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: What to Look for in a Dolphin Nautilus CC Replacement Filter
Compatibility with Your Specific Model
The most critical factor is ensuring the filter fits your exact Dolphin model. The Nautilus CC series includes the original Nautilus CC, Nautilus CC Plus, and Nautilus CC Supreme, each with different filter part numbers. Many aftermarket filters are designed for the CC Plus and Supreme but explicitly state they are not compatible with the original Nautilus CC. Always double-check the product description for model lists and part numbers like 9991432-R4 (ultra-fine) or 9991433-R4 (fine). For example, the SUNRRA and Funmit filters we reviewed are for CC Plus and Supreme, while the LBLVBNEWD basket fits older Nautilus CC models. If you own a different Dolphin robot, you might find our betta SE pool skimmer review helpful for surface debris management.
Filtration Efficiency: Ultra-Fine vs. Spring vs. Fine
Replacement filters come in three main types: ultra-fine pleated panels, spring (coarse) screens, and standard fine cartridges. Ultra-fine pleated filters, like those from Poolzilla and SUNRRA, capture tiny particles such as sand, silt, and algae spores, leaving the water crystal clear. Spring filters, such as the Kerneed set, use a screen material that traps larger debris like leaves and twigs without clogging quickly, ideal for the first few cleanings after a heavy storm. Fine filters (included in the Zymurgoes tune-up kit) offer a middle ground. For most pool owners, a set of ultra-fine filters provides the best all-around clarity, but having a spring set on hand can be useful during peak debris season.
Build Quality and Durability
The frame material and pleat construction determine how long the filter lasts. Look for heavy-duty ABS plastic frames that resist cracking and warping under water pressure. The pleated fabric should be dense yet washable, able to withstand repeated rinsing without losing shape. Brands like Funmit and SUNRRA emphasize their ABS frames and high-fiber filter paper, promising a lifespan of two to three years with proper care. The Poolzilla filters also feature a sturdy pleated design. Cheaper filters may have thin plastic that bends or tears after a few uses, so investing a little more in a reputable brand often pays off.

Ease of Maintenance and Cleaning
All the filters we reviewed are designed to be rinsed clean with a garden hose. However, the frequency of cleaning varies. Ultra-fine pleated filters may need rinsing every four to six weeks, while spring filters can go longer because they trap less fine debris. Some sets, like the LBLVBNEWD basket, include both a complete basket and individual panels, making replacement simple. The Zymurgoes tune-up kit goes a step further by including brushes, tracks, and climbing rings, so you can refresh multiple components at once. Easy installation without tools is a common feature across all products, which means you can swap filters in minutes. If you are considering a different robot altogether, the polaris freedom review covers a cordless alternative.
Final Thoughts
After evaluating all six options, our top recommendations cater to different needs. For pool owners who want the finest filtration at a budget-friendly price, the Poolzilla Pool Cleaner Ultra-Fine Filters deliver excellent clarity and a sturdy build for under fifteen dollars. If you prefer a complete refresh for your Nautilus CC Plus, the SUNRRA Ultra Fine Filters offer a reliable, durable set with a one-year warranty and proven compatibility. Both choices will keep your pool water sparkling and your robot performing at its peak throughout the swimming season.

Frequently Asked Questions
How often should I replace the filters in my Dolphin Nautilus CC?
With regular rinsing every four to six weeks, most high-quality replacement filters last two to three years. However, if you notice reduced water flow or visible tears in the fabric, it is time for a new set. Heavy pool usage or frequent storms may shorten lifespan.
Can I use Nautilus CC Plus filters on the original Nautilus CC?
No, the filter cartridges for the Nautilus CC Plus (part #9991432-R4) are not compatible with the original Nautilus CC. The original model uses a different filter basket design. Always check the product compatibility list before purchasing. The LBLVBNEWD basket we reviewed is one option for the original Nautilus CC.
What is the difference between fine and ultra-fine filters?
Fine filters capture larger debris like leaves and twigs, while ultra-fine pleated filters trap microscopic particles such as sand, dirt, and algae. For the clearest water, ultra-fine is preferred. Some tune-up kits, like the Zymurgoes, include both types for versatile cleaning.
How do I clean the Dolphin Nautilus CC filters properly?
Remove the filter panels from the robot and rinse them with a garden hose on a moderate setting. Avoid using a pressure washer or harsh chemicals, as they can damage the pleated fabric. Allow the filters to air dry completely before reinserting. For stubborn debris, gently brush the pleats with a soft brush. Regular cleaning every four to six weeks maintains optimal performance.
