AS far as I am aware and I have been in the trade for many years, there are limited spares for the Shark range and no schematics or diagrams due to their policy.
If it fails under warranty, they replace it, they don't attempt to repair them because it is not cost effective.
They are all called 'Navigator' :>D

When switch to carpet, the difference is that the brush roller turns. When it is on hard floors setting it doesn't. Remove the base plate, remove the brush and the belt. There is likely something wrapped around the drive spindle or clutch.
It is possible that the issue is with the motor or an electrical component. If you have access to a multimeter, you could try testing the motor and other electrical components to see if they are working properly. If not, then it may be necessary to replace the motor or another component. You may also want to make sure that all of the wiring connections are secure and not damaged in any way.
You can find diagrams of the wires in a Shark Professional Vacuum Handle online. You can search for the specific make and model of your vacuum to find the diagram. Alternatively, you can contact the manufacturer of your vacuum to request a diagram.
Question edited for clarity and correct name of the vacuum.
Where is the shark vacuum brush bar reset button? You can find the shark brush-bar reset button on the underside of the vacuum.

Shark uses a suction bypass valve on their units. The reason is the vacuum air cools the motor and if there is an obstruction in the line, airflow stops and the valve opens to keep the motor cool. The sound you hear is the bypass being open. You have an obstruction somewhere.
