Having problems with your Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum ?

Bag was not on good, resulted in dust,dirt, dog hair everywhere...have cleaned pretty thoroughly but vacuum does not have any suction. After taking apart did find that the larger wide belt is broke but I think that just affects the self propel...is there a belt tied to suction? HELP!

Greetings from GoVacuum,

\015\012There 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.
\015\012
\015\012Now 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.
\015\012
\015\012The 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.

\015\012There 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.
\015\012
\015\012The two belts that are used on this vacuum are:

I have a Hoover Windtunnel U5472-940. The belt broke so I replaced it. Immediately the next one broke. The belt goes around the brush cylinder and a metal post. I think there is supposed to be something on the metal post to protect the belt but I can't tell from the owner's manual. I also can't find out if this is a part that can be replaced. I've only had the vacuum about a year and a half. Thanks

I'm using (or WAS using) a Eureka ''the boss'' model 8803. The belt broke, no biggie, so I replaced it with a Eureka model U belt, the problem is when I put the new belt on and turn on the vaccuum, the belt breaks again. I am also having trouble getting the brush roller to fit right when the belt is in place. I can't find any sharp edges that would cut the belt,nor can I find where any small bits may have broken. Anyone have a solution for me?


First, make sure you have the right belt, second, i am thinking that you are not lineing the roller up right, it will only fit one way. look at the ends of the roller and the grooves where it slides in, you should be able to see clearly how it goes. ... Vacuums

I have an old Hoover vacuum model # U5035-930. The belt broke and I tried replacing the belt myself. I couldn't stretch the belt to attach it to the motor pully. It was belt # 38525-027 M6. Which I got from the previous owner. I took it to a vacuum repair place and he replaced it with belt # 38528-027 J4. I cannot find this belt anywhere.

I accidently ran over a sock while vacuuming underneath my bed and the belt broke (brush does not rotate now). I've always changed the belts in my vacuum cleaners, but the Healthy Home manual states that I need to bring it into a shop so that a professional repairman can change it. I find this ridiculous and now wish that I never bought it. How do I change the belt myself? PS I have already bought a replacement belt.

Hoover Windtunnel My Hoover Windtunnel is 3 years old. It worked great until yesterday when it lost all suction. I have followed the manual to trouble shoot any possible clogs and could find none.

The Panasonic MC-V7515 has two belts. The local vacuum repair guy says he only has a part number for the drive belt, which is UB-9. How do I find a replacement for the other belt, the one which directly drives the beater bars? By the way, this vacuum has great suction, but otherwise is far inferior to my previous Panasonic vacuums. The cheaper models aren't a good buy--stick with the more expensive models.
