- Ultra-fine 10-micron filtration for superior water clarity
- Reusable and easy to clean with minimal maintenance
- Durable ABS construction lasts 2-3 years
- Fits multiple Dolphin and compatible pool cleaner models
- Backed by a 1-year warranty

The SUNRRA Ultra-Fine Filter Basket is a replacement part designed specifically for a wide range of Dolphin and compatible robotic pool cleaners. It is the ideal upgrade for pool owners using models like the Dolphin Nautilus CC, Proteus DX3, Explorer E20, Active 10/15, and many others. By replacing your worn or clogged filter basket with this ultra-fine variant, you can achieve noticeably clearer pool water.
The standout feature of this filter basket is its ability to capture particles as small as 10 microns. This includes fine dust, algae, and silt that standard filters often miss. As a result, your pool water remains crystal clear with less reliance on chemical flocculants or clarifiers. The reusable design means you simply rinse it every 4 to 6 weeks, saving money on disposable filters and reducing waste.
Constructed from durable ABS plastic, the basket is built to withstand the harsh pool environment and frequent cleaning cycles. SUNRRA claims a lifespan of 2 to 3 years with proper maintenance. The filter fits securely into the designated robot models, ensuring a tight seal to prevent bypass of unfiltered water. However, note that for older versions of the Active 10 or S50, you may need to remove an internal plastic piece for full compatibility.
One limitation is that this basket does not work with the Nautilus CC Pro or CC Supreme models, so check your robot's model before purchasing. Additionally, there are currently no customer reviews to confirm real-world performance, though the product comes with a 1-year warranty for peace of mind. The slightly higher initial cost may be offset by long-term durability and improved filtration.
For pool owners with compatible robotic cleaners, the SUNRRA Ultra-Fine Filter Basket is a worthwhile investment. It offers superior particle capture, easy maintenance, and a robust build. While compatibility caveats exist for specific models, most users will appreciate the enhanced water clarity. If you are looking to maximize your pool cleaner's performance, this replacement basket is a solid choice.

This part (9991460-R1) is ideal for pool owners seeking an affordable, high-performance alternative to the original filter. It is especially suited for those who want to improve water clarity by trapping fine particles without sacrificing cleaning efficiency.
The standout feature of this basket is its microfiltration technology, which captures small debris while allowing larger particles to pass through.

Installation is straightforward: it fits exactly like the original part, so no modifications or adapters are needed. Rinsing every 4-6 weeks keeps it working optimally, and with proper care, the basket can last 2-3 years, offering excellent value.
One potential drawback is that in extremely dirty pools, the filter may need more frequent rinsing to maintain flow. Additionally, the package includes only one basket, so owners of larger pools might need to buy a second. Also, while compatibility is broad, it does not cover every Dolphin model, so double-checking the list is wise. These are minor trade-offs for the price and performance.
Overall, the Fiitzn Ultra Fine Filtration Basket delivers on its promise of efficient fine debris capture and durability. It is a smart upgrade or replacement for Dolphin pool cleaner owners who want to keep their water crystal clear without breaking the bank. The combination of microfiltration, sturdy construction, and broad compatibility makes it a reliable choice for routine pool care.

The Gearwiz 99958821-60ft Blue Cable is an aftermarket replacement specifically engineered for the Dolphin Nautilus CC Plus WiFi pool robot. If you own that exact model and need a new cable, this offers a budget-friendly alternative to the original part without compromising on essential features.
Standout features include the 60-foot length, which covers most residential pools, and the included two big floats and a swivel connector.

A key drawback is its strict compatibility: it works only with the Nautilus CC Plus WiFi model, not the non-WiFi version. Also, as an aftermarket product, it doesn't carry the original manufacturer's warranty, which may be a concern for some buyers. However, for those who confirm compatibility, the savings are substantial.
Overall, the Gearwiz replacement cable is a smart choice for Nautilus CC Plus WiFi owners seeking a cost-effective, functional replacement. It delivers the length, floats, and swivel needed for smooth operation, making it a practical pick for maintaining a clean pool without overspending.
Pros
- Significantly lower cost compared to OEM replacement cables.
- Includes useful accessories (floats and swivel) that enhance usability.

