To clean the roller, you use the specially designed curved scraper to scrape off any excess paint from the roller cover back into the can or paint tray. Then insert the messy roller into the Rolla Cleana while it is still on the frame. You can place the roller frame into the paint tray and slide the Rolla Cleana over the roller cover so the paint spills into the tray and not all over your hands.
Secure the frame into the locking hook, then attach the hose to the snap on connector and turn on the tap.

Slowly increase the pressure. You can see the paint coming off the roller cover.

Turn off the tap, remover the roller and the job is done. No mess, no fuss.
