You generally dont clean hepa filters .. you replace them .. temporarily you can tap them on the driveway to loosen up the big particles .. but the filter normally is replaced ... there are some filters that are washable in hot soapy water .. but hepa filters are normally not ..

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.

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.

Check with the manufacturer. I have always had good response from Hoover.

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.

The HEPA filter is not a cleanable item. The pre-motor filter is the washable one.
