How to change a vacuum belt?

can anyone tell me how to change the belt on my bissel powerforce vacuum?How to change a vacuum belt?Ask your hubby or a male friend to help you. Make them show you how to do it. If that is not possible, check with your local vacuum shop. Even if they didn't sell it to you, they might show you how to do it to get your future business. Or call a local handyman. I change my own but I don't have a Bissel, so I can't get you through it, step by step. Sorry!
