My Bissell Cleanview Bagless vacuum makes loud grinding noise.

The ends of the roller have something wrapped around them.see if you can pull the ends off so you clean the caps and bearings

I have a Bissell Pet Hair Eraser and last week I smelled a burning rubber smell then the loud noise started. It was the roller bar. I talked to a man at our local vacuum parts store and he said those rollers are not going to last. The bearings go. The old one doesn't look like it's beat up or anything, but once you compare it to a new one, you will see a difference in the ends. I took my old belt and he said it was stretched out, also, so I bought a new one of those also. I just installed both and the noise is gone!
