Question about Hoover F7458-900 Upright Vacuum
We were using the cleaner, emptied the waste water, then tried to turn it back on. There is a buzzing noise (sounds like hair clippers) but no function of the brushes or sprayer. All of the tanks are seated properly, and we cleaned the brushes. It does this in all three brush positions. At one point, we moved the machine from one room to another, and it started up correctly, but when we turned it off to move a chair, it quit working again. It was only on for a few minutes at that point, and the motor was not especially hot.
The belt for this machine is very specific and only one size fits. It is not uncommon for vac shops to sell the wrong belt because the proper belt is not available from normal supply houses, so they will substitute something they think will work.
Also, assuming you do have the right belt, check the tension arm that drops down on the v-belt when the handle is brought back. This arm has a wheel/bearing with a plastic "tire" or trim that rolls on the belt to tighten it. Sometimes, this tire cracks and falls off and then the remaining bearing won't have the necessary tension to tighten up the belt.

What I had to do was take apart the vacuum head...which is very confusing, and the manual doesn't tell you how...the "secret" is to use a flat screwdriver to pop out the little wheels...there are two other screws "hidden" beneath them. Be careful as this exposes all the electrical parts as well - make sure you're unplugged! : )
