Hoover Wind Tunnel Problem

Good afternoon. While I was running the vaccum a spark came out of the side wher the samll hepa filter is, this was followed by a fouling smelling smoke. At that point the power of the vaccum cleaner dropped dramatically and I unplugged the unit. What the heck was that?

Hi My Hoover wind tunnel cyclonic stopped working when i was using it. I tried different plug even then it doesnt work . What to do??

If the motor stopped running, it most likely did because it was not being cooled, becuause something was stopping up the air flow. If you have cleaned the secondary filter out and it still stops while running, then remove the exhaust filter cartridge and try it then. If it does not stop running now, then the problem is the previous models like this had a foam filter as the exhaust filter, not a heppa cartridge filter. You will not hurt the machine by running it without the heppa cartridge. Cut a foam filter to fit to replace it. I do not think Hoover knows this yet.

I have a customer working on this problem today (Sept 2010) I have repaired machines for 30 years. This filter is meant to just catch the tiny particles from getting back into the air. However, it worked fine on the previous machines with the foam filter here instead of this Heppa cartridge.

Hepa filter does not turn on hoover wind tunnel vacuum model U6630900. It was working (turning) and I cleaned the filter and canister and now it no longer spins when the vacuum is running.

The part you refer to is not the HEPA filter. It's a very common misconception that that part spins - it looks like it when there's dust whirling around it. In fact, it does not spin - there are no visible moving parts.

Filter in Hoover Wind Tunnel Vacuum

Definitely not. Do not use water or any liquids to clean it. Te normal use life is 2-3 years keeping it maintained. You can clean it dry with the dust brush from your vac attachments. place in a plastic bag and tap it some folks even us an air compressor to blow out the impacted dirt. you will only want to use the Hoover brand, other generic brands dont fit as well.

I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. The best way to clean the HEPA filter is to take it outside and use a blower over the trash can and blow off the dust and dirt, or use things like an old paint brush and brush it off, or you can vacuum it off with another canister vacuum or shop vac if you have an extra one. For the best filtration is to replace it, there fore the air flow will catch most of the dust and dirt and then you would have to watch how fast it gets dirty and then do the maintenance.

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. Telephone

My hoover wind tunnel vaccum has a hepa filter that is supposed to be self cleaning but continues to plug up. it is not easy to get to and takes forever to clean it out so the suction is strong again.

do you have the SELF-CLEANING, rotating HEPA filter?

I just fixed my HEPA filter not rotating!!

It involves taking apart the vacuum HEPA area. All screws are the same size. There are a LOT of 'em. Really straightforward putting it back together too.

ok, once you take the HEPA canister area off the vacuum, careful with the wires! Unplug them from the controller board. You open up the HEPA chamber by removing more screws until you see where the motor that turns the filter is mounted on the side. Remove motor from the green chamber. Note where the washer goes. Once the motor is off, you'll see that the center hub that drives the HEPA filter is rounded out. What I did was jam little bits of aluminum from a pop can into the space between the circle and the square to force the walls back to square. I started by folding a little piece of aluminum over and over so it was about three layers thick. Jammed that in. That wasn't quite enough thickness so I shoved another piece with it. If you can find something that is about 4 times the thickness of a pop can aluminum, that'd probably work too. Slight wedge shape on the tip would help. Any sort of tiny shim.

To test your work, just put a couple of holder screws into the HEPA cannister housing, plug in the cover/switch, plug in the HEPA moter. Turn it on for a few seconds to make sure the filter turns. Then you can add more thickness to the hub or put things back together.

Hoover wind tunnel vacuum cleaner shuts off during use

Check the inlet down by the brush roll to make sure it isn't clogged. If not and the hose isn't clogged, then probably the thermo protector (part #28382093) maybe bad. It is mounted near the motor. Could be motor Part #43576188. But I would suspect a clog in the inlet or hose, or the thermo protector has gone bad.
