Must be a Hoover, The flat belt may look ok but I am sure it has stretched to the point where under load it won't drive the wheels or the brush roll. Could also be a bad brush roll.

Why won't hoover wind tunnel self-propel?

Hi there! The self-propelled feature is controlled by a belt. Check the belts on your Hoover Windtunnel by following these quick steps.

1. Recline the handle. Lay the cleaner fat and flip it over to expose nozzle base.
2. Remove the screws attaching the nozzle.
3. Check that the belts are not broken, stretched or damaged.

Replace the belts if they are damaged. Hope this helps!

Can't lower handle on Hoover wind tunnel vac U6432-900

Anne, Do you mean that when you depress the pedal on the left side of the machine body that you can't get the upper portion to release into a lower mode? Or are you fully depressing the pedal?? As for the switch for the self propelled mode, that's actually just a small button that you move around in the slot of the handle to select which mode you want to use. It's not actually a switch. If you are fully depressing the handle release pedal and it's not releasing, you should take it to the store where you purchased it, if it was a vacuum store. If you bought it at a big box store, then you'll need to take it to some repair shop that does warranty work, if it's within the warranty period of course.

It might be a slipping rubber belt, is the brush roller moving when you look underneath? If it's a self propelled machine there might be another slipping belt. Friction from fast rubbing rubber can smell like it is burning.

Self Propel doesn't work on Hoover Wind Tunnel

Your self propel wire could be broken. Lean the vacuum back like you were using it. If you stand in front of the vacuum look down and to your left. When you move the selp propel button you should see a wire move. If not then it's broken.

Self Propel wheels not enough power to move machine over carpet.

Sounds like the transmission might need an overhaul. Take it to a local vacuum repair shop and have them look at the transmission.

Self Propelled does not work

if you look below the headlamp of your vac you will find a cable that attach's to a piece called the actuator arm. either this piece is likely broke or the cable itself. always work the power drive smoothly or things will break. also could be that the smooth belt is stretched and will cause the same problem. belts should be replaced every 4 months. good news is all parts above should be under $5. dont let anyone tell you that you need a power drive assy, that usually isnt the case. good luck!!!

Take the brush belt and slip it over the pull into the groove. Then take the flat belt and hook onto the motor shaft and then pull belt over pull and push it around the entire pulley. It can be difficult but after the first time it is easy. You have to push the belt up with your thumbs so the belt will wrap all the way around
