Pros
- High-efficiency microfiltration captures fine dirt, sand, and leaves for pristine pool water.
- 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.
- Older versions of Active 10 or S50 may require removal of a plastic piece for proper fit, which could be inconvenient for some users.
- 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.

Standout features include a powerful 150μm mesh that traps everything from leaves and stones to tiny particles like sand, hair, oils, and lotions. The built-in Hall sensor automatically detects the basket upon installation, streamlining the user experience and enhancing overall efficiency.

- 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.

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 Pool Robot Filter Basket for Sand
Filtration Micron Rating
The micron rating determines the smallest particle the filter can catch. For sand, you want a basket rated at 150 microns or finer. Many options here use ultra-fine microfiber or nonwoven fabric that traps sand, silt, and even algae. A lower micron number means finer filtration, but it may require more frequent cleaning. Look for baskets that balance fine capture with good water flow.
Compatibility With Your Robot Model
Not all filter baskets fit every robot. Check the model list carefully. The Ulticor and REEPLAR baskets, for example, work with many Dolphin models like the Active 10, S50, and Nautilus CC, but not with the Nautilus CC Pro or Supreme. The Gearwiz basket fits larger Dolphin units like the Active 20 and M600. If you have an Aiper Scuba S1, consider the fishing port baskets. Always verify your robot’s part number before buying.
Build Quality and Durability
A sturdy frame prevents cracking under water pressure and during cleaning. Look for ABS plastic frames and reinforced seams. The Beatbot genuine basket uses high-quality polyester with a Hall sensor for automatic recognition. Many aftermarket baskets promise 2 to 3 years of life. Rinsing every 4 to 6 weeks extends their lifespan. For more on maintaining your robot, see our top wall climbing brush picks.
Ease of Cleaning and Maintenance
Sand can clog a filter quickly. You want a basket that pops out easily and rinses clean. Most models here offer tool-free removal. The 2-set LBLVBNEWD includes extra replacement panels, so you can swap and clean later. The fishing port baskets for Aiper are simple to snap in. Regular cleaning keeps your robot running efficiently and your pool sand-free.
Final Thoughts
Choosing the best pool robot filter basket for sand comes down to your robot model and your budget. For Dolphin owners who want top-tier microfiltration, the Ulticor Ultra Fine Filter Basket Compatible earns our highest rating with its ultra-fine capture and broad compatibility. If you need a basket for a larger Dolphin like the Active 20 or M600, the Gearwiz Ultra Fine Filter Basket Compatible offers excellent value and proven performance. Both options will keep sand and fine debris out of your pool, letting you enjoy crystal-clear water all season long.

Frequently Asked Questions
How often should I clean my pool robot filter basket for sand?
For best performance, rinse the filter every 4 to 6 weeks. If you have heavy sand or debris, you may need to clean it more frequently. Regular cleaning prevents clogs and maintains suction power. For more tips, check our guide on traction brushes that help your robot climb walls.
Can I use a filter basket from one brand with a different robot?
Only if the basket is explicitly listed as compatible. Many aftermarket baskets fit multiple Dolphin models, but always verify the part number. Using an incompatible basket may cause poor fit or damage. Stick to baskets designed for your specific robot model.
What micron rating is best for trapping sand?
A rating of 150 microns or finer is ideal for sand. The Beatbot genuine basket uses a 150μm mesh, while most ultra-fine baskets in this guide capture particles down to that range. Finer micron ratings (e.g., 100μm) will catch smaller silt but may require more frequent cleaning.
How long do these filter baskets last?
With proper care, most ultra-fine filter baskets last 2 to 3 years. The LBLVBNEWD set includes replacement panels to extend life. Rinse after each use and store in a dry place to maximize durability.
