In the competitive world of robotic pool cleaners, few models offer the balance of performance, durability, and intelligent automation like the Dolphin Nautilus CC Plus vs Dolphin Proteus DX4. Both engineered by Maytronics, these cleaners are among the most trusted options for in-ground pool owners seeking convenience and thorough cleaning without the high-end price tag of commercial-grade units. However, despite their similarities in size and brand reputation, their differences in connectivity, cleaning control, debris handling, and smart features make each model uniquely suited to different pool needs.
This in-depth comparison explores every functional detail between the Nautilus CC Plus WiFi and the Proteus DX4, revealing which robotic pool cleaner offers superior value and long-term performance for residential pools.

Differences Dolphin Nautilus CC Plus vs Dolphin Proteus DX4
Below is a summary of the specifications:
Both the Nautilus CC Plus WiFi and the Proteus DX4 are optimized for in-ground pools up to 50 feet, offering full coverage of the floor and walls. Each utilizes CleverClean navigation, Maytronics’ intelligent scanning algorithm that ensures efficient cleaning paths and reduced overlap. However, there are key distinctions in navigation refinement and movement logic.
The Nautilus CC Plus WiFi includes a gyroscope-enhanced navigation system, allowing it to more accurately detect orientation, maintain consistent wall contact, and optimize pathing across pool surfaces. This results in smoother transitions, fewer missed zones, and a more polished overall clean.
The Proteus DX4, while still efficient, uses a more basic version of CleverClean without gyroscopic correction. In pools with unusual shapes or slope changes, it may struggle with navigation precision and consistency compared to the CC Plus WiFi.
Winner: Dolphin Nautilus CC Plus WiFi
With gyroscopic assistance, the CC Plus WiFi delivers a more refined and efficient cleaning experience across complex pool geometries.
Filter Type and Debris Handling Capacity
The Nautilus CC Plus WiFi is equipped with a dual-layer top-loading cartridge system, separating fine and ultra-fine debris for maximum filtration precision. This setup traps sand, algae, silt, leaves, and even pollen efficiently, maintaining cleaner water clarity and requiring fewer filter rinses in most conditions.
The Proteus DX4 uses a single-layer fine filter basket, which performs well for medium-sized debris such as leaves and dirt but lacks the secondary ultra-fine mesh required to capture micro-particles or suspended matter. While easy to access and clean, it doesn’t offer the same level of detailed water polishing.
Winner: Dolphin Nautilus CC Plus WiFi
Its advanced two-stage filtration ensures cleaner water with higher efficiency in fine particle capture.
Brush Performance and Surface Scrubbing
Both cleaners come with dual brushes, but the Nautilus CC Plus WiFi features active brushes, which rotate independently at higher speeds than the movement of the unit itself. This delivers better friction against algae and biofilm, particularly on smooth plaster, tile, or vinyl surfaces.
The Proteus DX4, in comparison, uses standard dual brushes, which provide decent contact but lack the aggressive action of active rotation. As a result, the CC Plus WiFi performs better when dealing with slippery buildup or seasonal algae.
Winner: Dolphin Nautilus CC Plus WiFi
Its high-speed active brushes provide more thorough scrubbing and reduce manual brushing needs.
App Control and Smart Connectivity
The Nautilus CC Plus WiFi offers full WiFi connectivity through the MyDolphin Plus App, one of its most distinctive advantages. Users can remotely start and stop cycles, schedule weekly cleanings, monitor cleaning status, and receive alerts from any location using their smartphone. This enables true autonomous cleaning management, particularly helpful for vacation homes or weekly pool care routines.
The Proteus DX4, in contrast, lacks any form of app control or digital scheduling. Users must manually start each cleaning session, and there’s no remote interface or programmable timer, limiting convenience and long-term automation.
Winner: Dolphin Nautilus CC Plus WiFi
With app-based control and smart scheduling, it offers a significantly more modern and user-friendly experience.
Cable and Maneuverability
Both models include a 60-foot power cable, but only the Nautilus CC Plus WiFi features a tangle-free swivel, which allows the robot to turn freely without cable twists. This is especially important in larger pools where the robot needs to cover wide areas without interruptions.
The Proteus DX4’s standard floating cable may tangle or coil over time, particularly during long cleaning sessions or repeated wall climbs. Users may need to manually adjust or untangle the cord periodically to maintain optimal cleaning coverage.
Winner: Dolphin Nautilus CC Plus WiFi
Its swivel cable ensures uninterrupted cycles and less maintenance during and after cleaning sessions.
Cycle Duration and Cleaning Control
Both units operate on a 2-hour cycle, which is sufficient for most standard in-ground pool sizes. The Nautilus CC Plus WiFi allows users to schedule this cycle at preferred intervals through the app—daily, every other day, or every three days—making it ideal for hands-free maintenance.
The Proteus DX4, while consistent in its 2-hour cleaning performance, offers no programmable scheduling. Each use requires manual activation, which can become inconvenient for those looking to automate their pool care routine.
Winner: Dolphin Nautilus CC Plus WiFi
Scheduling capability and remote access enhance usability and reduce user effort over time.
Waterline Cleaning Capability
Neither the Nautilus CC Plus WiFi nor the Proteus DX4 is equipped for dedicated waterline scrubbing. Both clean floors and walls, but stop just short of fully addressing the pool’s upper edge where oils, debris, and sunblock residues accumulate.
For users specifically needing waterline coverage, a model like the Dolphin Premier or M600 may be more appropriate. However, within this comparison, both units are equal in this regard.
Winner: Tie
Neither model supports full waterline cleaning, but both handle floor and wall surfaces effectively.
Weight and Handling
The Nautilus CC Plus WiFi weighs 19 lbs, offering a good balance between build quality and portability. It features a top-mounted handle for simple retrieval, though lifting from deeper pools can require moderate effort.
The Proteus DX4 is lighter at 16.5 lbs, making it easier for users with physical limitations to remove and transport. This advantage makes it a bit more accessible for frequent manual handling, especially in smaller pools or for seasonal use.
Winner: Dolphin Proteus DX4
Its lighter frame improves ease of handling, especially for users who prefer frequent manual control.
Warranty and Build Durability
Both models are backed by a 2-year warranty, providing strong protection for residential use. Each is constructed with corrosion-resistant materials and weather-sealed motor components, ensuring years of reliable service under typical pool conditions.
Though similar in warranty length, the Nautilus CC Plus WiFi’s enhanced internal components—including gyroscopic sensors and advanced filter modules—provide more operational sophistication. This often translates to fewer mechanical issues under frequent use.
Winner: Dolphin Nautilus CC Plus WiFi
Its higher-grade internals and tech enhancements offer more robust long-term value.
