There is a height adjustment on these vacuums and they are set to adjust in the "handle up" position". It will appear that the adjustment is doing nothing when the handle is up, but the setting will take affect when the handle is lowered.
You can check the brush length with a pen or pencil. Turn the machine over so that the brush is visible and run the pen or pencil flat across the bottom plate. Any where the brush is extending outward, your pencil should contact the bristle. If not, then the agitator should be replaced.
Also, check to make sure that the agitator is rotating freely and that the filters and bag are allowing for adequate suction. The machine will only pick up if the air flow is sufficient.

How to replace power cord on Hoover Windtunnel...
Posted by SaxTeacher on Apr 15, 2008
The cord on my Hoover Windtunnel upright vacuum is damaged from having been run over while vacuuming. I purchased a replacement power cord, agitator brush, belt, and filters from the Hoover web site.
I have installed the new brush, belt, and filters. I'm ready to install the replacement cord, but I can't figure out how to access the interior part of the vacuum! I tried removing many different screws but none of them seemed to give me access to the necessary area. Any help would be appreciated!
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.

Depending on where the cord comes out, you may want to check the owner’s manual for the exploded view of the cord area. Usually the cord comes out of the handle and there should be handle screws to release the existing cord and when you replace the cord mark the wires so that you will replace the new cord in the same manner. If it comes out of the body of the vacuum there are recessed screws that will let out into the vacuum to replace the cord. You don’t want to exceed the repairs cost to the price of what you paid for it. The decision should be yours, example: if the repairs costs are $200.00 and you paid $279.99 then @ that point you would have to decide if the repair costs are worth or do you want to pay the lower cost of repair and continue on. Just a suggestion... You may want to check with your local vac dealer. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

Sounds like you have a clog, which is a fairly common problem with these.
Check the air inlet immediately aft of the brushroll for clogs, then make sure the main wand and hose are also clear. If you have the machine on, check at the end of the hose for suction. This is a fairly common problem for all uprights with tools on board. Their airflow is very low, so they tend to clog up easily and then overheat the motor.

1. Remove the 4 screws holding the bottom plate.
2. remove roller and old belt
3. install new belt on motor spindle first and then on roller.
4. pull roller, stretching belt, set into roller cavity.
5. turn roller by hand to center belt.
6. reinstall bottom plate.& screws

I have a Windtunnel S3765 with the same problem - and it has very little use so I'm confident it isn't wear. I find that the wheels do not raise the agitator brush sufficiently high to reduce the drag caused by excessive contact with the carpet. If I raise the front a bit the brush spins as it should. It also works if I take the housing apart and use it without ..... but this is tricky.
Unfortunately I haven't figured out a way to hold it up efficiently. I am toying with afixing something to the bottom of the housing to raise the front enough to give the brush a little more room.
