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.
Buying Guide: What to Look for in a Reusable Robotic Pool Cleaner Filter
Compatibility with Your Cleaner
Before anything else, confirm that the filter fits your specific robotic pool cleaner model. Many reusable filters are model-specific, like the Ulticor Ultra Fine Filter Basket Compatible designed for Dolphin S50, S100, and others. Others, like the Pokin upgrade fine filter bag, fit only Aquabot wheeled models. Always double-check the manufacturer’s compatibility list to avoid returns.
Filtration Efficiency
Look for micron rating or material density. Ultra-fine baskets (like the Ulticor) use microfiltration technology to trap even tiny particles, while foam sponges (like the 6 Pack Filter Sponge for WYBOT A1) catch hair and sand. For the best balance, choose a dense foam or pleated cartridge that captures debris down to 2 microns or less.
Washability and Longevity
A reusable filter must withstand regular rinsing without losing shape or performance. Most sponge pads and fine mesh bags can be hosed off and air dried. The Yinage cartridge for Hayward cleaners, for example, is made from reinforced PET fiber that holds up through repeated cleanings. Replacements every 1 to 3 months keep suction strong.
Ease of Installation
No one wants a complicated swap. Sponge pads (like the csyls 5-pack) and foam inserts slide into the filter compartment without tools. Basket-style filters may require removing a plastic piece on older robots, check instructions. Simple installation saves time and encourages regular maintenance.