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.
Dolphin Proteus DX3 vs Nautilus CC: Key Differences at a Glance
Both the Dolphin Proteus DX3 and the Dolphin Nautilus CC are popular choices for in-ground pools, but they cater to slightly different needs. The Proteus DX3 is known for its active scrubbing brush and wall-climbing power, while the Nautilus CC Plus offers Wi-Fi connectivity for smart scheduling. Let’s dive into the details.
If you’re looking for a robot that can handle tough dirt and debris, the Proteus DX3’s active scrubbing brush is a standout. On the other hand, if convenience is your priority, the Nautilus CC Plus Wi-Fi lets you control cleaning schedules from your smartphone. Both models are designed for pools up to 33-40 feet in length, so your pool size will also play a role in your decision.
Buying Guide: What to Consider Before Choosing
1. Cleaning Power and Wall Climbing
The primary job of any robotic pool cleaner is to scrub your pool’s floor, walls, and waterline. The Dolphin Proteus DX3 excels here with its active scrubbing brush, which aggressively removes algae and grime without damaging surfaces. It climbs walls efficiently, regardless of pool shape or surface type.
The Dolphin Nautilus CC Plus also offers wall-climbing capabilities, but it uses a standard scrubber brush. For pools with persistent algae or slippery surfaces, the active scrubbing technology of the Proteus DX3 gives it a clear edge. If you have a fiberglass or vinyl pool, both are gentle, but the Proteus DX3’s scrubbing action is more thorough.
2. Filtration System and Debris Handling
Both models use a top-load filter basket, which makes emptying debris easy. However, the type of filter you choose can significantly affect performance. The standard filter basket captures larger debris like leaves and twigs, while an ultra-fine filter basket is ideal for picking up fine particles like sand and dust.
If you have a pool that collects fine debris, you might want to consider an ultra-fine filter basket, such as the Ultra-Fine Filter Basket Part 9991460-r1, which is compatible with both the Proteus DX3 and Nautilus CC. These baskets can trap particles down to 10 microns, ensuring crystal-clear water. Remember to clean the filter every 4-6 weeks for optimal performance.
3. Smart Features and Convenience
In 2026, smart features are increasingly important. The Dolphin Nautilus CC Plus Wi-Fi allows you to schedule cleanings from anywhere via the Dolphin app. You can set a weekly timer, monitor cleaning cycles, and even receive notifications when the robot is done. This is a huge convenience for busy pool owners.
The Proteus DX3, on the other hand, is a plug-and-play model with a weekly timer on the power supply. While it lacks Wi-Fi, it still offers automated cleaning cycles. If you value app control, the Nautilus CC Plus is the way to go. For a more straightforward approach, the Proteus DX3 is simpler and reliable.
4. Power Supply and Cable Management
Both robots come with a power supply that includes a cable. The length of the cable is crucial, especially for larger pools. The Nautilus CC Plus includes a 60-foot cable, which is sufficient for pools up to 40 feet. The Proteus DX3 also comes with a similar cable, but if you need a replacement, you can find compatible options like the Gearwiz 9995861-60ft Blue Cable, which is designed for the Proteus DX3 (not the Nautilus).
Pay attention to the connector type. Some models use a 2-pin or 3-pin connector, and not all cables are interchangeable. Always verify compatibility before purchasing a replacement cable or power supply.
Final Thoughts
Choosing between the Dolphin Proteus DX3 and the Dolphin Nautilus CC ultimately comes down to your priorities. If you want aggressive cleaning with active scrubbing and don’t mind a manual approach, the Dolphin Proteus DX3 Automatic Robotic Pool Vacuum is a fantastic choice. If smart scheduling and Wi-Fi control are must-haves, the Dolphin Nautilus CC Plus Wi-Fi Automatic Robotic is worth the investment. Both deliver the legendary Dolphin reliability, so you can’t go wrong.
