Why won't hoover wind tunnel self-propel?


Hi there! The self-propelled feature is controlled by a belt. Check the belts on your Hoover Windtunnel by following these quick steps.

1. Recline the handle. Lay the cleaner fat and flip it over to expose nozzle base.
2. Remove the screws attaching the nozzle.
3. Check that the belts are not broken, stretched or damaged.

Replace the belts if they are damaged. Hope this helps!

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.

Self-propel switch arm broke off where control cable was attached. Looking for instructions as to how to gain access to that switch arm to replace it.


Greetings from GoVacuum,

This is a farily common repair on this model. What ends up happening is that when someone picks up the vacuum cleaner 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 vacuum 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.

Now for fixing your vacuum, Please click the link below for an excellent tutorial on how to replace this part;

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.

My vacumn wont pick anything up and it wont self propel. I checked the belt - it is fine.


There are numerous things to check.
  1. Check for hose clog
  2. Brush belt has many hairs and doesn't move
  3. Brush belt broken/loose
  4. Vaccum bag is full
  5. Height adjustment according to floor.

Self propelled feature does not work. I replaced


There is a cable from the handle down to the transmission on this machine that breaks all the time or the cable is mounted to a plastic piece that is broken. That will need to be replaced.

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.

Self propel feature is not functioning. have to push the vacum cleaner


Remove the bottom plate and look for broken or loose drive belt to the wheels. Check the wheels for being bound-up with thread, hair and other debris. Make sure that the motor for self-propel runs when turned on.

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
Go Ahead. Use Us.

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.
