Hepa filter does not rotate

My HEPA filter stopped rotating. I used my shop vac to clean out all around it and rotated it a few times by hand but it still does not completely rotate.

    Mine just stopped also, I cleaned it out and it still doesn't rotate. Just checking the filters doesn't seem to help this issue. How does this filter rotate anyway? Does it have a belt? Or vacumn powered or gear? What would fail on this?

    yes, mine stopped rotating, I've cleaned thebottom filter, and the side one doesn't look dirty, how do I clean it and did it help housecleaner, when they cleaned the filters, and how many filters are there?

    Same problem. My Wind Tunnel 2 is supposed to have a self cleaning hepa filter. Originally, it rotated and also vibrated so the dust would fall into the canister. Looked at other web sites and this is a known big problem. It apparently gets clogged, stops rotating, and thus does not get cleaned. After a while it has a significant loss of suction. Cleaned mine also and suction is better but still not rotating. Can't seem to find any help on how to fix it so it begins to rotate.

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 troubleshooting


Hello! The umbrella tube is a stationary part, it does not rotate. The dirt that enters in the dirt cup spins around the umbrella tube. If no dirt is entering into the dirt cup this can mean there is a blockage either in your hoses and/or your filters. Try these quick trouble shooting steps below.

1. Remove the dirt cup canister from the vacuum. Twist off the dirt cup lid.
2. Remove the primary foam filter. Hold filter under running water until water runs clear. Allow 24 hours to air dry. If the filter is really dirty it may need to be replaced.
3. Slide the Hepa filter out. Tap the filter against the trash can until dirt stops falling. Replace the Hepa filter. (Do not wash)
4. Remove the hose from both ends. Use a broom stick to gently loosen and clear any clogs from hose.
5. Use a wooden spoon or something similar to loosen and remove any clogs from the lower hose. Hope this helps!

I have power on the rotating brush but no vacuum?


First check the filters. If the motor is running properly and the filters clean the most likely problem is a blockage in the tube from behind the brushes pet hair is good at blocking any vac, make sure the vac is disconnected from power then unscrew the assembly under the vac that holds the brushes the drive belt and the tube, once free you should straighten out an old wire coat hanger and prod it through to the inspection flap at the rear of the vac, if this is clear try the same procedure with something more substantial than a coat hanger on the detachable suction hose that you use for getting into corners. If there is no blockage I am sorry that is the limit of my experience.

Brushes stopped rotating


Needs a new drive belt. Find the screws holding the bottom panel onto the floor section of the vac. take out those screws and you should see the motor and the brushes and a broken belt underneath the panel. Check that the brushes spin freely. If not you may have something like hair or string or something jamming the brush. If so cut out the obstruction and then rotate the brushes again and look to see if they rotate evenly, without wobbling because in some vacs if the brushes become jammed and run like that for a while sometimes it wears out the bearings or bushings holding the brush in place and if they are worn you need to replace those as well or when you replace the belt and run the vac it wont take long to break the belt again.

Hepa filter stopped on Hoover Windtunnel 2 Model #U8361-900


This has a simple solution IF you have a air compressor with a high pressure nozzle. Outside the house, first remove the Dust bin completely and lay the unit down with the dust bin area up. now start blowing the nozzle at the hepa filter, Alot of dust will come out. Now start to rotate the filter while blowing the dust out. The filter will move one way easier, When there is no more dust reinstall the dustbin and check the suction and the rotation of the filter.

Hoover Z-400 - Hepa Filter


These filters should be changed at least once a year, they get clogged up and won't clean out. So I would try a new filter and go from there, make sure there are no clogs in the hose and down below where the dirt inlet is.
