The filter for the U5753 does not rotate on it's own. There is a knob on the lid of the dirt canister to rotate before you empty the container, but it does not rotate automatically. If the filter is getting dirty quickly, it could be a result of very fine dirt going through the pre-filter screen and blocking the filter. You should also check the filter UNDER the dirt container for blockage and also the exhaust filter on the side. These are both washable and must be bone dry before re-installing
The main filter cartridge is a long cylindrical style and is coated with a teflon material so that all you should have to do is tap the filter lightly to dislodge any dirt. You can wash the filter by running warm water over it and using a SOFT brush to clean the surface. This filter must be BONE DRY..... before re-installing.
By the way, the lifetime filter is not lifetime. It should be replaced every two years, under normal use.

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.
1. Remove the 4 screws holding the bottom plate.
2. remove roller and old belt
3. install new belt on motor spindle first and then on roller.
4. pull roller, stretching belt, set into roller cavity.
5. turn roller by hand to center belt.
6. reinstall bottom plate.& screws
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.
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.
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.
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.
