- No battery worries, constant power means dependable cleaning cycles
- Simple maintenance with the top-load filter basket that traps leaves and debris
- Smart navigation helps ensure the entire pool gets covered without wasted movement

The Dolphin Proteus DX4 Plus is a corded robotic pool cleaner designed for in-ground pools up to 33 feet in length. It is a great choice for homeowners who want a hands-free cleaning solution that tackles not just the floor but also walls, waterline, steps, and sun ledges.
What sets this model apart is its continuous-power corded design. Unlike battery-powered robots that may stop for recharging, the Proteus DX4 Plus works consistently through the full cycle. The tangle-resistant cable helps prevent annoying twists, while the built-in smart navigation scans the pool to reduce missed spots and improve overall coverage.
Maintenance is straightforward thanks to the top-load filter basket. Leaves, dirt, and debris are captured in the large basket, and you can simply lift it out and rinse it with a garden hose. This makes it convenient to keep the cleaner ready for the next cycle without disassembling complex parts.
One trade-off is the lack of remote or app control; you depend on the automatic navigation pattern. Also, at 18.5 pounds, the unit is somewhat heavy to lift out of the pool, and the cord requires careful handling during setup. However, the robust build and reliable performance make these minor drawbacks acceptable for most pool owners.
Overall, the Dolphin Proteus DX4 Plus offers excellent value for anyone with a medium-sized in-ground pool who wants thorough, worry-free cleaning. It is especially suitable for those who prefer a corded robot for consistent power and easy filter maintenance over battery convenience.

Verdict: The Dolphin Nautilus CC Plus Wi-Fi is an excellent investment for pool owners who want a smart, self-cleaning robot.

Pros
- Significantly lower cost compared to OEM replacement cables.
- Includes useful accessories (floats and swivel) that enhance usability.
- Full 60-foot length works well in most residential pools.
- Simple plug-and-play installation with no modifications required.
Cons
- Not compatible with Nautilus CC Plus WiFi or Supreme models – double-check your robot version.
- Zero customer reviews available, so real-world reliability is unverified.
- Aftermarket part may have slightly different material quality vs. OEM.
The Gearwiz 9995862 is a 60-foot blue replacement cable designed for Dolphin Nautilus CC Plus (non-WiFi) and M200 pool robots. If your original cable is damaged, frayed, or just too short, this aftermarket option offers a practical and budget-friendly solution. It is important to note that this cable will not work with WiFi-enabled models or the Supreme version, so verify your robot's model before purchasing.
Standout features include the inclusion of two large floats and a swivel connector. The floats keep the cable riding on the water surface, preventing it from dragging along the pool floor and getting tangled. The swivel reduces the torque that builds up as the robot moves, which can extend the life of both the cable and the robot's connection port. The 60-foot length gives you ample reach for most inground pools, allowing the robot to clean without needing to move the power supply.
Build quality appears solid for an aftermarket part. The blue jacket is flexible yet durable, and the 2-prong connector fits snugly into the robot's socket. Installation is straightforward – simply unplug the old cable and plug in the new one. Gearwiz clearly states this is an aftermarket replacement and not affiliated with the original manufacturer, so you are getting a cost-effective alternative rather than a direct OEM copy.
One potential drawback is the lack of user reviews. Since there are no verified customer experiences, it is harder to gauge long-term durability or compatibility quirks. Additionally, the cable is not compatible with WiFi models, which may frustrate buyers who mistakenly purchase it. However, if you own the correct model, this cable should serve you well.
Verdict: The Gearwiz 9995862 is a solid choice for Dolphin Nautilus CC Plus (non-WiFi) and M200 owners who need a replacement cable. It offers good value, useful extras, and the right length for most pools. Just be sure to confirm your robot's model before ordering.
Buying Guide
Wall Climbing and Scrubbing Power
Both the Nautilus CC Plus and Proteus DX4 are designed to climb walls, but their scrubbing approaches differ. The Nautilus CC Plus uses an active scrubbing brush that adjusts to surfaces, ensuring thorough cleaning on tile, vinyl, and concrete. The Proteus DX4 also climbs walls and includes a waterline scrubber, which targets the scum line that often forms at the water’s surface. If your pool has persistent waterline buildup, the Proteus DX4’s dedicated scrubber is a clear advantage. For a deeper dive into wall-climbing performance, see our dolphin nautilus CC pro review.
Smart Navigation and Coverage
Smart navigation is where these two models diverge. The Nautilus CC Plus relies on a standard scanning system that moves the robot in a logical pattern, covering floors and walls efficiently. The Proteus DX4, on the other hand, features intelligent scanning that maps your pool’s shape and adjusts its path to reduce missed spots. This means the Proteus DX4 is better suited for irregularly shaped pools or those with many obstacles like steps and sun ledges. For a comparison of smart navigation across brands, read our dolphin vs hayward pool cleaner article.
Filtration and Maintenance
Both cleaners feature a top-load filter basket that is easy to remove and rinse, but the Nautilus CC Plus offers a slightly larger basket, which means fewer trips to the hose. The Proteus DX4 uses a fine filter that captures smaller particles, making it ideal for pools that collect fine debris like sand or pollen. If you prioritize convenience, the Nautilus CC Plus’s larger basket reduces maintenance frequency. For those who want the cleanest water possible, the Proteus DX4’s finer filtration is a better match. Explore more filter options in our ACCESSORIES category.
Connectivity and Convenience
The Nautilus CC Plus is available in both standard and Wi-Fi versions, allowing you to schedule cleanings from your phone. The Proteus DX4 does not offer Wi-Fi connectivity, so you must manually start each cycle. If you want to set and forget your pool cleaning schedule, the Wi-Fi version of the Nautilus CC Plus is the clear winner. However, if you prefer a simpler, plug-and-play approach without app dependencies, the Proteus DX4 remains a reliable choice. For a look at Wi-Fi enabled models, check out our dolphin proteus DX5i vs dolphin advantage pro comparison.
Final Thoughts
Choosing between the Dolphin Nautilus CC Plus and the Dolphin Proteus DX4 comes down to your pool’s specific needs and your desire for smart features. If you value Wi-Fi scheduling, a larger filter basket, and proven wall-climbing performance, the Dolphin Automatic Robotic Pool Vacuum Cleaner is your best bet. If you prioritize waterline scrubbing, intelligent navigation for complex pool shapes, and finer filtration, the Dolphin Proteus DX4 Plus Automatic Robotic Pool will serve you well. Both are backed by the Dolphin legacy of reliability, so whichever you choose, you are investing in years of hassle-free pool maintenance.
