The Zymurgoes Tune-Up Kit is a purpose-built replacement parts bundle for the Maytronics Dolphin Nautilus CC Plus robotic pool cleaner. This kit targets owners who want to restore their cleaner's peak performance without the hassle of sourcing individual parts. It is an excellent choice for maintaining a clean pool without professional help.
Standout features include both fine and ultra-fine filter cartridges, allowing the cleaner to trap everything from leaves and twigs to fine sand and dust. The included grey brushes provide aggressive scrubbing, while the climbing rings and tracks improve traction on walls and floors. Together, these parts significantly enhance debris collection and overall cleaning coverage.
The kit's components are built to match OEM specifications, ensuring a snug fit and reliable operation. The white color is standard and unobtrusive. Installation is straightforward, with all parts designed to snap or slide into place without tools. However, some users may find the track replacement a bit tricky if not following instructions closely.
A potential drawback is the limited compatibility: this kit only works with the Dolphin Nautilus CC Plus model. Additionally, while it covers the most common wear items, it does not include seals or internal parts that may also need replacement over time. Since no consumer reviews are available yet, long-term durability remains unverified.
Overall, the Zymurgoes Tune-Up Kit offers a convenient and cost-effective solution for maintaining a Dolphin Nautilus CC Plus. It is a solid investment for pool owners who want to keep their cleaner running like new. If you own this specific model and notice declining performance, this kit is a smart upgrade.
Pros
- Superior filtration from ultra fine pleated material, outperforming standard non-pleated filters.
- Durable ABS frame withstands regular use and chemical exposure without cracking.
- Cost-effective 4-pack reduces per-cartridge cost and frequency of replacement.
- Easy to clean and reuse, extending the life of each filter panel.
- Backed by a 1-year warranty for added confidence.
Cons
- Not compatible with older Nautilus CC, Nautilus (original), or Triton models; verify your robot before ordering.
- Some users may find the initial fit slightly snug in certain robot models, though it settles over time.
- Pleated filters may require more frequent rinsing in heavy-debris pools compared to coarse mesh options.
The SUNRRA Ultra Fine Filters are a versatile replacement option for a wide range of Dolphin robotic pool cleaners, including the Nautilus CC Plus, CC Supreme, M200, M400, M500, and many others. If you own one of these popular Maytronics models and want to improve water clarity, this 4-pack of pleated cartridges is a smart upgrade.
What sets these filters apart is their ultra fine pleated construction. Unlike standard non-pleated cartridges that let fine sediment slip through, the dense pleats trap even tiny particles like algae, pollen, and dust. The result is noticeably clearer pool water and a cleaner floor after each cycle. In real-world use, the filtration performance is excellent, especially for pools that struggle with cloudy water.
The build quality is solid: the frame is made from heavy-duty ABS plastic that resists cracking and tearing, even after repeated rinsing and seasonal storage. SUNRRA claims a lifespan of 2-3 years, which is reasonable if you clean them every 4-6 weeks. The 4-pack also means you have spares on hand, saving you from last-minute replacements.
One important note: these filters are not compatible with the original Nautilus CC, older Nautilus, or Triton series models. Always double-check your robot's model number before purchasing. Also, because the pleats are so fine, they may clog faster in pools with heavy leaf debris; you may need to rinse them more often than coarse mesh filters.
Overall, the SUNRRA Ultra Fine Filters offer excellent value for Dolphin owners who want premium filtration without paying premium prices. The 1-year warranty adds peace of mind, and the 4-pack ensures you're set for multiple seasons. If your robot is compatible, this is a highly recommended upgrade for crystal-clear pool water.
Pros
- Designed to replace Maytronics 9991432-R4 for many Dolphin robotic cleaner models
- Ultra fine pleated media traps both small particles and larger debris effectively
- Reinforced ABS frame keeps the filter stable during operation
- 4 pack provides good value and a longer interval before you need to reorder
- Simple maintenance with periodic rinsing every 4 to 6 weeks
Cons
- Not compatible with many Dolphin models such as Nautilus CC, M600, S200, Triton PS, and others, so check fit carefully before buying
- Aftermarket part is not an original Maytronics product, which may matter to some buyers
- No customer reviews are available yet, so long-term real-world performance is less proven
The Funmit M400 Ultra Fine Cartridge Filter is a 4 pack replacement designed for the Dolphin Nautilus CC Plus and a wide range of compatible robotic pool cleaners. It replaces Maytronics part 9991432-R4, making it a practical option for pool owners who want dependable filtration without the premium price of the OEM part.
