Question about Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum
When we release the handle and let it fall all the way back, the vacuum brush rotates as normal. When we lift the handle to the normal vacuuming position, the brush stops rotating or rotates a little bit and then stops. There isn't as much rotational force when the handle is moved to the normal vacuuming position.
The clutch roller seems to move freely and is in the correct position when the handle is released.
We have replaced both belts already and that did not solve the problem.
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.

The vacuum cleaner is designed for the brush to rotate only when the handle is released for safety resons. I have two of these vacuums and they both operate this way.
