- 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.
- Solid build quality with lightweight yet sturdy plastic construction.
Cons
- Not compatible with Dolphin Nautilus CC Pro or CC Supreme models, limiting its use for newer variants.

- As an aftermarket part, it may not perfectly match OEM quality or warranty coverage.
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. If you own one of the listed robots and want to keep your pool sparkling clean without breaking the bank, this filter is a smart buy.
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.

Buying Guide: Choosing the Right Dolphin Replacement Filter
Compatibility with Your Dolphin Model
Not all filters fit every Dolphin cleaner. Before buying, confirm your cleaner model and compare it with the filter’s compatibility list. Many aftermarket options, like the Ulticor Ultra Fine Filter Basket, support a wide range of Dolphin models including Active 10, S50, and Nautilus CC. Always double-check the product description to avoid mismatches.
Filtration Efficiency and Material
Look for filters that trap fine particles such as silt, sand, and algae. Ultra-fine options like the 9991467-r4 Filter Panels use pleated material to capture microscopic debris. For foam sponges, dense polyurethane offers excellent dirt retention. Higher efficiency means fewer passes and cleaner water.
Ease of Cleaning and Maintenance
Reusable filters save you money over time. Most filter baskets and panels can be rinsed with a garden hose. Some foam sponges are washable and air-dry quickly. Choose filters that are easy to remove and reinstall, so you spend less time on upkeep and more time enjoying your pool.

Build Quality and Durability
A well-constructed filter withstands repeated use and cleaning. Look for reinforced edges, sturdy plastic frames, and tear-resistant materials. Premium options like the FEATCH 2-Pack 3µm Filter Basket Insert feature silicone edging to resist wear. Investing in durable filters reduces the frequency of replacements.
Final Thoughts
Cyber Monday offers an excellent opportunity to upgrade your Dolphin pool cleaner’s filters at a great value. For maximum compatibility and ultra-fine filtration, we recommend the Ulticor Ultra Fine Filter Basket Compatible, which works with numerous Dolphin models and captures even the smallest debris. If you prefer a budget-friendly multi-pack for older Dolphin units, the 9991467-r4 Ultra-Fine Filter Panels deliver reliable performance and easy maintenance. Whichever you choose, your pool will thank you.
