My Oreck XL vacuum is not picking up very well. It picks up some things and not others, especially cat hair. The belt and brush look good, I got a new bag in, the bag fills with air when turned on, I checked for clogs... what else can I do? I'm afraid of the price they would charge me to bring it in and look at it, as it is not under warranty anymore. Anyone else had this problem? If so, what was the problem?
