Next Generation Technology

There are two types of cartridge filters available on modern robotic pool cleaners. Often overlooked, the filter is perhaps the most important part of any pool robot. Filters work via a mechanical process called sieving. The pore size determines what size particles are stopped and what size pass through. The basic filter found on most pool robots is a large pore plastic mesh which is first generation technology. This type of filter is now common on discount pool cleaners. While fine for trapping large particles, it allows smaller particles to pass through.

Micro Pore Innovation Onboard

The second generation type of filter is the Nanofilter™ cartridge, a high-efficiency particulate filter that effectively prevents contaminants from recirculating in the water we swim in.

This micro-pore spun-bonded polyester fabric looks much different. Under a high-powered microscope, you’ll see the individual fibers intersect, creating a tight mesh through which water flows and small particles are trapped. This webbed structure can sieve small micron particles. The deep pleats really grab hold of so much gunk that you’ll be shocked at what comes out of your pool. A pleated filter delivers a second advantage – it has a much larger surface area, capturing more waterborne particles while maintaining a relatively low resistance to waterflow.
