First, there is no impeller that turns the brush. It is controlled by a turbine assembly. There is the brush with the middle stem (know as the brush block) and the turbine turns the brushes.
Turbines cost $39.00
Brush Block Assembly cost $34.00

Its probably full of dust and lint, and most likely has something wrapped around the motor shaft. Take it apart and inspect in and around the moving parts of the motor, impeller, shaft etc Best way if you are not too handy and poor memory. Either make a video of disassemble or detailed diagrams as you take it apart. It will make your life a lot easier when you re-assemble it!
The air passages through the machine may be plugged, or the impeller (fan) on the motor is slipping on the shaft so that no vacuum is produced. Remove the brush assembly to check the air passage behind it and inspect the brush bearings for collections of thread, string, and hair. Also, inspect the debris collection area for air passage blocking. If there is a filter where the air discharges that might be plugged. Hope some of this helps!
In order to replace the fan you will buy a 2 or three piece lexan fan kit containing the fan a spacer and shaft. You must remove the carpet head and then looking from the back of the machine you will find a series of philips screws on the outer edge of the fan housing facing towards the front, several of which may be partly covered by the motor housing. You will remove the forward facing screws to allow the housing to separate and reveal the fan. If you are lucky there will be a sideways hole through the impeller shaft allowing you to slip a nail through to help twist the saft to unscrew it while holding the fan . The shaft will turn off revealing a threaded motor shaft with spacers which the broken fan will slide off revealing a second spacer at the back . Be sure to replace these spacers in the same order when re-assembling the unit. Secure the shaft hand tight. Post back to advise if you need further help
I have had to use a dremmel tool to cut the plastic around the shaft, you can also something sharp and a hammer to break away the remainer of the fan. There are no threads on the fan so to keep truning it may or may not get it off. Just have to watch and not damage the motor shaft and housing.
