If the brush does not spin and the motor still works, then the brush belt may be worn down or damaged.
This guide will aid in replacing that belt.

Push the lift away button and pull the handle up to separate the body from the wand section.

Push lift away button on the wand then lift up on the top section to separate.

Tilt the wand shaft backwards for convenient.

Lay the head nozzle piece upside down.

Rotate the three gray taps to the unlock position.

With your fingers, pry and pull the brush cage open.

Remove the 13 screws (circled in yellow) using a phillips screwdriver.
-
Remove the one screw (circled in red) that has a Torx head (might be Phillips head on some models).
-
Remove the horizontal screw (circled in orange) that attaches the gray side panel (necessary to remove the white cap on the roller brush in step 8)
The 13 Philips screws are Torxt 25 screws not philips head screws it’s a Special torx drive tool.
You forgot to explain how to remove the two silver end caps one of them has a philips head screw that has to be removed from the inside,
and it’s hard to find because it’s usually full of lint.
On model NV 752 the torx screw is a T20, not T25. and it is the screw that is in the middle of the unit, not on the end where the red circle is shown above. This is not for the feint of heart. I have now replaced the roller and I am having trouble putting it back together again.
I have replaced roller brushes on other vacuums and this doesn’t have to be this difficult people. I love my Shark but may reconsider buying another based on how difficult it is to replace this roller brush.
I agree with you. The designer knew nothing about "design for assembly" and "design for servicing". I was a design engineer for over 30 years for generators. Those are two important aspects of design. Also, one tries to minimize the number of screws and attempts to make then all the same size. Anyone attempting this for the first time will rate this replacement as difficult. So why is a recessed torx bit required? Obviously, they want service reps to make money.

My NV 752 had all Phillips screws - 15 of them total. One is hidden on the belt side almost under the brush--the only one positioned horizontally--and holds the gray side panel that covers the cap discussed in step 8.
My model number is UV770QCH but it's similar to NV 750 W. I too had a Phillips screw hidden on the belt side under the brush. There was a Phillips screw that ran horizontal to the brush roll cassette that was very difficult to find. As others noted, it was located in a different position from the one pictured in this demo. Also, it was covered in lint and very awkward to reach (glad to have small hands for once). Most other screws required a Torx 20. Four screws (including hidden under brush screw) needed a 2.0 50ml Phillips. Hopefully, my new brush roller lasts a while.

Lift up the top cover now that all of the screws have been removed.
-
-
-
Pry tab out with a flat head screwdriver or any wedge-like tool.
This step is a bit useless as there is a side cover that does not easily come off workout feeling like you're going to break it. I haven't gotten it off to clean my belt because of this. Any suggestions?

where did you get new belts? I bought a set from Amazon for a Shark NV752 and the belts are a bit to large.