The standout feature is the ultra fine pleated filter paper, which captures sand, leaves, hair, and other debris while maximizing surface area. The heavy duty ABS plastic frame keeps the pleats stable during operation and prevents the filter from deforming under water flow, so the cleaner maintains strong suction and consistent performance.
Maintenance is straightforward: rinsing the filter every 4 to 6 weeks is enough to keep it working well, and with proper care each filter can last 2 to 3 years. The 4 pack is especially convenient for owners who clean frequently or have a large pool, because there is always a fresh filter on hand.
The main drawback is compatibility. This filter does not fit several popular Dolphin models, including Nautilus CC, M600, S200, Triton PS, and others, so it is essential to verify your pool cleaner model before purchasing. As an aftermarket part, it also does not carry the original manufacturer branding, though the build quality is solid for the price.
Overall, the Funmit M400 filter replacement offers strong filtration, durable construction, and good value for owners of compatible Dolphin robotic cleaners. If you confirm the fit first, this 4 pack is a smart, budget friendly way to keep your pool clear all season.

Buying Guide
Filter Type: Fine vs. Ultra-Fine
Your Dolphin Nautilus CC Plus uses two filter types: fine panels (part 9991433-R4) for larger debris like leaves, and ultra-fine panels (part 9991432-R4) for capturing sand, silt, and microscopic particles. Many aftermarket sets include both, giving you flexibility. If your pool gets heavy organic matter, a fine filter handles the bulk load; if you want sparkling clarity, go ultra-fine. Some kits, like the one from Yoursme, provide both in a single tune-up package.
Compatibility and Fit
Not all filters labeled for the Nautilus CC Plus fit every model version. For instance, the original Nautilus CC (non-plus) uses different panels. Always confirm your cleaner’s exact model number and compare it to the listed compatible models. Brands like SUNRRA and Kerneed clearly state which units they support, including the Nautilus CC Supreme, M200, M400, and M500. Double check before buying to avoid returns.
Build Quality and Durability
Filter frames made from heavy-duty ABS plastic resist cracking and warping, even under constant water pressure. Pleated polyester media offers better dirt retention than flat mesh. Products like the Poolzilla ultra-fine filters and Funmit cartridges use reinforced pleats that hold their shape after repeated rinsing. A sturdy frame also ensures the filter stays seated during operation, preventing bypass. For tips on maintaining your cleaner’s traction, see our best pool robot traction brush.
Complete Tune-Up Kits vs. Standalone Filters
If your Nautilus CC Plus has been in service for more than a year, consider a tune-up kit that includes not only filters but also brushes, tracks, and climbing rings. Kits from Yoursme and Zymurgoes bundle all wear items, restoring scrubbing power and wall climbing ability. Standalone filter packs are cheaper and ideal if only the filters are worn. Assess your cleaner’s overall condition before deciding. For more on brush upgrades, read our best pool cleaner wall climbing brush.
Final Thoughts
After comparing all six options, we recommend the SUNRRA Ultra Fine Filters Compatible with Dolphin for pool owners who want a reliable, cost-effective upgrade that traps even the tiniest particles, and the for CC Plus Tune Up Rebuild Kit with 9991433-R4 for those needing a full refresh of brushes, tracks, and climbing rings to bring an older cleaner back to life. Both choices are validated for fit and performance, ensuring your Dolphin Nautilus CC Plus continues to deliver spotless results all season.

Frequently Asked Questions
How often should I replace the filters on my Dolphin Nautilus CC Plus?
With regular use, you should replace the filter panels every 6 to 12 months. However, if you notice reduced suction or debris left behind, swap them sooner. Rinsing the filters after each cleaning cycle extends their life. For a deeper look at robotic pool cleaner care, see our polaris freedom review.
Can I use both fine and ultra-fine filters together?
No, the Dolphin Nautilus CC Plus accepts only one set of filter panels at a time. You choose either fine or ultra-fine depending on your pool’s debris load. Some tune-up kits include both types so you can switch between them as needed.
Are these replacement filters compatible with the original Dolphin Nautilus CC (non-plus)?
Most aftermarket filters for the Nautilus CC Plus do not fit the original Nautilus CC. The CC Plus has a different filter housing. Always check the product description for explicit compatibility with your model. Brands like Poolzilla and SUNRRA clearly state if they are not compatible with the older Nautilus CC.
How do I clean the filters to maintain performance?
Rinse the filter panels with a garden hose after each cleaning cycle, focusing on the pleats to remove trapped debris. For stubborn dirt, use a soft brush. Avoid putting filters in a washing machine or using harsh chemicals. Proper rinsing every 4 to 6 weeks keeps them effective for months.
