Brushes won't spin on hoover steam vac ls (by 6 users)

I have the SteamVac Dual and there's a screen on the underside of the unit. It's beneath the brushes and it's red. You have to pull and wiggle it to get it out. With the machine unplugged, lay the unit with the handle on the floor. In the owner's manual ( http://www.hoover.com/pdfs/manuals/F7222900.pdf ) this is shown on page 10 figure 3-2. Clean that screen.
If they still won't spin, then take the brushes out. Again, with the unit on the floor, you simply grab the unit firmly and pull towards you. It's much easier to remove than the screen. I took the brush unit outside and blasted it with the house. You'll have to pull out whatever fur balls are clogging it but eventually you'll see that the brushes spin freely with the water squirting on them. Plug the brush unit back in and - in my case - they started spinning.
