Clean Deeper
Filters function through a mechanical process called sieving. The Cayman's standard filter stops leaves and debris; the NanoFilter™ goes further, sieving fine algae, pollen and dust down to 2 microns.
Accessory
Upgrade your Dolphin Cayman's Gen-2 MaxBin with snap-in NanoFilter panels. Ultra-fine pleated filtration captures pollen, algae, bacteria, sand, and oil that standard filters miss.
Generation 2 filter technology cleans deeper than the standard filters before it. Add NanoFilter™ to your Cayman today. The deep ridges of the NanoFilter™ provide a 3X larger surface area, capturing the smallest particulate, including bacteria, algae, oil, leaves, and more.
The NanoFilter's woven and pleated fibers allow water to flow freely while effectively entrapping even the smallest particles. With its deep pleats and remarkable ability to capture debris, the NanoFilter outperforms all cartridges before it. With SnapLoc Filters, you can easily swap between the filter types in just seconds and customize each clean for the task at hand.

Unlike other filters, NanoFilters excel at removing oil. When oil is trapped, it forms a transparent sheath over the debris, which is easily removed during cleaning - improving turbidity and water transparency.
Want to switch filters? No problem. The quick-change SnapLoc panels let you change the media in seconds: NanoFilter™ for fine debris and algae, the standard filter for maximum suction after a storm.

When it comes to modern robotic pool cleaners, there are two main types of cartridge filters. The traditional filter found in many pool robots relies on a large-pored plastic mesh, which can be considered outdated. The NanoFilter's micro-pore spun-bonded polyester fabric creates a mesh that allows water to flow freely while trapping even the smallest particles. Its deep ridges and large surface area effectively capture debris, maintaining optimal water flow.
Prefer a second, ready-to-swap basket? The NanoFilter MaxBin™ for the Cayman comes with the panels already installed.
Yes. These NanoFilter™ panels are made for the Dolphin Cayman's Gen-2 MaxBin™ and snap into the existing basket in place of the standard panels.
No. The Cayman ships with standard SnapLoc filters that handle leaves and debris. NanoFilters are an optional upgrade for fine debris, algae, pollen, and oil.
Pop the panels off the side of the MaxBin, rinse them with a garden hose, and snap them back in. Never use a pressure washer or harsh chemicals.
Use the standard filter option for maximum suction when you need to pick up a bushel of leaves, then swap back to NanoFilter™ for everyday polishing.
