Cool! Maybe you can figure out what's wrong with my vacuum now. ;-)
 

Sure, Scone! Just get two knives (one sharp, one dull) and go to it. The dull one is to use to open and screws and pry anything that won't give. The sharp one is to cut all of the hair away from the beater bar, it's probably not the problem but it's gross and since you're in there anyway you should get it out.

You may also want to find some long implement to poke into the hoses. I'm always surprised at how much stuff gets stuck.

If that doesn't fix it, then you're going to have to find someone more expert than I am to help you!
 

I hate my vaccum. It's heavy and it doesn't do a good job. It fell apart once when my son pushed it too hard into the wall. I had to fix it. Broke a nail getting the belt back on.
