- 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.

The Aiper Scuba S1 is a 2026 upgrade to Aiper's popular robotic pool cleaner line. Designed for pool owners who want hands-free maintenance, it tackles floors, walls, waterline, and shallow areas. With a 270-minute runtime in Eco Mode, it suits both daily upkeep and deep cleaning sessions.
The Scuba S1 uses 11 high-precision sensors and dual-path algorithms for smart navigation. Its WavePath cleaning pattern minimizes overlap while adapting to your pool's layout in real time. The dual filtration system combines a 3-micron ultra-fine filter with a 180-micron standard filter to capture everything from fine dust to leaves.
Caterpillar Treads provide strong climbing ability and mobility, allowing the cleaner to transition smoothly from floor to walls. The unit weighs 17 pounds and measures 15.3 x 8.7 x 17.5 inches, making it sturdy but manageable. App support adds convenience with Eco Mode, scheduled cleaning, and a weekly custom plan.
The cleaner requires app connectivity to access Eco Mode and advanced scheduling, which may not appeal to users who prefer simple controls. Shallow area cleaning is limited to areas above 12 inches, so very shallow shelves may be missed. At 17 pounds, lifting it out of the pool for filter cleaning takes some effort.
Overall, the Aiper Scuba S1 offers comprehensive coverage, long runtime, and excellent filtration in one package. It is a strong choice for pool owners who want a reliable, app-enabled cleaner with minimal overlap and maximum convenience. The 2-year warranty adds peace of mind for long-term use.

The Dolphin Nautilus CC is a robotic pool cleaner designed to take the hassle out of pool maintenance. It is best suited for owners of above-ground or in-ground pools up to 33 feet in length who want a set-it-and-forget-it solution. With its wall-climbing ability and active scrubbing brush, this unit promises a thorough clean without manual effort.
Standout features include the top-load filter basket, which makes emptying debris quick and mess-free. The plug-and-play system means you can start cleaning in minutes: just plug it in, drop it in the water, and let it run for about two hours. Real-world performance is strong on walls and floors, though heavy debris may require more frequent filter cleaning.
Design-wise, the Nautilus CC is compact and lightweight at under 15 pounds, making it easy to lift in and out of the pool. The blue/black color scheme is standard, and the build quality feels durable. Dolphin has a legacy of reliability, and this model continues that tradition with robust materials and a simple interface.
One potential drawback is that the filter basket, while convenient, can fill up quickly in pools with lots of leaves or sand, requiring attention mid-cycle. Also, the price is higher than entry-level cleaners, but the added wall scrubbing and filter ease justify the cost for many users.
Overall, the Dolphin Nautilus CC is an excellent choice for pool owners who value convenience and effective cleaning. It delivers on its promises with minimal fuss, making it a worthwhile investment for maintaining a sparkling pool. If your pool fits within the size limit and you want to reduce manual work, this cleaner is highly recommended.
