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.

Pros
- Ultra-fine 10 micron filtration catches very small particles and improves water clarity
- Compatible with multiple wybot C2 models, including C2 Vision and C2 Pro
- Lightweight and compact design makes installation simple
- HEPA-grade media is rinseable for multiple cleaning cycles
- Affordable replacement option for robotic pool cleaner maintenance

The Ultra-fine Filter HEPA Filter replacement is designed for wybot robotic pool cleaners in the C2 family, including the C2, C2 Vision, C2 Pro, and C2 Pro Vision. It is a practical maintenance part for pool owners who want to keep their robot running efficiently without paying a premium for branded parts. If your current filter is clogged or losing suction, this replacement is a straightforward upgrade.
The HEPA-grade media captures particles down to 10 microns, which means fine sand, dust, pollen, and algae residue stay trapped in the filter instead of returning to the pool. That level of filtration is especially useful for pools with heavy use or for owners who notice cloudy water after cleaning. The ultra-fine construction helps maintain strong suction while keeping the water visibly clearer.
The filter is white, lightweight, and compact, weighing just 0.12 pounds. Its slim profile is designed to fit compatible wybot C2 models without adding bulk. The materials feel durable enough for repeated rinsing, though you should replace the filter once it becomes worn or misshapen.
Because this is a generic replacement part, you should verify the dimensions and fit against your original filter before ordering. It is also sold as a single filter, so households that clean frequently may want to keep a spare on hand. Customer feedback is limited at this time, so long-term durability is still being established.
Overall, this ultra-fine HEPA filter is a smart, budget-friendly replacement for wybot C2 series owners who want strong filtration and easy maintenance. It delivers the micron-level performance that helps keep pool water clean and supports the long-term operation of your robotic cleaner. If you need a dependable replacement filter for your compatible wybot model, this is a solid choice.

Buying Guide
Compatibility with Your WYBOT C1
Not every filter fits every WYBOT model. The C1 uses a specific foam sponge size and shape. Before buying, verify that the replacement matches your unit’s dimensions. Many filters listed here are designed for the A1 or C2 series, so double-check the product description. If you own a different WYBOT model, browse our replacement filters category for model-specific options.
Filtration Efficiency
The best filters capture fine particles like sand, hair, and leaves without clogging quickly. Look for dense foam or cotton construction with a pore size around 0.36 inches. Some premium options include HEPA layers that trap particles as small as 10 microns, ideal for allergy sufferers. A higher filtration rating means cleaner water and less strain on the pump.
Durability and Reusability
Washable filters save money and reduce waste. Choose sponges that hold their shape after repeated rinsing. Chlorine-resistant materials last longer in treated pool water. Most quality filters can be reused for several months before needing replacement. Avoid cheap options that disintegrate after a few washes.
Ease of Installation
Tool-free installation is standard for these filters. Simply open the filter compartment, slide out the old sponge, and insert the new one. Some packs include multiple pieces for quick swaps during heavy debris seasons. For more on accessories, visit our accessories page.
Final Thoughts
After reviewing the options, we recommend the 8‑Pk Foam Filter Replacement for its dense foam and excellent value, and the WYBOT C2 Replacemet Parts-Ultra Fine Filter if you need HEPA-grade filtration for the finest debris. Both options deliver reliable performance and easy maintenance, keeping your pool cleaner running like new all season long.

Frequently Asked Questions
How often should I replace the filter in my WYBOT C1?
Under normal use, replace the foam filter every 1 to 2 months. If you notice reduced suction or visible wear, swap it sooner. Washable filters can be rinsed weekly to extend their life.
Can I use a filter designed for the WYBOT A1 on my C1?
Not always. The C1 uses a different filter size than the A1. Always check the product dimensions and your owner’s manual. Some aftermarket filters list multiple compatible models, but verify before buying.
Are HEPA filters worth the extra cost for a pool cleaner?
If you have allergies or want the clearest water possible, yes. HEPA filters trap microscopic particles like pollen and fine sand. They are especially useful for pools near dusty areas or with heavy use. For more on filters, see our above ground pool cleaners guide.
How do I clean a reusable foam filter?
Rinse the sponge under tap water until the water runs clear. Squeeze out excess water and let it air dry completely before reinstalling. Avoid using soap or bleach, as residues can harm the pool chemistry.
