Detailed Review

The SUNRRA Ultra-Fine Filter Basket is a replacement part designed specifically for a wide range of Dolphin and compatible robotic pool cleaners. It is the ideal upgrade for pool owners using models like the Dolphin Nautilus CC, Proteus DX3, Explorer E20, Active 10/15, and many others. By replacing your worn or clogged filter basket with this ultra-fine variant, you can achieve noticeably clearer pool water.

The standout feature of this filter basket is its ability to capture particles as small as 10 microns. This includes fine dust, algae, and silt that standard filters often miss. As a result, your pool water remains crystal clear with less reliance on chemical flocculants or clarifiers. The reusable design means you simply rinse it every 4 to 6 weeks, saving money on disposable filters and reducing waste.

Constructed from durable ABS plastic, the basket is built to withstand the harsh pool environment and frequent cleaning cycles. SUNRRA claims a lifespan of 2 to 3 years with proper maintenance. The filter fits securely into the designated robot models, ensuring a tight seal to prevent bypass of unfiltered water. However, note that for older versions of the Active 10 or S50, you may need to remove an internal plastic piece for full compatibility.

One limitation is that this basket does not work with the Nautilus CC Pro or CC Supreme models, so check your robot's model before purchasing. Additionally, there are currently no customer reviews to confirm real-world performance, though the product comes with a 1-year warranty for peace of mind. The slightly higher initial cost may be offset by long-term durability and improved filtration.

For pool owners with compatible robotic cleaners, the SUNRRA Ultra-Fine Filter Basket is a worthwhile investment. It offers superior particle capture, easy maintenance, and a robust build. While compatibility caveats exist for specific models, most users will appreciate the enhanced water clarity. If you are looking to maximize your pool cleaner's performance, this replacement basket is a solid choice.

Buying Guide: What to Look for in a Dolphin Nautilus CC Plus Filter Basket

Compatibility with Your Dolphin Model

Not all filter baskets fit every Dolphin pool cleaner. The Nautilus CC Plus shares the same basket design as the standard Nautilus CC, S50, S100, Active 10, and many others. Most aftermarket baskets list part numbers 9991460-R1 and 9991459-R1. Always verify that the basket is compatible with your specific model before purchasing. Some baskets explicitly exclude Nautilus CC Pro and Nautilus CC Supreme, so double-check.

For a full compatibility list, see our Dolphin Nautilus CC filter basket replacement guide.

Filtration Efficiency: Ultra-Fine vs. Standard

Ultra-fine filter baskets capture particles down to 10 microns, including fine dirt, pollen, and dust that standard baskets miss. If your pool often has cloudy water or fine sediment, an ultra-fine basket is a worthwhile upgrade. Many aftermarket options use advanced microfiltration technology that traps large debris while letting fine particles pass through to prevent clogging.

Durability and Build Quality

Filter baskets are made from ABS plastic or similar materials. Premium baskets feature a sturdy frame that resists cracking under pressure. Look for reinforced edges and a spring-loaded bottom that collects leaves and large debris. A well-built basket can last two to three years with proper care. Genuine Dolphin parts often cost more but offer certified quality.

Ease of Cleaning and Maintenance

All filter baskets are reusable and should be rinsed every four to six weeks. Some designs have a smooth surface that makes debris slide off easily. A basket with a bottom spring filter simplifies removing large objects. Choose a basket that is easy to lift out and clean without tools.
