Our patented design utilizes the motion of your hand to pump and trap debris underneath the screen. The Dirt Lock has a complex Venturi filtering system that manipulates the flow of water in a downward direction. This allows dirt particles to collect underneath the screen without a way for it to re-enter into the clean water. In short, every time you pump your hand in the bucket you are cycling the dirt underneath the screen and replenishing clean water above to help prevent swirl-marks and scratches on the painted surface. KEY FEATURES: Manipulates the flow of water, allowing debris to be trapped under the screen Tapered filters cycle dirt particles underneath the filter and clean water above Flexible self locking rubber tabs lock the unit in the bucket Automatic self adjusting tension for easy install / removal in nearly all buckets Solid industrial grade plastic makes the unit sink like an anchor Chemical & crush resistant Rinse & re-use Dirt Lock pad washer attachment add-on feature Scrub and Pump attachment add-on feature
