I had the same problem with my Hoover s3639. The cord rewinder started squeaking, and retracted less and less of the cord each time, until it finally stopped retracting the cord at all. Here is what I did. I hope it will work for you as well. Open the covered tool storage and remove the tools. You should see three screws. Unscrew the screws. Remove the cover. You should see the motor for the vacuum and the cord rewinder. Between the vacuum motor and the white wheel where the cord is, you should see two brass wheels that turn into each other in order to operate the cord rewinder. Spray a small amount WD-40 between the two brass wheels. This should solve your problem.

change filters. the filter inside the unit and the one on the side needs to be changed once a yr. (these are not to be washed, only the side filter if foam can be washed ). also flat belt change every 6 months and the v-belt once a yr.

SOURCE: How do you change the Hoover wind tunnel belts?

If you turn the vacuum over there will be (4) screws that hold on the base cover for the roller brush. Remove the screws and the cover and you can get to the belt(s). You can get replacement belts here:
