Question about Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum

I replaced the belt on the vaccum cleaner for the brush and it just seems too loose. How do I tighten it? Do you have a diagram I can look at. I lost my instruction booklet.

    We've had the Windtunnel appox. 9 years. Always reliable. Last week I tried to vacuum and noticed nothing was being picked up. I had good suction but still had dirt on the floor. I truned the vacuum over and noticed the brush was not spinning. I took off the plate and noticed the V belt was not spinning. It was like it was too loose. I bought a replacement V belt; had no trouble replacing it. But the brush still won't spin. The new V belt seems too loose as well. I tried to push it as far as it would go into the grooves and still nothing. Do I need a new brush?? Or am I missing something??

Are you certain the belt is on the idler arm and that the spring is still in place? The belt has to sit on the small wheel to provide tension on the belt.

Try using a smaller belt from a different manufacturer. not to much smaller. you dont want it to be extreamly tight just get one slightly smaller and try that. it dosnt have to be made by hoover. as long as it is not wider or thinner just about the same width and slightly smaller. i do it all the time with my vacuums to save money

The belt may look fine but could have lost elasticity. Stretch belts will lose elasticity and should be replaced at least once or twice per year. If the brush strips are worn or frayed it will not pick up properly.

Why does Beater Bar Fail to turn


Per owner's manual
1. Make sure the brush control is set on carpet mode.
2. The brush will only spin when the handle is reclined.
Others:
The belt has worn out and needs replaced. Although it appears okay, stretching is possible, which would result in too loose a grip to turn the bar.
If the belt was replaced, it may not have been pulled tight enough to turn the bar. To tighten on many vacuums, simply loosen the screws on each end of the brush, pull toward the front of the power head and hold while tightening the screws.

I just replaced my hoover belt and it is too loose to make the brush spin. Is there an adjustment to tighten the belt


Greetings from GoVacuum,

The belt is going to be loose as long as the vacuum cleaner is in the upright posistion. If you have the vacuum cleaner with the handle locked in the upright setting, then the belt will be tight around the skinny belt. Once you release the handle of the vacuum cleaner, you can watch as the belt tightens over the roller brush. There are numerous problems with this particular model. We have recorded a very helpful video review of how to replace the belt, and do basic maintenace for this particular model. Hopefully this will help you figure out the correct installation, and other maintenance work you can do yourself.

Here's the video;


If this still does not fix the problem, and the brush is still not spinning, please feel free to email me at chris.jones (at) govacuum.com. I'm always more then happy to try and help you fix the vacuum.

That means that the belt2_bing.gif is starting to wear. When the belt starts to stretch it can't turn the roller brush against the resistance of the carpet and therefore doesn't pick up well. You simply need to change the belt. Here is a link to the belt you need and to the manual:

Brush will not spin any longer


If the brush won't spin at all, it's either the drive belt or the roller beater brush is clogged. Pet hair can quickly clog a vacuum. Turn the unit over and see if the brush will rotate by hand. If yes, it's probably the belt. Also look for debris and clear as much out as possible. You may have to remove the bottom plate and clean the bottom of the unit out. If you do have to go that far, it would be best to replace the drive belt and thoroughly clean the vacuum.

You can download the manual here and it will tell you how to replace your belt. I could tell you, but I won't have diagrams which the manual does. Let me know if you require more assistance.

Brush belt


I noticed the same thing myself. I had set the handle in the upright position, and laid the cleaner on the table to remove the rolloer brush. When I re-installed it I noticed the belt was really loose.

I checked several things before I finally lowered the handle to the operating position. This tightened the belt up, which makes sense when you stop and think about it. If you sit the handle upright to use an attachment you don't want the roller brush working away at your carpet when you don't need it.

Placing the handle upright disengages the roller brush by loosening the drive belt.
