In this guide, we review eight washable filters from brands like fishing port, Tanxier, and haoranli. Whether you need a sponge, cotton, or mesh design, we have you covered.

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
- Filter cloth only, no frame included; requires reusing the original frame from your cleaner.
- Brand may be less established than OEM options, which could affect long-term durability confidence.
- No customer reviews yet, so real-world performance is unverified.
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: What to Look For in a Washable Pool Robot Filter
Filter Material: Sponge, Cotton, or Mesh?
The material determines how well the filter traps particles and how easy it is to clean. Sponge filters (like those from GOODYEELAB) are soft and capture hair and leaves. Cotton sponges (GAUUPAUC) are denser and catch finer silt. Mesh or fabric filters (fishing port) excel at trapping ultra-fine sand and algae. Choose based on the debris you encounter most often.
For heavy leaf pickup, a sponge or cotton blend works well. For fine dirt, a mesh basket is ideal. Many users prefer cotton for its balance. See our best robotic pool cleaner replacement filter for leaves for more details.
Compatibility with Your Robot Model
Not all filters fit all robots. The products reviewed here are designed for specific models: WINNY HJ1102P, Ai per Scuba S1, PoolMr, Ray, and WYBOT A1. Always verify compatibility before purchase. For example, the Csxydz sponges fit only Ray and PoolMr units, while Tanxier filters are universal for many robots. Check your cleaner’s manual.
If you have an Ai per Scuba S1, both fishing port and the Cotton Sponge options work. For WINNY owners, the GOODYEELAB replacement set is a perfect match. Visit our replacement filters category for more model-specific guides.
Ease of Cleaning and Maintenance
Washable filters save time, but some are easier to rinse than others. Cotton sponges (like GAUUPAUC) require a simple squeeze under a faucet. Mesh fabric baskets (fishing port) need a gentle spray to remove trapped particles. All reviewed filters are reusable, but longevity varies. The GOODYEELAB sponges hold their shape well after many washes.
For optimal performance, rinse after each use and replace every few months. The Tanxier cartridge features an easy-rinse design that integrates seamlessly. For more tips, read our best ultra fine pool cleaner filter for dirt review.
Filtration Efficiency
The filter’s ability to capture tiny particles directly affects water clarity. Ultra-fine mesh (fishing port) and dense cotton (Csxydz) are best for clear water. Sponge filters catch larger debris but may let fine dust through. If you have a lot of fine sand or algae, choose a filter with a high density rating.
The Tanxier mesh panel is particularly effective at filtering out fine particles. Pair it with a best pool robot replacement filter for daily cleaning routine to maintain clarity.
Final Thoughts
After reviewing eight washable pool robot replacement filters, our top recommendations cater to different needs. For those who want a versatile, easy-to-clean option that works with PoolMr and Ray robots, the Washable Cotton Cleaner Filter Sponge For PoolMr offers exceptional value with its durable cotton construction and four-pack supply. If you own an Ai per Scuba S1 and prioritize ultra-fine filtration, the fishing port Ultra Fine Filter Basket Compatible captures even microscopic debris and maintains its shape through many washes. Both filters are washable, reusable, and will keep your pool crystal clear all season long.
