-	If it is set too high (like for a deep carpet) on a low pile carpet, or on a smooth floor, you will hear much more noise, both from the brush roll, and from the airflow of the vacuum.

	*Is the brush roll loaded with hair, string and other debris?* The vacuum will make more noise, and this can ultimately stop the brush roll from turning, and cause broken belts.

	*Is the brush roll damaged?* A damaged brush roll can also lead to noisy operation. Check to see that none of the brushes on the roll are coming loose and possibly striking the brush roll housing. You can do this while you have the brush roll out to clean it.

-	*Are the brush roll bearings worn out?* Worn out bearings on the brush roll will make a vacuum much noisier. This is a good time to check them after cleaning and inspecting the brush roll.

	** You can flip it end for end and repeat for a more complete check.
