Question about Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum
This is definitely a problem with your belts. This Hoover Windtunnel Self-Propelled models has a poorly designed belt system that frequently goes bad. Most customers will have to replace the belt once every 8-12 months, some even more frequently than that.
There are 2 belts on this machine, and it's recommended that you replace both belts at the same time. If you just replace one of the belts, this will cause the other belt to go bad quicker.
If you don't already have the replacement belts, here are links to these belts through us:

Replacing the belts is pretty straightforward, but the new one is too loose also, like the worn out one, and the brush still won't move. I am coming to despise this unit.

After checking a myriad of answers to this particular question, I suggest you query "new actuator arm for self-propelled Hoover Wind Tunnel" it's part number 43143046. There's a very good video; hopet I'm allowed to post the link here. https://youtu.be/K722IsUxjYM
When new belts don't fix the problem of the brush no longer turning, it's often the actuator arm or the cable that connects to it.
One place I checked said that this problem occurs when machine picked up by propel handle it rips the nut and bolt out of idler arm causing it not to work.
