- 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. 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

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: How to Choose the Right Replacement Filter
Compatibility with Your Pool Cleaner Model
The first step is verifying that the filter fits your specific robot. Many aftermarket filters, like the Ulticor Ultra Fine Filter Basket Compatible, work with a wide range of Dolphin models, but some are model-specific. For AIPER owners, the FEATCH 2-Pack 3µm Filter Basket Insert for Aiper is designed exclusively for the Scuba S1. Always double-check the model number before buying.
If you have a Hayward or Polaris robot, options like the TUOWS 4-pack or FFyan fine filter canister are excellent matches. For more advice on compatible accessories, visit our AIPER category page for model-specific recommendations.
Filtration Efficiency and Micron Rating
Filters capture debris at different levels. Ultra-fine filters, like the 3 µm FEATCH insert, trap microscopic particles such as silt and sand, leaving waterline and walls spotless. In contrast, foam sponges (e.g., the 8‑Pk for WYBOT A1) handle leaves and hair but may let finer particles through. For general maintenance, a dense foam works well; for crystal-clear water, opt for a pleated or mesh design with a lower micron rating.
The Ulticor basket uses microfiltration technology, while the Dreame original basket captures twigs and gravel. Choose based on your pool’s typical debris load. If you often deal with fine dirt, consider a double-layer system.
Build Quality and Ease of Cleaning
A durable filter saves money over time. Look for reinforced edges, heavy-duty ABS plastic, or silicone edging that resists tearing. Many filters are washable and reusable, simply rinse under a garden hose. The 8‑Pk Foam Filter Replacement from Gosipea and the csyls 5-pack both withstand repeated washing. For long-term value, a multi-pack is ideal, especially during Black Friday sales.
Installation should be tool-free. Products like the Pooloob foam sponges and the Cordless Pool Cleaner sponges snap in without hassle. For more tips on maintaining your cleaner, read our best pool robot traction brush.

Frequently Asked Questions
How often should I replace my robotic pool cleaner filter?
It depends on usage and debris load. Most manufacturers recommend cleaning the filter after every 2 to 4 uses and replacing it every 1 to 2 months during peak season. In 2026, many Black Friday deals offer multi-packs that keep you stocked for a full year.
Are aftermarket filters as good as OEM ones?
Yes, many aftermarket filters from brands like ULTICOR, FEATCH, and Gosipea use high-quality materials that match or exceed OEM specs. They often cost less and are washable. Just ensure compatibility with your specific model before purchasing.
Can I use a foam filter instead of a mesh basket?
Yes, foam filters are excellent for capturing hair, leaves, and larger debris, but they may not trap fine silt. If your pool has fine sand or algae, an ultra-fine mesh basket like the AIPER Scuba S1 3 µm insert is better. For general use, a combination works well.
What is the best way to clean reusable filters?
Rinse the filter with a garden hose using moderate water pressure. For foam sponges, squeeze out debris gently, avoid twisting. Let them air dry completely before reuse. Avoid harsh chemicals that could degrade the material. For more maintenance tips, visit our above-ground pool cleaners guide.
