When evaluating premium robotic pool cleaners for in-ground pools, two models in the Dolphin lineup rise to the top: the Dolphin Nautilus CC Plus vs Dolphin Nautilus CC Supreme. These high-performance machines are built to deliver intelligent, deep-cleaning automation while reducing the time and effort required for manual pool maintenance.
Although they share many similarities in brand design and reliability, their feature sets, capabilities, and technological enhancements place them in different tiers. In this detailed comparison, we explore each aspect that separates the Nautilus CC Plus WiFi from the more advanced CC Supreme, helping pool owners make the most informed decision for their cleaning needs.

Differences Dolphin Nautilus CC Plus vs Dolphin Nautilus CC Supreme
Below is a summary of the specifications:
Cleaning Coverage and Capability
The Dolphin Nautilus CC Plus WiFi is designed for floor and wall cleaning, utilizing dual active brushes and a precise scanning algorithm to navigate pool surfaces efficiently. It handles in-ground pools up to 50 feet and delivers consistent results over flat, angled, or slightly curved walls.
The Dolphin Nautilus CC Supreme surpasses this by offering complete floor, wall, and waterline coverage. Equipped with SmartNav 3.0 navigation and triple scrubbing brushes, the CC Supreme thoroughly cleans every inch of the pool surface—including the often-neglected scum line at the water’s edge.
Winner: Dolphin Nautilus CC Supreme
With enhanced navigation, stronger scrubbing capability, and full waterline cleaning, the Supreme is better suited for users demanding a deep, all-surface clean.
Filtration System and Debris Capacity
The CC Plus WiFi features a dual-cartridge top-load filter system that separates fine and ultra-fine debris, effectively capturing leaves, sand, algae, and small particles. The cartridges are easy to rinse and reinstall.
In contrast, the CC Supreme uses a multi-layer filtration basket that combines a large debris chamber with both fine and ultra-fine mesh levels in one high-capacity unit. This design handles larger debris loads with fewer cleanouts and maintains high suction power throughout the cleaning cycle.
Winner: Dolphin Nautilus CC Supreme
Its larger debris basket and integrated multi-stage filtering provide more effective and lower-maintenance debris management, especially in high-debris pools.
Brush Configuration and Scrubbing Power
The Nautilus CC Plus WiFi is equipped with two high-speed active brushes, which rotate independently to remove dirt and grime from the pool’s floor and walls. This system provides strong contact and effective scrubbing but is limited in surface coverage speed and variety.
The Nautilus CC Supreme takes this further with three active brushes—two in the front and one in the rear. This triple-brush configuration enables simultaneous scrubbing across multiple surfaces and angles, making it exceptionally effective at tackling algae buildup, scale, and difficult-to-clean edges.
Winner: Dolphin Nautilus CC Supreme
With an extra brush and broader mechanical coverage, the Supreme offers unmatched scrubbing intensity and speed.

Cycle Customization and Cleaning Control
The CC Plus WiFi operates on a fixed 2-hour cycle, which is well-optimized for most standard in-ground pools. The cycle duration is not adjustable, and while it performs efficiently, users don’t have the flexibility to customize based on immediate needs.
The CC Supreme offers three distinct cleaning cycles: 1.5, 2, and 2.5 hours, allowing pool owners to tailor the cleaning duration depending on pool conditions. Whether it’s a quick touch-up or a full intensive clean, the cycle customization offers adaptability and control.
Winner: Dolphin Nautilus CC Supreme
Cycle options deliver greater user flexibility and operational efficiency depending on usage frequency and pool condition.
The Nautilus CC Plus WiFi uses CleverClean navigation with a built-in gyroscope, enabling accurate mapping and obstacle avoidance. It scans the pool layout and follows a logical cleaning path to avoid wasted motion.
The CC Supreme enhances this with SmartNav 3.0, an upgraded navigation platform that uses gyroscopic and onboard sensor feedback in real time. It adapts dynamically to the pool shape, redirects when encountering resistance, and achieves better coverage consistency in complex pool layouts.
Winner: Dolphin Nautilus CC Supreme
SmartNav 3.0 provides a more refined navigation experience, covering tricky contours and reaching neglected corners with greater accuracy.
App Integration and Remote Features
Both models are compatible with the MyDolphin Plus App, allowing users to start or stop cleanings, set a weekly schedule, and monitor activity from their smartphone. However, the CC Supreme’s Premium app experience adds more detailed status feedback, custom cycle selection, and enhanced control responsiveness.
Additionally, the CC Supreme includes Lift-Out Assist, a premium feature that brings the robot to the waterline for easier retrieval after cleaning. The CC Plus WiFi does not have this function, requiring manual location and lifting from deeper water.
Winner: Dolphin Nautilus CC Supreme
With a more complete app experience and added post-cleaning convenience, the Supreme stands out for smart feature integration.

Cable Management and Handling
Both units are fitted with a 60-foot tangle-free swivel cable, supporting full mobility in large pools without coiling issues. This design allows both cleaners to work uninterrupted for their full cleaning duration and helps users avoid downtime from tangled cords.
Despite their shared cable architecture, the CC Supreme’s mobility is enhanced by more responsive motor control and better edge transitions, ensuring smoother operation and quicker repositioning during edge-to-edge cleaning.
Winner: Tie
While both offer excellent cable flexibility, the Supreme’s enhanced movement marginally improves operational fluidity.
Weight and Ergonomics
The CC Plus WiFi weighs 19 lbs, making it relatively lightweight and easy for most users to manage. It’s portable enough for weekly use without back strain and features an ergonomic carry handle for transport.
The CC Supreme, with its additional components and larger basket, weighs 24 lbs. However, its Lift-Out Assist feature offsets this weight, making removal from the pool considerably easier despite its heavier frame.
Winner: Dolphin Nautilus CC Supreme
Although heavier, Lift-Out Assist improves usability and ensures convenient handling post-cleaning.
Warranty and Build Quality
The Nautilus CC Plus WiFi comes with a 2-year warranty, providing dependable protection for residential pool use. It’s constructed with robust materials suitable for daily or weekly operation across multiple swim seasons.
The CC Supreme offers a longer 3-year warranty, reflecting its higher-tier motor, structural reinforcements, and more durable internal mechanisms. Designed for rigorous, frequent use, the CC Supreme is the better long-term investment for high-demand users.
Winner: Dolphin Nautilus CC Supreme
With stronger warranty backing and reinforced build components, the Supreme excels in long-term value and reliability.
