Most likely the flat belt has stretched enough so as to not turn the pulley that in turn turns the brush roll using a V belt. Also there is a small idler wheel, if hook up, then it won't engage the V belt.

To change the belts, make sure the vacuum is not plugged in. Lay it upside down and remove the screws holding the bottom plate on. Remove the bottom plate, pull the brush roll out noting how the belt goes so you will know how to put it back together. Especially how it goes around the idler pulley. Remove both belts, replace both belts, install the V belt onto the transmission first then around the brush roll and put the brush roll in place. Install the flat belt around the motor shaft and then onto the transmission pulley.

Good afternoon,

You did not specify your exact model, so I assume you are referring to the Hoover Model# U6616-900.

The handle is attached to the unit by 4 screws. Below is a picture for reference (in this case, you would do the opposite to remove the handle). Once the handle is removed, this should give you a start in accessing the wiring for the unit.
For further reference, please review the manual for this unit:

I hope this solution helps. Please rate if you can, or ask for clarification and I'll be happy to assist.

Some Wind Tunnels by Hoover have a poor design in the switch on the handle. Sometimes the switch does not turn on all the way and will stop running. Other times you can't turn the unit off.

Hey there! The thermal protector sensor can not be replaced. It protects the vacuums motor from overheating and burning out. If the vacuum is overheating, follow these quick trouble-shooting steps.

1. Remove the hose from the vacuum from both ends.
2. Use a broom stick to gently loosen and remove any clogs from the hose.
3. Remove the bottom plate and the brushes. Use a wooden spoon to gently break up and remove any clogs from the lower hose.
4. Clean the pleated filter inside the dirt cup by tapping it against the trash can until the dirt stops falling. This filter should be replaced at least once a year.
5. The pre-filter can be cleaned with a brush and then rinsed with water. Allow 24 hours to air dry outside the dirt cup.
6. Clean the secondary filter located behind the grill in the bottom of cleaner cavity. Remove the screw, and grill to access filter.
7. Rinse the filter in cold water with a mild detergent to clean. Allow 24 hours to air dry outside the vacuum.

Following these steps should stop the cleaner from overheating. Hope this helps!

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.

Hi, it's Jeremy from Crucial Vacuum.

If there is too much suction, adjust the nozzle control knob to a higher setting. The knob is located on the front of the vacuum at the bottom. For optimal cleaning efficiency a low setting should be used for most types of carpet and for hardwood floors, tile, and deep carpets use a higher setting.

Remove the handle assembly by removing screws and sliding off. Remove nozzle housing cover and unscrew fastener at end of cable. Pull cable from handle end out of cable sheath. Slide new cable into sheath and fasten at bottom as it was before. You will need to adjust the cable to the proper location so the transmission works properly in both directions.

I had the same problem - I found the elbow behind the brush was plugged. You have to remove the floor brush, canister, and hose. Look into the pipe from the top, looking toward the floor brush. Most likely, that's where its plugged. Also check the hose - run a broom handle down the hose.
