If you own a robotic pool cleaner, you already know that a clogged or worn filter basket can turn a chore into a headache.

In this guide, we’ve reviewed seven of the best replacement packs on the market, covering top brands like ULTICOR, TUOWS, FEATCH, Kerneed, Beatbot, and CLLOMAGY. Whether you have a Dolphin, Hayward, Aiper, or Beatbot robot, there’s a filter here for you. For more options, check out our roundup of the top robotic pool cleaner filter replacement kits.
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.

Maintenance is straightforward: after a cleaning cycle, simply remove the basket via the top access, pour out debris, and rinse with a hose. This design reduces downtime and keeps your cleaner running optimally.
A potential drawback is its limited compatibility with only AquaSense 2 and Aquasense cordless models, meaning it won't work with other pool cleaners. Additionally, while the fine mesh is excellent for small particles, it may require more frequent cleaning in heavily debris-filled pools.

Buying Guide: What to Look for in a 2-Pack Filter
Choosing the right replacement filter pack means matching your robot’s specifications and your pool’s debris load. Here are the key factors we evaluated in every product we reviewed.
Compatibility with Your Robot Model
Not all filters fit every robot. Always check the model list before buying. For example, the top robotic pool cleaner replacement filter packs we reviewed include many that are specifically designed for Dolphin, Hayward, Aiper, and Beatbot units. Some filters, like those from FEATCH, are tailored to a single brand, while others from ULTICOR cover a wide range of Dolphin models.
Filtration Micron Level
The finer the filter, the clearer your water. Standard filters capture large debris, while ultra-fine 3µm or 150µm meshes trap silt, sand, and even oils. If your pool collects fine dust or pollen, an ultra-fine option like the FEATCH 2-Pack for Aiper or the Ulticor Ultra Fine Basket is worth the upgrade. For a deeper dive, see our ultra fine filter guide.
Durability and Ease of Cleaning
Pool filters take a beating from chlorine, UV light, and constant water flow. Look for reinforced edges, ABS plastic frames, or silicone bonding. The best packs, like the Kerneed Spring Filter Cartridges, are built to last two to three years with proper rinsing every four to six weeks. For cordless robots, the fine filter 2-pack options offer a great balance of durability and easy snap-in replacement.
Value of a 2-Pack
A 2-pack gives you a spare, extending the time between purchases and ensuring you always have a clean filter ready. Products like the TUOWS 4-pack for Hayward Sharkvac and the Kerneed 4-pack for Dolphin offer even more bang for your buck. If you frequently clean a heavily used pool, a multi-pack is a smart investment. For more comparisons, visit our replacement filter basket hub.
Final Thoughts
After reviewing all seven contenders, we believe the best choice depends on your robot brand. For Dolphin owners, the Ulticor Ultra Fine Filter Basket Compatible stands out with its ultra-fine microfiltration and wide compatibility across dozens of models, making it a versatile upgrade. Meanwhile, Aiper Scuba S1 or V3 users will appreciate the FEATCH 2-Pack 3µm Filter Basket Insert, which delivers exceptional clarity and a tool-free swap. Whichever you choose, a fresh 2-pack will keep your robotic cleaner running efficiently all season long.

Frequently Asked Questions
How often should I replace robotic pool cleaner filters?
Most manufacturers recommend replacing filters every 6 to 12 months, depending on pool usage. If you clean your pool weekly, a 2-pack can last you a full season. For a deeper look, see our Aiper cordless vacuum guide for model-specific filter care.
Are 2-pack filters better than buying singles?
Yes, a 2-pack is almost always more cost-effective and lets you rotate filters so one is always clean. It minimizes downtime during heavy debris periods.
Can I use a different brand filter than my robot’s brand?
Absolutely, as long as the filter is listed as compatible with your specific model. Aftermarket brands like ULTICOR and TUOWS often offer equal or better filtration at a lower price.
How do I clean robotic pool cleaner filters?
Rinse with a garden hose after each use, and give them a deeper soak in a mild cleaning solution every four to six weeks. Avoid harsh chemicals or high-pressure washers that could damage the mesh.
