- 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.

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 is ideal for pool owners who want to maximize the cleaning efficiency of their robot and achieve crystal-clear water by trapping even the smallest particles.
The double-layer filtration system combines a standard mesh with an ultra-fine woven screen to capture leaves, hair, sand, and microscopic silt that ordinary baskets miss. This results in noticeably cleaner pool walls and waterline after each cycle, reducing the need for manual skimming and chemical dosing.
The basket features a snap-lock structure that clicks securely into the mounting groove of the Scuba S1, ensuring stable operation during cleaning. After use, the removable basket can be rinsed clean in seconds under a faucet, eliminating the need for brushes or tools. The lightweight plastic construction feels durable enough for regular use.
One limitation is that these baskets are only compatible with the Aiper Scuba S1 model, so owners of other robots cannot use them. Additionally, the ultra-fine mesh may clog faster in pools with heavy debris, requiring more frequent rinsing. As a relatively new product with no customer reviews yet, long-term reliability is not fully established.
Overall, the GOODYEELAB Ultra-Fine Filter Basket Screen offers a significant upgrade in filtration for Aiper Scuba S1 owners. The 2-pack provides excellent value, and the easy rinse design simplifies maintenance. If you own this pool cleaner and want better water clarity with less effort, this replacement set is a smart investment.
Pros
- Exceptional filtration captures even the smallest impurities.
- Washable and reusable, saving money over time.
- Easy installation without tools or extra parts.
- Designed to protect the pool cleaner's motor from debris damage.
- Compatible with two popular Aiper models.
Cons

The Fishing Port Washable Replacement Ultra-Fine Filter Bag is a dedicated accessory for the Aiper Scuba S1 and Scuba S1 2025 robotic pool cleaners. It is designed for pool owners who want to maintain peak water clarity without frequently buying disposable filters. This cloth-only replacement fits into the existing frame of your cleaner, offering an eco-friendly and cost-effective solution.
The standout feature is its ultra-fine nonwoven fabric, which traps even microscopic particles like fine sand, algae spores, and tiny leaf fragments. This level of filtration not only keeps your pool water crystal clear but also prevents debris from reaching and damaging the cleaner's motor. The material is engineered to balance high filtration accuracy with optimized water flow, so your robot doesn't lose suction or efficiency.
Installation is refreshingly simple: just remove the old filter and snap the new cloth into the frame. No tools are needed, and the whole process takes under a minute. Maintenance is equally straightforward, with the manufacturer recommending a rinse every 4 to 6 weeks. The washable design means you can reuse this bag multiple times, reducing waste and long-term costs.
A notable drawback is that only the filter cloth is provided, not the frame. You must reuse the frame from your original Aiper filter. This could be an issue if your frame is damaged or missing. Additionally, as a third-party brand, Fishing Port lacks the established reputation of Aiper's own accessories, and there are no user reviews yet to confirm durability over time.
Overall, the Fishing Port replacement filter bag offers strong value for Aiper Scuba S1 owners who prioritize fine filtration and easy maintenance. If you already have a functional frame and want a washable alternative to OEM filters, this product is worth considering. Just be aware that it is unproven in the long term, and you'll need to keep your existing frame in good condition.
Buying Guide
Filtration Efficiency
The primary purpose of an algae filter basket is to trap the tiniest particles, including algae cells, fine sand, and dust. Look for baskets that specify “ultra-fine” or “microfiltration” technology. These use dense fabric or multiple layers to capture particles as small as a few microns. The Ulticor Ultra Fine Filter Basket Compatible and Ultra-Fine Filter Basket Part 9991460-r1 both emphasize high-quality materials for superior filtration. For Beatbot models, the (2025 NEW) Beatbot Genuine Filter Basket features a 150μm mesh that catches oils and lotions along with debris.
Compatibility
Not all filter baskets fit every robot. Ensure compatibility with your specific model. Dolphin users should check if their unit requires the 9991460-R1 or 9991458-R1 part number. The Gearwiz Ultra Fine Filter Basket Compatible works with newer Dolphin models like Active 20 and M600. For Aiper Scuba S1 owners, the fishing port Ultra Fine Filter Basket Compatible offers a snap-in replacement. Always double-check the product description for model lists to avoid purchasing the wrong item. Visit our Replacement Filters category for more options.
Durability and Maintenance
A quality filter basket should withstand repeated cleaning and last several seasons. Most products use reinforced ABS plastic frames and washable fabric. The 2 Set Ultra Fine Filtration Basket for Dolphin includes both a complete basket and replacement panels, extending its lifespan. Regular rinsing every 4-6 weeks keeps performance optimal. Avoid baskets with flimsy frames that warp under water pressure. The Ultra-Fine Filter Basket Screen (2pcs) for Aiper Scuba S1 features a double-layer structure for added durability.
Ease of Installation
Look for tool-free designs that snap into place. Many models, like the fishing port Ultra Fine Filter Basket Compatible, require no special tools. The 2 Set Ultra Fine Filter Basket for Dolphin includes replacement panels that slide in easily. Some units may require removing a plastic piece for older models; videos are often available for guidance. For a smooth experience, choose baskets with clear instructions or online tutorials.

Can I use an ultra-fine filter basket with any Dolphin robot?
Not all models are compatible. Check the product description for a list of supported models. For example, the 9991460-R1 basket works with S50, S100, Active 10, and many others, but not with Nautilus CC Pro or CC Supreme. Always verify before purchasing.

No, these baskets are designed as direct replacements and pose no risk. They use sturdy frames that fit securely. However, avoid overloading the basket with large debris; empty it after each use to maintain proper water flow.
What is the difference between a standard and ultra-fine filter basket for algae?
