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

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: What to Look for in Universal Robotic Pool Cleaner Parts
Choosing the right parts for your pool robot can feel overwhelming with so many options. Focus on these key criteria to ensure you get the most out of your purchase.
Compatibility with Your Cleaner Model
Not all parts fit every robot. Always check the manufacturer compatibility list before buying. For example, the Calvana (2 Pack) Replacement Gray Tracks work with many Maytronics Dolphin models, while the for CC Plus Tune Up Rebuild Kit with 9991433-R4 is specifically designed for the Dolphin Nautilus CC Plus. Universal parts, like retrieval hooks, often fit any brand, but always verify dimensions.

Material Quality and Durability
Pool environments are tough: sun, chlorine, and constant water submersion. Look for parts made from UV-resistant ABS plastic, stainless steel, or high-grade rubber. The KOPBTBOY Upgraded Stainless Steel Hook for Robotic boasts rustproof construction, while the M400 Ultra Fine Cartridge Filter Replacement from Funmit uses a heavy-duty ABS frame. Durable materials mean fewer replacements and lower costs over time.
Ease of Installation and Maintenance
Nobody wants to spend hours installing a simple part. Many of today’s components snap on without tools. The Dolphin Genuine Accessory caddy assembles in 15 minutes or less, and filter cartridges like those in the 9991414-R1 for Dolphin Pool Cleaner Cartridge require just a quick swap. For filter care, rinse every 4 to 6 weeks to extend life. Our article on best pool robot replacement chargers also highlights easy-to-install power solutions.
Specific Part Needed: Tracks, Filters, Brushes, or Storage
Identify what is wearing out. Worn tracks reduce climbing ability; replacement options like the Calvana (2 Pack) Replacement Gray Tracks restore grip. Clogged filters? The M400 Ultra Fine Cartridge Filter Replacement captures fine debris. Brush sets, such as those in the Pooloob PF1 Robotic Pool Cleaner Replacement Parts, boost scrubbing. And don’t overlook storage – the Dolphin Genuine Accessory caddy keeps everything organized. For more on specific components, see our best pool cleaner charging cable picks.
Retrieving your robot from the water is easier with hooks like the Dnairtly Pool Hooks for Poles or the Grevosea Pool Robot Retrieval Hook for All Robotic. Both are universal and attach to standard poles.
Final Thoughts
Investing in the right universal robotic pool cleaner parts keeps your pool spotless without the cost of a new machine. For a complete overhaul, the for CC Plus Tune Up Rebuild Kit with 9991433-R4 delivers everything you need for a Dolphin Nautilus CC Plus, from filters to brushes and tracks. If you only need to refresh your filtration, the M400 Ultra Fine Cartridge Filter Replacement from Funmit offers exceptional fine debris capture at a great value. Both options are reliable, easy to install, and built to last, giving you more time to enjoy your pool.
