The Roller Ready is a one-piece tool that is simple and straightforward. This handy tool is designed to fit seamlessly onto any standard drill making it easy to use with the equipment you already have. Once the Roller Ready is installed on a drill just slip the tool into a dirty paint roller. Turn on your drill and let Roller Ready do the work for you. The centrifugal force will spin off any excess paint. Then submerge the roller into water and let the spinning action in the water clean the roller.
