Change belts on a Hoover Power Drive Wind Tunnel Series 900 vacuum

Its usually located underneath the body of the unit, turn it upside down and you should see the beater brush. You need to open the bottom cover to get at the brush and drive belt.

First of all you have checked to make sure you are plugging into a outlet that has power correct ? If you have power at the outlet then when you activate the switch does it make any noise at all ? If not you may have a defective switch. If it's making a noise you may have a broken belt or something jammed in the brush.

I hope this helps.

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:

Below I have listed a link to the manual which has instructions and a link to the V belt you need.
