- 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.

This filter basket is ideal for pool owners who want to maintain peak filtration performance in their Beatbot cleaner without resorting to third-party parts.

Buying Guide
Filtration Efficiency
The primary job of a filter basket is to trap debris, from large leaves to microscopic particles like sand and algae. Look for baskets labeled as ultra-fine or featuring micron ratings. For example, the Beatbot genuine filters use a 150µm mesh, capturing even tiny impurities. The Ulticor Ultra Fine Filter Basket uses microfiltration technology to keep your pool the cleanest. A higher filtration efficiency means less work for your pool’s main pump and clearer water.
Compatibility with Your Robot Model
Not all filter baskets fit every robot. Many aftermarket options are designed for popular models like Dolphin (S50, S100, Active 10, Nautilus CC), Aiper Scuba S1, or Beatbot AquaSense series. Before buying, verify your robot’s model number. For instance, the REEPLAR basket is compatible with many Dolphin models but explicitly not with Nautilus CC Pro or Supreme. The Poolzilla basket lists specific Dolphin models and warns about incompatibility with older Nautilus versions. Always check the product description to avoid returns.
Ease of Cleaning and Durability
A washable filter basket should be simple to remove and rinse. Most baskets in our list are designed for quick snap-in replacement and tool-free cleaning. For example, the IdealThingShop filters for Aiper Scuba S1 feature an open-basket design that rinses clean under tap water. Durability matters too; look for reinforced seams, sturdy plastic frames, and high-quality materials that withstand repeated use. The fishing port basket for Aiper Scuba S1 boasts reinforced seams and a sturdy frame that retains its shape.
