Pros
- Precise fit ensures optimal filtration
- Washable and reusable for cost savings
- Easy tool-free installation
- Dense foam captures fine particles
- Standard 8-pack supply reduces hassle of frequent ordering
Cons

The Gosipea 8-Pack Foam Filter Replacement is designed specifically for the WYBOT A1 cordless robotic pool cleaner. 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. Users will appreciate that the filters are washable and reusable, quickly rinsing under tap water and air-drying without losing shape. This durability translates to lower long-term costs and less waste.
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. Additionally, while washable, the foam may eventually wear out after many cycles, especially with heavy debris loads. Checking the official size guide before purchase is recommended.
Overall, the Gosipea 8-pack offers excellent value for WYBOT A1 owners seeking reliable, washable filter replacements. With easy installation, effective filtration, and a generous supply, it extends the cleaner's lifespan and performance. A smart choice for maintaining a clean pool with minimal effort.

- Works with a wide range of popular Dolphin robot models, reducing the need for multiple filter types.
- Easy to clean and maintain with no special tools required.
- Affordable price compared to manufacturer replacement filters.

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.

- Wide compatibility saves hassle of finding exact match for various Dolphin models
- Simple maintenance with periodic rinsing; no tools required
- Cost-effective alternative to OEM parts with comparable performance

The Fiitzn Ultra Fine Filtration Basket is a replacement filter designed for a wide range of Dolphin robotic pool cleaners, including models like the S50, Active 15, Echo, Nautilus CC, Encore, E10, E20, Proteus DX3, Solo, and Advantage. This part (9991460-R1) is ideal for pool owners seeking an affordable, high-performance alternative to the original filter. It is especially suited for those who want to improve water clarity by trapping fine particles without sacrificing cleaning efficiency.
The standout feature of this basket is its microfiltration technology, which captures small debris while allowing larger particles to pass through. This design prevents the filter from clogging quickly, ensuring consistent suction and longer cleaning cycles. In real-world use, this means less downtime for rinsing and more effective pool maintenance, even in dirty conditions. The basket maintains strong performance over weeks of use before needing a quick rinse.
Build quality is solid thanks to the ABS plastic frame, which resists cracking and deformation under pressure. The filter layer is securely supported, reducing the risk of tearing during operation. Installation is straightforward: it fits exactly like the original part, so no modifications or adapters are needed. Rinsing every 4-6 weeks keeps it working optimally, and with proper care, the basket can last 2-3 years, offering excellent value.
One potential drawback is that in extremely dirty pools, the filter may need more frequent rinsing to maintain flow. Additionally, the package includes only one basket, so owners of larger pools might need to buy a second. Also, while compatibility is broad, it does not cover every Dolphin model, so double-checking the list is wise. These are minor trade-offs for the price and performance.
Overall, the Fiitzn Ultra Fine Filtration Basket delivers on its promise of efficient fine debris capture and durability. It is a smart upgrade or replacement for Dolphin pool cleaner owners who want to keep their water crystal clear without breaking the bank. The combination of microfiltration, sturdy construction, and broad compatibility makes it a reliable choice for routine pool care.

Buying Guide
When selecting a replacement filter for your WYBOT C1, you need to consider more than just the price. The right filter ensures your pool cleaner operates efficiently, captures the right debris, and lasts through many cleaning cycles. Here are the key factors to evaluate before making a purchase.
Compatibility with Your WYBOT C1 Model
Not all filters are universal. The WYBOT C1 and the C1 OS800 have specific filter compartments, and using the wrong size can lead to poor sealing or improper fit. Always verify the model number and check the official size guide before ordering.
For instance, the 8-Pk Foam Filter Replacement is designed for the WYBOT A1, but it also fits the C1 if the dimensions match. The Filter Basket With Lid is explicitly made for the C1 OS800, ensuring a precise fit. When in doubt, measure your current filter or consult the product description.
Filtration Efficiency and Debris Capture
The primary job of a filter is to trap dirt, hair, and small particles. Dense foam filters like the 8-Pk set offer excellent fine-particle capture while maintaining water flow. On the other hand, a basket with a tight lid prevents larger debris from escaping back into the pool.
Consider what your pool deals with most: fine silt, leaves, or larger twigs. For fine particles, a foam filter is ideal. For bulk debris, a basket with a secure lid is more effective. Understanding your pool’s needs helps you choose the right filtration method.
Ease of Maintenance and Durability
Replacement filters should be easy to clean and long-lasting. Foam filters can be rinsed under tap water and air-dried, making them reusable multiple times. A basket with a lid should open easily for quick emptying and be made from sturdy materials that withstand frequent use.
Look for products that promise no-tool installation and simple cleaning. Both the foam filters and the basket we reviewed emphasize tool-free installation and straightforward maintenance, saving you time and effort. For more tips on maintaining your pool robot, see our WYBOT A1 filter replacement guide.
Final Thoughts
Choosing the right filter for your WYBOT C1 comes down to your specific cleaning needs. If you prioritize fine particle capture and want a budget-friendly, reusable option, the 8-Pk Foam Filter Replacement is an excellent choice. For those dealing with larger debris and seeking a durable, sealed basket, the Filter Basket With Lid offers reliable performance and easy emptying. Both options are verified to fit their respective models and ensure your pool stays pristine with minimal effort.
