Here's how to stretch the belt. Take a large screwdriver, e.g., #2, and stick it through the belt, but only barely, so the belt is nearly at the end of the screwdriver. Have someone hold the vacuum cleaner in place while you stretch the belt, with both hands on the screwdriver. This way, it just takes a little effort and a few seconds to stretch the belt farther than you ever believed possible.
