Hoover self propelled U6630900 idler arm lock

My adjustment knob which is connected to the idler arm for CARPET-HARD FLOOR came off. Now the idler arm is disconnected. How do you remove the hood assembly to reconnect the idler arm and thus the adj. knob?

Remove the bottom plate (4 screws), remove belts and brush roller. There may be 1 small screw in the center front of the vac under the brush roller. remove this one. If this is a bagless model you will also need to remove all of the back screws (torx) that hold the lower hose on. This needs to be removed to take the hood off. underneath on each side of the power drive assembly you will have 1 screw, remove them. there is a clip on each side that snaps the front on, push them out with a screwdriver. Then the hood is removed.

There is too much suction even with the hand tools on Hoover wind tunnel. Can i adjust suction somehow?


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.

Move the carpet height control switch to a higher position if the vacuum is difficult to push. If the setting is too low for the carpet being cleaned, the brushes press against the floor preventing the vacuum from moving easily.Set to a medium-high height setting then check.Slide the "Self-Propel" button to the "ON" position if the cleaner does not self-propel. -----------
The self-propel feature operates only when the cleaner switch and the self propel button are both ON. ---------- Try this settings and check.This should help.Thanks.Helpmech.

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:

If this didn't help you, and the problem is still happening, please just use the add a comment form here on Fixya and let me know that you're still having problems. I'd be honored to go through and do some more advanced diagnosing with you.


I hope this we helpful to you. If you did find this helpful, please be so kind and leave feedback for me. This is why repair professionals like myself continue to come back and give free repair advice, to get the recognition of a job well done.

Hoover wind tunnel won't self propel


There are really two reasons why the self-propelled wouldn't work. It could either be the belts on the vacuum cleaner are stretched or broken. The belts on this model control both the self-propelled transmission, as well as the brush roller. Here's a video that shows you how to inspect the roller brush and belts to make sure that they are installed properly and working. Try this repair first, as this is the easier one to fix.


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.

I am trying to replace the cable and actuator on a Hoover windtunnel self propelled vacuum. but I cant get the top or hood off the get to them, I have removed all the screws I can see, roller, belts..what...


Hi there SmartAlec from NelsonVacuums.com.au here. You will need to remove the knobs for carpet/hard floor selection and the carpet height to remove the cover they act as kind of a locking pin. And from memory there are 2 catches on the sides as well that need a flat blade screwdriver to unclip them you can see them when vacuum is upside down on the very edges of the machine (small rectangular holes).
Hope this helps
Happy Vacuuming :)

Brush Roll won't switch positions


The adjustment knob on the hood of the machine is a plastic "arm" that prevents the belt tensioner from tightening up the v-belt so that the roller will stop or start. If the knob is adjusted while the handle is back, it can break the plastic arm off and then the function will not work. This knob should only be adjusted with the handle in the upright position. Usually, if the arm is broken, the roller will still turn when the handle is lowered and will not turn off when the knob is selected to the bare floor. If the brush roll will not switch on , it is usually a problem with the belt(s). You should replace the belts yearly. They can look fine, but be worn out.

Thanks to reddevil6. Sure enough it was the belt. What I did was take off the belt and flipped it over, worked like a charm. Since it was stretched on one side the other side was still ok. Still need a new, but s aved me a trip to the store!
