Hoover Ultra U6430-900 brush & propel problem

Brush wont turn until you push the handle way down towards the floor and at that point i think it turns because the front of the vac is off the ground. saw the self propel cable was detached from the lower unit so I pushed the wire holder back into the slot shapped like a "c". now the self propel works but that doesnt until the brush turns. i changed the v belt, didnt fix anything. i am going to order the flat belt and a new brush, does anyone think the flat belt is the issue? unit is about 4 yrs old. appreciate any help.

The flat belt is the problem, it has to be tight so it can turn the drive and also the pulley for the V belt.

How do i disassemble my hoover f7220


Hi there! The tanks, brushes, nozzle and handle can be removed from the cleaner by following these quick steps below.

1. To remove the clean water tank simply grasp the handle and push down on handle to unlock it, then pull the tank out by the handle.
2. To remove the dirty water tank, slide the latches open located on the sides of the cleaner that hold the tank to the base of the cleaner. Grasp the handle and pull up and off.
3. For brush removal, with the handle in the upright position, tilt cleaner back until handle rests on floor. Grab brush assembly and pull firmly.
4. To remove the nozzle, with handle in upright position, tilt cleaner back until handle rests on floor. Pull tab at rear edge of nozzle and pull forward to remove nozzle.
5. For handle removal simply remove the handle screw and lift up on handle.

Disassembly beyond this point is not recommended. Hope this helps!

Can't lower handle on Hoover u6432-900 so can't clean floo


usually theres a plastic pedal you would step on to release the handle.... first thing i would try is pushing up (foreward) on the handle and try pressing the pedal .if the pedal wont push down at all then something might have gotten jammed down in it..... at which point you'd have to do a bit of fiddling around with it to see whats keeping it jammed up.....also... there could be something stuck in there thats keeping the handle from being able to move down.... as for the self propelled part.... it probably wont work untilthe handle is lowered... hope this helps

Windtunnel 721.35820500 not picking up


I had the same problem - I found the elbow behind the brush was plugged. You have to remove the floor brush, canister, and hose. Look into the pipe from the top, looking toward the floor brush. Most likely, that's where its plugged. Also check the hose - run a broom handle down the hose.

I have the Hoover, self propelled vacuum. I have only used the self propel function a few times, but our babysitter used the feature and now the vacuum only works on the highest carpet setting. The middle...


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:

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.

Why is self propelled not working on my hoover windtunnel


Hi there SmartAlec from Nelsonvacuums.com.au here. Actually the brush belt needs to be tight as well for the self propell function to work. However once you change that if it is still not working it could be the drive mechanism itself. You can test this by laying the vacuum flat on its belly so you can see the brushes. Turn it on and push the handle down (as if you were actually vacuuming). This should get your drive wheels going they are two wheels about 3 inches away from your brushes. If they are not turning then you need a new drive mechanism. If you are in australia i can get you one through our website above.
Hope this helps. Happy Vacuuming :)

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

OK
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.

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.
