Burnt smell is probably the belt slipping. Even though it looks OK, either the belt needs replacement and/or the roller needs cleaning and/or lubrication at the ends. Try cleaning the roller ends first and then light lubrication with WD40. If belt works, you are done. If not, replace belt.

    Tried all that, burnt smell is gone, knocking sound is not as loud, but still there. I'ld like to try and fix it myself, what next? Or am I dealing with something bigger?

Depending on the motor, either the motor fan broke or the motor has gone bad.

My hoover steam vac is making a horrible noise and smells like its burning


Something may have jammed the brush roller, preventing rotation. This causes the motor shaft to rotate in one spot on the belt, causing the burning rubber smell. Eventually, the belt will break. You need to find what caused the jam and remove it. It would be a good idea to replace the belt as a burned belt is unlikely to last much longer.

what does the really loud noise sound like? Is it a loud, whining sound? if so, the motor may be getting ready to go out. Also check that the belt isn't stuck-though you would smell burning rubber if that were the case.

Burning smell


Something may be keeping the brush roll from spinning freely which may have caused the belt to break.

It may be the belt. Sometime the motor spins but the belt is not spinning with it. This causes the belt to heat-up and burn/melt. The burned rubber maybe what you're smelling and sometime make funny noise and hard to push the vacuum.

That means that the belt is stretched and it is slipping on the motor shaft, that is why it is hot and smells like burning rubber. You need to replace the belt. Here is the correct belt you need:

My hoover elite rewind is making a louder noise and I can smell something burning when I use it. I have replaced the belt but this did not help.


the smell is either the motor or the belt, if motor hope it is under warranty, if belt make sure brush roll spins freely and replace belt, if brush roll not spin freely replace it first

Rubber smell, Hoover


Well it sound like you do need a new belt because of how the smell is you might want to stop using it because the smell comes from the burning and over heated belt my solution would be to get a new belt and that should fix it if you need anything else you know whre to find me.

Sorry it is not belt driven. There is a turbine that drives the brush. You have to remove the top cover to get to it. But if the motor smells hot, then you may have a problem with it also.
