Man my vacuum cleaner is really starting to piss me off. I have a bissell and I just bought a belt for it cause the last one broke, then I needed to get filters cause the old ones were shot. Well I go and put the new filters in today and use it and the damn thing starts smoking and catches on fire. So I look and it ends up that the brush assembly is shot because the bearings are worn out. So since it wasn't spinning and the belt was, friction being the end all of most things (including motors) caused the damn belt to catch fire. Now I need to buy a new brush and bearings and another belt. By the time i'm done I mine as well just bought a new damn vacuum.
