It's the filter that never stops.
The one way Cyclone Filtration system is a passive filter that never needs replacing and does not rely on moving parts, no disposable filters, and requires no maintenance or energy to set up, use, or store. The Cyclone Dirt Trap bucket insert sits at the bottom of your bucket while you wash filtering water non-stop. These designs are defeated by the mere act of dunking the mitt into the bucket, which pushes and pulls water and dirt straight through the vertical openings of the poorly-designed screens. Separating dirt from clean and soapy water keeps abrasive debris off the wash mitt, and therefore off the paintwork for a scratch-less car wash.
