The switch to turn the brush roll on and off is on the top cover of the nozzle housing

This sounds like the switch is sticking closed and starting to fail. Replace the switch with a new one.

Filters might be clogged which will overheat motor. Clean and replace them frequently

Wait 30 minutes and try again, there is a thermal overload switch that resets itself.
Clean all three filters and see what happens.

You probably need the switch replaced. It's fairly simple to do youself, and it is a known problem with these vacuums.
You can order the switch from hoover for about $10

This is a common problem in homes with long hair or pets. A vacuum has the nastiest job in the house. The hair will travel to ends of the brush continually and cause problems on any vac however better quality vacs have thread stops around their bearings or at the end of WOODEN brush roll. You can clean some of the brush with scissors or a utility knife from the outside of the nozzle housing but you must inspect the head continually or you will end up with a ruined brush roll. THAT OR A HAIRCUT FOR THE OFFENDERS.
This is only part of the fix, thew brush will need to be removed thoroughly cleaned from time to time. A wire brush also helps to remove it when you cut through it.

move the height adjustment up a little

These motors have a fuse incorporated in the field winding and it sounds like that blew. These motors sometimes overheat at the front bearing and the bearing will melt into the plastic housing. This will cause the fuse to blow. It sounds like that's your problem. You can remove the motor by removing the three screws on the bottom of the powerhead and then check the front bearing for any bubbling or blistering in the plastic housing. The shaft of the motor should turn easily.
