Motor runs vacuum has suction on attachment but brushes won't Rotate
This problem is most often caused by a broken brush roller belt. Sometimes, although very rarely, there is a separate motor which turns the brush, or there may be something that is causing brush roller to bind so that a belt does not last long. I don't know what your situation is but I'll give it my best shot. Lets just assume the most common problem (97% of the time) and that it is a broken belt,
FIRST: UNPLUG THE VACUUM CLEANER. Write down the model number of the machine so that you make have it with you when you purchase a new belt.
Set up an area to work and lay down newspapers to do this job as it can be messy. Or, of course, if you do it on the carpet, you can vacuum it up when your finished
Normally to remove the brush roller and install a new belt most vacuums will have some way to gain access. Either there are:
a) Screws on the top of the roller sections that if you remove them you can tip the cover up so that you can remove it. Sometimes there are cosmetic caps over where the screws are. or
b) Screws on the bottom of the roller section so that you can remove them, then a cover, and then the brush roller itself.
When you have the roller exposed, remove it carefully and take note to observe the parts and how they are oriented. This will help with the reassembly process. Often the brush roller is a simple one piece unit, but it pays to keep track of your work.
1 Remove the broken belt.
2 Remove the brush roller.
3 If there are any carpet strands wrapped around the roller, remove or unwind them. If there is material that is causing the roller to bind which is caught in the ends of the roller, of course, remove them as well.
4 Reinstall the roller with the belt loosely wrapped around it so that the other end of it can be put around the motor shaft that turns it. This step may be harder than it looks and you may need a lot of strength to wrap the belt around that shaft. It depends on the design of the unit. Sometimes it is alternately easier to put the belt around the shaft first and then put the roller into position.
5 Once the roller and belt are in their final positions, Re-assemble.
6 Before plugging the vacuum cleaner in, Check to see that the Roller will turn without binding.
You will need to use some force because you are turning the roller itself and the motor via the belt. So it does not need to turn easily but it should not be stuck. If it is stuck, for any reason, when you turn the vacuum cleaner on you will burn up the new belt with plenty of smoke
to make things exciting and stink up the house.
7 If the belt is not binding then plug the cleaner in and test it.
All should be well,
Hope this helps,
