Cleaning dirt with dirty vacuum

The brush on the Bissell 3 in 1 Turbo vacuum stick cannot be removed from cleaning. Even after removing the screws, the backing doesn't come off the vacuum so that you can remove the brush. You are required to pick all the debris off the brush while it's in the machine which is difficult. And since you cannot take the vacuum cleaner apart, you are virtually unable to clean the dirt and grime from the compartment where the brush is located.

You are forced to clean with a dirty vacuum.
