Question about Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum
Sounds like your motor bearings are going bad. This is generally indicated by the motor overheating, and the heat transferring out through the motor pulley, which is where the belt attaches. So, your machine is overheating, melting the belt, and then tripping the thermal cutout. When it cools and you restart it, the belt is no longer functioning due to being melted, and this would make it not pick up on carpet. If you look at the motor pulley and it is turning blue: this is indicative of overheating.
The other possibility is that there is a clog, which is also causing your motor to overheat; so before you throw it away make sure all of your air pathways are clear.
The fact that you've had it 8 years is somewhat remarkable, however, since most vacuums of this type are averaging a 3-5 year lifespan. (And half that for bagless.)
So, check for clogs, and if it's not clogged, you're probably due for a new machine.
