In order to replace the belt you have to take the bottom cover and the brusher roller out, and then pop off the top cover. If yours is like mine its green and just a plastic hood. there are two clips towards the back on the bottom if you push those to the inside and pull kind of out and up on the top those should release and the top will come up and then pull it towards the front to remove it. There is a silver peg sticking out. One end of the belt goes around that and the other up through the hole in front and around your roller. just snap everything back together and you should be good to go
