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.

- 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

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
Filtration Type: Fine vs. Ultra-Fine
Fine filter panels use a screen-like mesh designed to trap larger debris such as leaves, twigs, and insects. They are ideal for initial seasonal cleanings when your pool has heavy debris. Ultra-fine filters, often pleated, capture smaller particles like sand, dirt, and algae spores, keeping the water crystal clear for everyday use. Consider your pool’s typical debris load when choosing.
For example, the PUREBURG Fine Filter Panels Compatible are excellent for spring startup, while the Ultra-Fine Filter Panels 9991466-R4 Compatible from PROOVEELLY are better for ongoing fine filtration.
Compatibility with Your Dolphin Model
Not all filters fit every Dolphin robot. Always verify that the replacement panels match your specific model number. Many filters are designed for the Nautilus CC Plus, M200, M400, and M500, but may not work with older Nautilus CC or Triton models. Check the product description for a list of compatible models before ordering.

Build Quality and Longevity
Durable frames made from ABS plastic resist cracking and warping under water pressure. Pleated filter media with strong support layers maintain shape and filtration efficiency over time. High-quality filters can last two to three years with regular rinsing every four to six weeks. Brands like PUREBURG and Funmit use heavy-duty materials that hold up well.
Value: Pack Size and Cost per Panel
Filters are sold in packs of four or eight panels. While a larger pack has a higher upfront cost, the per-panel price is often lower, saving you money over time. Consider how often you need replacements. If you clean your pool weekly, an eight-pack may be more economical. For occasional use, a four-pack may suffice.
