Remove the base plate. It is held with screws accessible from under the unit.

Inside you will see the beater bar and the belt.
Remove the beater bar. This is self explanatory once you see inside the power head.
Remove the old belt.

Find a replacement from your local dealer or online.

Replacement is the reverse of removal.

This is a simple job you only need a screwdriver.

Good luck, please rate this answer. Thanks.

You will need to look @ your owners manual to see where the self propell belt is located i am sure yours is broke and need to replace,- it will not be hard to replace-Lance

To my knowledge model F7220900 SteamVac doesn't require a belt. Are you sure that is your model? If you have a different Hoover model you can get a replacement belt here:

You probably should have replaced the flat belt(38528035) also. But the drive belt has a idler wheel(#13) to engage it, is it riding on the belt, if not if may have jammed to one side and able to spring up against the V belt. It could have broke also.

Not sure with having the model number, there may be a number on the belt, like style 7 etc. If no number, get me the model number and I can find out.
