I took the rubber strap off a pair of safety goggles and trimmed it to fit the vacuum cleaner.
I then super glued the 2 ends together, let it dry and kept on vacuuming. don't be stingy with the super glue, and make sure the glue is dry before putting it back on the vacuum otherwise it'll get stuck to the vacuum, which is no good
this is a cheap, quick and easy way to fix a vacuum using just a rubber strap and super glue!
I would have just glued the broken belt back together but it was too badly messed up.
