Question about Hoover Self-Propelled WindTunnel Bagless Upright VacuumVacuum

1 Answer

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

It is supposed to be self-propelled and it used to roll very easily, now I have to really push it.  It seems to want to "****" up 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:

Is it necessary to take the vacuum cleaner apart to change the belt on a Hoover Wind Tunnel Self Propelled vacuum cleaner, model UI6460-900? If so, how is that done? If not, how do you get the belt on...


To change the belts, make sure the vacuum is not plugged in. Lay it upside down and remove the screws holding the bottom plate on. Remove the bottom plate, pull the brush roll out noting how the belt goes so you will know how to put it back together. Especially how it goes around the idler pulley. Remove both belts, replace both belts, install the V belt onto the transmission first then around the brush roll and put the brush roll in place. Install the flat belt around the motor shaft and then onto the transmission pulley.

Drive not working on my hover sweeper handle seems very loose


How to Change Actuator on Hoover Self-Propel vacuum Cleaner - Step by Step This is a notorious problem for the Hoover WindTunnel Self-Propelled Models. What happpens is that the handle of the vacuum that controls the transmission is controlled by an actuator arm that is attached to a cable that runs down through the machine. The poor design of this self propelled system is design in such a way that if you pick up the vacuum using the handle (this is natural way to do it, I'm guilty of this as well), it puts too much strain on the actuator arm that controls the self-propelled mechanism, and causes the nut, washer, and screw to strip right out of the actuator arm. This explains why your handle is so loose. You may verify this by looking at the gap between the upright body, and the lower agitator housing, right where the vacuum pivots when you step on the handle release pedal. You should see when you move the handle up and down that the cable and nut are the only parts moving, and you should be able to see where the nut did sit inside of the actuator arm before it was stripped. The good news is that this is a relatively inexpensive part, and the repair is really not that difficult.

I will explain step by step, and include pictures so that you may see how to replace the part that's broken.
Always be sure your vacuum is unplugged from the electrical outlet before performing any kind of service!
Tools and materials:
Torx bit or driver size T-25
Flat blade screwdriver
Phillips screwdriver
Actuator arm – Hoover part number 43143046

Here's the picture of the part that probably needs to be replaced.
hoover-self-propel-fix-7-300x132.jpg
Step 1. Place your vacuum cleaner upside down with handle resting on the floor and brush roll housing resting on a work bench.
Remove 4 screws from rug plate and set rug plate aside.
hoover-self-propel-actuator-fix-1-300x225.jpg
Step 2.
Remove power drive belt, brush roll belt and brush roll.

hoover-self-propel-actuator-fix-2-300x225.jpg
Step 4.
Remove 6 screws as shown. Also remove duct hose cover and small plastic section that was under brush roll in upper left corner.

hoover-self-propel-actuator-fix-3-300x225.jpg
Step 5.
Place vacuum right side up on top of work bench with handle all the way back. Using a flat blade screwdriver; gently pry the top cover away from the bottom housing in the area shown by(#1) arrows. Leave the 2 adjustment knobs(#2) in place.

hoover-self-propel-actuator-fix-4-300x225.jpg
Step 6. If the self-propel adjustment cable HAS NOT broken away from the actuator arm, proceed as follows; mark the position of the cable(#1) in relation to the cable retainer with a black magic marker to avoid having to readjust the cable position. Remove the screw(#2) (usually a Torx T-25 size screw) and cable retainer. Next, using a flat blade screwdriver; slide the ‘C’ ring (#3) off the metal post. Bend the metal bracket up off the post just enough so you can lift the damaged actuator up and off the post. Slide your new actuator arm back over the metal post. Slide the ‘C’ ring back over the post.Lock the self- propel cable back in place with screw and retainer. Test to ensure the power drive is adjusted correctly; CAUTION, YOU ARE ABOUT TO COME VERY CLOSE TO MOVING MACHINERY, NO NECKTIES, NECKLACES, LOOSE SHIRT TAILS,UNACCOUNTED FOR TOOLS OR CLUMSY FINGERS ARE ALLOWED FOR THIS NEXT STEP!!! Reinstall the power drive belt, plug your vacuum cleaner back in and turn it on. Check to make sure the handle is in the neutral position; observe that the power drive is NOT moving. Push the handle slightly forward. You should see the power drive wheels move in the forward position. Pull the handle back, you should see the power drive wheels move in the reverse position. Some finer adjustment may be necessary.
If the power drive cable has broken away from the old actuator; just try to get the new actuator arm as straight as possible. Using the handle and while observing the cable moving back and forth through the retainer area; move the cable all the way forward, then pull it all the back, try to gauge where the middle of the forward and reverse position would be and lock the cable down. Perform testing procedure as in previous paragraph. Again, some fine readjustment may be necessary.

Install self propelled belt

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Usually the self propelled vacuum have 2 belts and you should replace them both 2 the same time 1st the self propelled belt and then the brushroll belt. Normally you would hook the belt on the pulley side of the brushroll or self propelled unit and then stretch the belt onto the motor pulley side of the motor using a belt puller or a screwdriver with a bend on the end for pulling and or stretching either belt onto the motor pulley. If you have a problem please feel free to contact your local vacuum cleaner 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.
Thanks, Don the Vac Man

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.

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.

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.
