The Ulticor Ultra Fine Filter Basket is an aftermarket replacement designed specifically for a wide array of Dolphin robotic pool cleaners. It is an ideal choice for pool owners who already own compatible models such as the Dolphin S50, S100, Active 10/15, Echo, T15, T25, Proteus DX3, Saturn, Cayman, Escape, and others. This basket is not intended for the Nautilus CC Pro or Supreme versions, so buyers should verify compatibility before purchasing.
What sets this filter apart is its microfiltration technology, which captures even the tiniest debris particles. In real-world use, this translates to a noticeably cleaner pool with clearer water, as fine dirt, sand, and pollen are effectively trapped. The basket is easy to rinse and clean every four to six weeks, maintaining peak performance without hassle. Users report that it fits snugly and works reliably cycle after cycle.
The design is straightforward: a white, lightweight plastic basket measuring roughly 9x5x7 inches. Build quality feels solid for an aftermarket part, though it may not have the exact finish of an OEM component. The inclusion of installation tips for older Active 10 or S50 units (which may need a small internal plastic piece removed) shows attention to compatibility details. A video guide is available upon request to assist with that adjustment.
Potential drawbacks are mostly centered on fitment limitations. Owners of Nautilus CC Pro or Supreme will need to look elsewhere. Also, the need to modify older robots could be a minor inconvenience for those not comfortable with simple DIY tasks. However, for the vast majority of compatible users, installation is plug-and-play.
Overall, the Ulticor Ultra Fine Filter Basket offers excellent value for money. It delivers superior filtration at a lower price than official replacements, while covering a wide range of popular Dolphin models.

It comes as a set of eight polyurethane foam sponges that maintain your cleaner's filtration efficiency over time. This product is ideal for pool owners who want to keep their robotic cleaner performing at its best without frequent replacements.
The dense foam structure captures fine dirt, hair, and small debris, ensuring consistent suction power during cleaning cycles.

Each sponge is crafted to original standard dimensions for a precise fit into the WYBOT A1's filter compartment. The tool-free installation allows for quick swaps after swimming or routine maintenance, saving time and effort. The white color is neutral and does not affect pool chemistry.
One potential drawback is that these filters are only compatible with the WYBOT A1 model, so owners of other cleaners must verify dimensions.

These pleated cartridge filters are ideal for pool owners who want to maintain sparkling water without frequent skimming. They fit a wide range of models including the S200, Active 20, Proteus DX4, M600, and many more, making them a versatile upgrade for most Dolphin owners.

Compatibility is extensive, covering over 25 Dolphin and Maytronics models, which adds significant value for households with multiple cleaners or future upgrades.
One potential drawback is that the ultra-fine mesh may clog faster than coarser filters, especially in heavily debris-laden pools.

Buying Guide
Compatibility with Your Pool Cleaner
The most important factor when choosing a replacement filter is ensuring it fits your specific robotic pool cleaner model. Many filters are designed for popular brands like Dolphin, Hayward, and WYBOT, but compatibility varies widely. Always double-check your cleaner’s model number and compare it with the filter’s list of compatible devices. For example, the Ulticor Ultra Fine Filter Basket Compatible works with numerous Dolphin models, while the 4 Pack for Hayward Sharkvac Filters RCX70101PAK2 is tailored to TigerShark and SharkVac series. Using the wrong filter can reduce suction or let debris slip through, so take a moment to verify compatibility before purchasing.
Filtration Efficiency and Material
Filtration quality determines how clean your pool water stays. Ultra-fine filters, like those with microfiltration technology or 180-micron mesh, capture tiny particles such as sand, silt, and algae spores that standard filters miss. Pleated cartridges and dense foam sponges each have their strengths: pleated filters offer high surface area for trapping debris, while foam sponges are great for catching hair and fine dirt. The Replace Part#9991467-R4 Ultra-Fine Filter Panels use a pleated design for excellent dirt capture, and the 8‑Pk Foam Filter Replacement provides dense foam that catches fine particles effectively. Consider your pool’s typical debris load when choosing between these materials.
Ease of Cleaning and Maintenance
Replacement filters should be simple to clean and reuse, saving you time and money. Most filters can be rinsed with a garden hose and air-dried, but some require more frequent attention. Look for filters with sturdy frames and reinforced mesh that resist tearing during cleaning. The Y20 Robotic Pool Cleaner Replacement Filter features a quick-release structure for effortless rinsing, while the csyls 5 pcs Filter sponges for WYBOT A1 Robotic are washable and reusable, with a recommended replacement every one to two months. Regular maintenance extends filter life and keeps your pool cleaner running at peak performance.

Value and Pack Size
Cyber Monday deals often come in multi-packs, offering great value for regular filter changes. Buying a pack of four, eight, or twelve filters reduces the per-unit cost and ensures you always have a spare on hand. The Pool Cleaner Sponge Replacement Pads for WINNY come in a set of twelve, providing long-term value for frequent users. Similarly, the 4 Pack for Hayward Sharkvac Filters RCX70101PAK2 is an economical choice for Hayward owners. Consider how often you clean your pool and how quickly you go through filters to determine the best pack size for your needs.

Frequently Asked Questions
How often should I replace my robotic pool cleaner filter?
It depends on usage and pool conditions. For most filters, rinsing after each use and replacing every one to three months is recommended. Ultra-fine filters may last longer if cleaned regularly. Check the manufacturer’s guidelines for your specific model.
Can I use a different brand filter for my Dolphin pool cleaner?
Yes, many aftermarket filters are compatible with Dolphin models, but you must verify the model number and dimensions. Brands like ULTICOR and Fiitzn offer direct replacements for popular Dolphin cleaners. Always confirm compatibility before purchasing to avoid fitment issues.
Are foam filter sponges as effective as pleated cartridges?
Both have strengths. Foam sponges excel at trapping fine particles like hair and dirt, while pleated cartridges offer a larger surface area for capturing larger debris. Choose based on your pool’s typical debris and your cleaning preferences. For example, the 8‑Pk Foam Filter Replacement is great for fine filtration, while pleated panels like the 9991467-r4 Ultra-Fine Filter Panels for Dolphin handle larger loads.
What does a 180-micron filter do that a standard filter doesn’t?
A 180-micron filter captures very fine particles like sand, silt, and microscopic debris that standard filters might miss. This results in clearer water and reduces the workload on your main pool pump and filter system. The Y20 Robotic Pool Cleaner Replacement Filter features this ultra-fine mesh for superior clarity.
