Two curved clips and four small Phillips screws make replacement easy. This setup is pretty hard to screw up. New brushes work great! If your vacuum cleaner is similar to mine. EUUUUU! Grab some water and some rags to clean everything before installing the new brush. I found that a coat hanger is also good for removing some stubborn bits. (okay I changed my brush a few times) Wow I always wondered where the other two dogs went!
