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

1 Answer

Hoover Windtunnel spits dirt back out the back

I have checked every filter and the belt. My Hoover Windtunnel U5767 will not pick up from the bottom, although the hose cleaner has a great suction. I am at my wits end with this thing!
Any help is appreciated.

    Thanks. I changed the belt which was somewhat stretched but found the problem in the very bottom of the unit where the hose goes into the unit. There was a very large amount of "stuff" clogging is up. Thanks.

    The attachment hose works fine but the floor vac picks up and blows dirt and dust out the back.

Your problem sounds to be an obstruction in the foot (lower body) of the windrummel. Most all windtunnel's have a second cavity for suction to go over the top of the roller. When you remove the bottom plate, next remobe the belt and roller, under the roller will be a removable cavity, take it out. remove the dirt and clean out any debris. also check the suction path connecting hose. if your belt has not been changed in the last 12 months, I would recommend changing that as well.

Is the belt still intact?
Does it has a wand tool, normally they are connected at the bottom of the machine,if it gets plugged up with gunk, that will greatly reduce your suction.

I have the bagless hoover windtunnel and it doesn't pick up anything and it is very hard to push. Changed the belt and The rollers are spinning and the filter has been changed. What else can I do?


It sounds like there are dirt and hair wound around the wheel axels cousing them not to spin freely. You have to remove all hair and carpet fiber. Then drop a drop of lubricant oil on the axel.
Change the filter.
You should even Check the floor nozzle for clogged dirt.

Greetings from GoVacuum,

There are two things that you should check on this vacuum after running it without a bag inside. The first thing you should check is the filter that is underneath of the vacuum bag. This filter is underneath of a bracket, and the bracket can be removed by pulling straight up on the bracket. The bracket and filter are directly below the vacuum bag inside the vacuum bag housing. If the machine was run without a bag (or the bag fell off) then this filter is most likely going to be extremely clogged. You can simly remove the filter, and run it under hot water until clean. Make sure the filter is 100% completely dry before putting it back in the vacuum and using it. Running the vacuum with a wet filter will destroy your motor.

Now in terms of the belts. Where as the belts don't directly control the suction of the vacuum cleaner, they certainly facilitate the pick up of dirt and debris on the floor. Many people assume that since the vacuum is not picking up from the floor, then the vacuum doesn't have suction. You can test this by pulling out the attachment hose and feeling for suction, is there suction at the end of the hose? If yes, then the reason the vacuum is not picking up on the floor is because of the belts. If you don't have suction at the end of the hose, then you have a clog, some where or a dirty filter.

The belts actually are what spin the brush, and the brush basically sweeps the carpet, and throws the dirt and debris into the suction port, and when the dirt and debris are near the suction port, the suction then takes over and takes it to the bag.

There are two belts on this model, it's best to replace both of these belts at the same time. If you replace just one, then the other belt will wear out quicker. It's always best to replace these two belts in conjunction.

The two belts that are used on this vacuum are:

Hoover Windtunnel V-Belt Part 38528034

Hoover Windtunnel Flat Belt, Hoover Part 38528035

Once you have the belts, and you're ready to replace them, here's a great video that we shot here at Govacuum.com that shows you exactly how to replace these belts, as well as some basic maintenance on your roller brush;





I really hope that my repair solution was helpful to you in fixing your vacuum cleaner. If you have any further questions about this repair, or any repair, feel free to contact me at chris.jones@govacuum.com, or request a clarification here on Fixya.

The windtunnel vacuum has suction but does not pick up the dirt. I'm puzzled as to what might be the problem. Help!


The problem is that the belts are stretched and worn and slip instead of turn the brush when it is put against the resistance of the carpet. You simply need to replace the belts. Here are the (2) belts you need and the manual with instructions:

Hoover wind tunnel u5755-900. smoke, smell. self-propel


Can you verify the model number? However, based on your posted description, it sounds like the flat belt is either broken or fell off. to access the belts turn it over and remove the bottom plate (4 screws). the Flat belt will connect to the motor shaft in the back and the large black pulley.

Either the inlet down by the brush roll is clogged, or the hose is clogged. Check that out and if you still have a problem, then take it to a warranty repair shop, you have a 1 year warranty on this. Take your sales slip as proof of purchase.
