The flat belt probably has come off, may need to replace it if it hasn't been replaced in a while. May look ok, but am sure it has stretched.

The vacuum is not rolling easily. It "drags" on the rug.


Hi There,

When a Hoover Windtunnel becomes hard to push, this usually indicates that self-propelled has stopped working.

When this stops working, it can be caused by several things. The first, most common problem is that the belts have either broken, or stretched to a point where they no longer engage the self-propelled mechanism. In order to verify this, simply make sure that the machine is set to the Carpet setting, turn the machine on, and turn it over on it's side with the handle release pedal reclined (make sure it's not in the upright position). Is the brush at the bottom of the vacuum spinning? If no, this definitely indicates that your belts have gone bad and need to be replaced. There are two belts on your machine, one controls the brush, the other controls the self-propelled mechanism. We've shot a helpful video that walks you through step by step on how to replace the belts.

This is by far the most common problem that we see on your particular model:


The other problem if the belts are installed properly that would cause the self-propelled wouldn't work would be the self-propelled actuator arm. There is a cable that starts at the handle of the vacuum, and runs all the way down to the floor head of the vacuum that controls the transmission. As you pull backwards on the handle of the vacuum, the cable pulls this actuator arm backwards, which then turns the wheels backwards, and when you push forward it turns the wheels forward.

The problem with the way it's designed however, is that if you pick up the vacuum cleaner by the handle of the machine rather then using the carrying handle on the back of the vacuum, it causes too much tension on the actuator arm, and will cause the cable to rip right out of the arm.

This is a VERY common problem on this model. To check and see if this part is broken on your vacuum, step on the handle release pedal so that the handle is in the vacuuming position, push the pedal a second time so the machine lays flat on the floor.

Now if you look right behind the height adjustment switch, and the rug / floor switch where the floor part meets the upright part, you should see a cable that connects into the actuator arm. Pull up and down on the handle and look for movement. Is the cable loose with only a nut attached to it, or is it resting in the actuator arm?

Here's a very helpful link that shows you exactly how to replace the actuator arm:

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.

I have a self propelled Power Supreme vacuum. It


Most common cause is fibre / hair in the roller and brushes. remove base cover and remove fibres . Remove screws and use small scissors to cut along roller / brush then pull gently.

Brush roller on Hoover upright stops turning


There should be a belt tensioner for the V belt, maybe it is not contacting the belt when you tilt the handle back. If this is less then 1 year old, then it is under warranty, take it in to a warranty servicer for warranty repair.

Hoover wind tunnel upright self propelled. U6473-900. Brush does not work. Heard it was a 'brush controller' problem and can be fixed. Please tell me how.


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.

Brush roll wont turn


Might be that the the idler wheel is stuck and not engaging the V belt. If you look down just past the V belt you will see a black roller, it needs to be against the belt. It is either stuck or the asm. is broken.

Hoover windtunnel Self-propelled - brush roll stops


There is a idler wheel that will drive the V belt, sometimes they jam and you just have to reach in, push and make sure if comes in contact with the belt. Alot of times tho it is the other flat belt, 38528035 that will stretch and can cause you to have problems with the brush roll not turning.

Edge of carpet went into carpet; was removed, but now all rollers on the unerside don't function.


You didn;'t say what the problem is, but I assume that the brush roll is not turning. Take of the cover over the brush roll, then you can get to the brush roll and the belt. The belt probably came off or broke. Best to replace the belt.

Self propelled wind tunnel vacum will notpropell itself


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.
