I have an older Hoover Encore Supreme vacuum with a broken belt. I have located the belt I need but I can’t figure out how to get the bottom off to replace it. I’m handy at doing simple repairs such as this but I don’t see any screws or clips once I take the cover off the bottom, I’ve looked very closely. It’s a great vac and don’t want to replace it so I thought I’d give at home repair a try before I take it to the repair shop. Can someone tell me of a website that can give me directions on taking this specific model apart?
