed of standard brushes. Their faster rotation and non-slip material give the Quantum superior scrubbing power, especially for stubborn contaminants, algae buildup, and rougher pool surfaces.
Winner: Dolphin Quantum
With faster HyperBrushes and stronger rotational torque, the Quantum scrubs more aggressively across a wider variety of pool surfaces.
Waterline Cleaning and Vertical Climbing
Both cleaners include vertical climbing capabilities and are rated for waterline cleaning, a crucial task for removing scum, sunscreen oils, and floating debris that collect at the tile line.
While the Nautilus CC Pro performs this task competently, its climbing stability relies heavily on surface type and water conditions. It may need multiple cycles to fully complete waterline coverage in certain pools.
The Quantum, equipped with continuous rubber tracks and gyroscopic balance, maintains superior vertical positioning and adheres more consistently to the tile line. It scrubs with force and stability along the entire waterline perimeter during every cycle.
Winner: Dolphin Quantum
Better climbing grip and enhanced wall stability ensure more effective and consistent waterline cleaning.
Smart Features and User Control
The Dolphin Nautilus CC Pro stands out with its Bluetooth connectivity, allowing it to sync with the MyDolphin Plus App. Users can remotely start and stop cleaning cycles, select between Quick and Standard cleaning modes, and set a weekly scheduler through their smartphone.
The Dolphin Quantum, by contrast, does not include app support or Wi-Fi/Bluetooth capabilities. It operates on a fixed 2-hour cycle that starts with a manual button press. There is no option for scheduling or remote operation.
Winner: Dolphin Nautilus CC Pro
Its app integration and flexible control options make it a smarter choice for modern pool owners seeking automation.
Cable Design and Tangle Prevention
Both units use a 60-foot cable, which is sufficient for most residential pool sizes. However, neither model features a swivel mechanism, meaning both rely on internal software pathing and physical design to prevent tangling during operation.
The Quantum’s gyroscopic navigation and more accurate steering help it reduce cable twisting over time, while the Nautilus CC Pro’s CleverClean system, although efficient, may result in more overlap and occasional twists in pools with more complex layouts.
Winner: Dolphin Quantum
With smoother directional control, it reduces drag and cable tension during long cleaning sessions.
Handling, Portability, and Storage
The Nautilus CC Pro weighs approximately 19 lbs, making it one of the more portable full-featured robotic pool cleaners in the Dolphin range. Its compact size and ergonomic design make retrieval and manual storage relatively easy.
The Quantum, weighing around 22 lbs, feels more robust and stable in the water but is slightly heavier to lift manually. Both models offer optional caddies for easy storage and transportation, though these are sold separately.
Winner: Dolphin Nautilus CC Pro
Its lighter weight and compact build give it an edge in handling and portability.
