Self propel will go foward, but will not reverse. Seems like handle is all the way extended.

    Thanks for the reply. I did find that the acuator arm was broken where the cable connects. Seems that I have been picking the machine up at the handle and causing cable to put to much pressure on the plastic acuator. Replaced part for about 8 bucks. Works fine now. P.S. Now I will pick machine up with the proper handle now.

My machine wont go forward or reverse. The handle wont move up or down but just a little which slightly moves the actuator piece. The switch wont disengage to the off position either. I have tightened the cable and loosened it also. No change. What am I overlooking? This is really frustrating.

There is a cable that connects to the handle and goes down to the powerdrive transmission. It is visible at the actuator arm on the drive if you look at the bottom of the handle where it pivots on the main housing. It will be on the right hand side, front corner of the handle bottom. You should be able to see the cable connected to the arm of the drive and will move back and forth with the top handle. Sometimes, they break at this connection. The cable may be frayed and broken, or the acuator arm may be broken where the cable connects.
This could also be a simple worn belt problem. The roller is always rotating in a direction that pulls the machine forward and if the belt is worn, the roller will turn sluggishly but still enough to pull forward, but the belt also drives the transmission and a worn belt will not have the capacity to overcome the forces involved to propel the machine backwards. Always change the belt(s) yearly.(on average)

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.

Just put handle on windtunnel u6401-9rm and the self propelled switch will not flip into self propel mode. is there an adjustment on the self propel part?


When installing the handle on this machine, you must be sure the on/off switch and the self propel button are both in the OFF position. The actual switch inside must also be OFF, and the metal fitting on the end of the power drive cable should be between the two lines molded into the plastic. After it is re-assembled, it is sometimes necessary to wiggle the handle up and down a bit to engage or disengage the drive button.

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. 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.

Hoover Self-Propelled WindTunnel U6436-900 cable problem


The flat belt should be changed if it has been longer than 9-12 months. Next I would remove the upper handle to inspect the top section of the control cable, sometimes it fray's and has a sponge feel (no positive control) to self propel. To set this adjustment, it is best to do withthe hood off of the lower section. I would also look at the cable jacket in the foot to make sure it is under the metal clamp. It must be under the clamp to work properly. To get it under the clamp loosen one hold down screw at the top and one in the back of the vacuum, remove clamp screws and put jacket into position and then secure all screws. Now set the adjustment, Install upper handle and set self propel to off. loosen cable from arm in foot with torx screw. manually move arm until the clutch is off both drive pads. This is a visual adjustment. then secure and reassemble vacuum.

Brush won't turn and self propel doesn't work (by 2 users)
Posted by brucelk on May 24, 2008
I have replaced both the v-belt and the larger belt with Hoover brand belts and the brushes still don't turn properly and the self-propel function doesn't work. It seems that when I lower the handle all the way down toward the floor it works fine, but no one can vacuum this way. Is there an adjustment to belts to tighten them up? Otherwise I have to get it in to the only repair shop in town which is an hour's drive.X

1 Other User Has the Same Problem Comment by chartsell, posted on May 29, 2008 I have replaced both the belts as well. I have tightened the screws as someone else as suggested. The brush still will not turn unless you lower the handle almost to the ground. Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Hoover U6437-900 / U6439-900 Windtunnel Vacuum. It is not so much the belts, the 2 belts are only part of the solution. The average belt change is every 4 to 6 months as a rule and to change them @ the same time. The Hoover Self-Propelled works on when the handle is lower to a comfortable position then the self-propelled drive may just need and adjustment. There is a self-propelled rod that controls the self-propelled feature and it either needs adjustment or replacement or the part that hold it may be broken but either one can be fixed. So feel free to contact your local vacuum cleaner dealer with questions. 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.

Hoover Bagless Windtunnel - Self Propel feature not working


I have the same problem with ours. If you lift the vacuum by the handle it breaks the lever on the transmission. You can find a replacement cable and lever on line for about $16.00 it is somewhat involved to repair but can be done by someone with mechanical ability. You can try and find a repair shop but be careful, they sometimes tell you the part is not available and try to sell you something else. I think they should be able to do the job for aprox. $80.00, but they may want more. I did it myself plus the height adj. knob for $24.00
