Hi There,

Here's a step by step guide that will explain in detail how to remove the top cover on your Hoover. The repair was written for a different problem then one you're experiencing, but you can follow along step by step to see how you can remove the top cover.

If you haven't already purchased the actuator arm, here's a link for you to the part on Amazon
Hoover Windtunnel Self-Propelled Windtunnel Actuator Arm

Here's the repair guide:
Step 1. Make sure that the vacuum is unplugged. Turn the machine upside down so that the brushes are facing upwards. I find the easiest way to do this is to put the brushes on top of a counter top or work bench with the handle of the vacuum resting on the floor. Remove the four screws that hold the bottom plate in place. Remove the bottom plate, both belts and then the roller brush from the machine:

Step 2. There are 3 screws that hold the top brush cover in place that need to be removed. On the right side the screw is down below the transmission to the right. There's also a screw in the agitator tray, in the middle that needs to be removed. NOTE: This small screw in the agitator tray is only present on some models, you's may or may not have this little screw, but all models will have all other screws circled. I have circled both screws that need to be removed:


a2c6df2.jpg
The screws on the left side that need to be removed are also circled. One screw holds the upper brush cover on, and the other two screws secure the hose in place. Remove all three screws as well as the transparent hose cover:


e00d104.jpg
Step 3. After all of these screws have been removed, there are two clips that are the last things holding the top brush cover onto the vacuum. Use a flat head screwdriver to push these clips off on both the left and right sides. The right side clip is near the pulley that the flat belt2_bing.gif rides on, and the left side clip is next to the internal hose.

Step 4. Once both of these clips have been pushed so the unhook from the lower agitator housing, remove the top cover.

Once you have removed the top cover, here's a link to a guide that will show you how to replace the actuator arm itself:

I hope that this information helped you fix your vacuum cleaner. If you have any follow up questions, or need clarification on something, please feel free to use the comment box here on the Fixya repair page, and I'll be happy to answer any of your questions.

Check the plastic part, which the the self propelled cable is attached to. (release the handle, tilt it back. You should be able to see the cable attached by a screw to a black plastic arm.) It is either broken or the cable is lose.

Self propel not working


Make sure the replacement belt was the right one/size.
Make sure the self propelled is on at the handle. If you replaced the flat belt and it still pushes hard the most common problem is a broken power drive cable or actuator arm. Put the handle down and move the power drive handle forward and backward. If it moves freely watch by the headlight for the cable to move the actuator at the base. If the cable is in tact it should move the actuator. If it is broken the actuator will not move. If the actuator is broken the piece of plastic holding the cable will let the cable slide or it may be broken off completely. Replace whichever is broken.
If the cable system is ok and the belt is correct you may have a bad powerdrive assembly. I will include links to correct replacement parts.

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.

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.

Self propel unit broken


This is a farily common repair on this model. What ends up happening is that when someone picks up the vacuum cleaner2_bing.gif by the handle of the machine, which on this model also is the controller for the self-propelled transmission, it places too much strain on the actuator arm of the vacuum2_bing.gif cleaner.

You can do the best to try and not pick up the machine by the handle, but instead using the carrying handle on the back of the vacuum cleaner, this is distribute the weight much better, and even make the machine seem less heavy, and this will also prevent the actuator arm from breaking again in the future.

We have also put together a very helpful video for your vacuum cleaner on how to replace the belts. The belts on this model are also a frequent issue we see with these self-propelled Winddtunnels. In fact, for best results you should change the belts once a year, even if they are not broken, because they do heat up and stretch to a point where they don't work as well as a new belt would. The video also explains how you can maintain the roller brush will help you get the longest life possible out of your belts.

Self Propelled does not work


if you look below the headlamp of your vac you will find a cable that attach's to a piece called the actuator arm. either this piece is likely broke or the cable itself. always work the power drive smoothly or things will break. also could be that the smooth belt is stretched and will cause the same problem. belts should be replaced every 4 months. good news is all parts above should be under $5. dont let anyone tell you that you need a power drive assy, that usually isnt the case. good luck!!!
