Violent shaking and very loud noise from floor nozzle
My vacuum makes a horrible loud noise and shaking that comes from the floor nozzle. It has been getting worse to the point where I can't turn it to the carpet mode without it violently rattling and making a very loud noise. I have already replaced the belt on the vacuum, but that did not solve the problem. My theory is that either: 1) my original belt and the replacement belt were both too loose, which causes the rotary brush to shake, or 2) I noticed that the black cushion part in the clear casing around one end of the rotary brush (the end on the belt side) has a groove in it, like the black cushion has rubbed away or burned away, so maybe that could cause the brush to be less stable and shake? (see picture) Curiously, the worst of the noise seems to be coming from the other side of the vacuum, not the side with the belt. I'm wondering if anyone has any advice. I am not sure what parts I would need to replace to fix this, since I already replaced the belt.
@strongbow Thank you for your reply! I looked at the rotary brush and saw that one of the end caps on the brush (the side with the belt) has cracks on the outside and is also torn up slightly on the inside (see attached picture). Do you think that this could be causing the issue? Do you know if I purchase a replacement rotary brush, would it come with the caps at the end of the brush or is there a way to just purchase the caps?
Also, I noticed the belt seems very loose compared to how tight I would expect a belt to be. (Even though this replacement belt is the same size as the first belt I had.) I can easily slide it off the gear and it doesn't have much tension. Do you know how tight the belt should be and if this is normal for this type of vacuum? (see attached picture)
Update on final solution: I replaced the rotary brush with a new one and it has solved my problem. No shaking or loud noises.

Those white end caps have passed the end of their life. In the last pic you can see its ovalled. As for the belt tension, that is probably caused by those white bushes. You have to Google the brush and see if you get the bushes with it. I looked and couldn't find any. You may be looking at a whole new head if you can't find any. Maybe email the manufacturer directly and see if they can help with the parts.
@strongbow Thank you for all of your help! I will try to get a replacement rotary brush that comes with the end caps and hopefully it will work smoothly after that :)
same problem ,thanks for your help
