The wheel fits but is too tight and does not spin freely when the vacuum is dragged across the floor. Now he just leaves scratches on the floor when he drags himself around. It turns by hand but is a little tight when inserted into the base. Now I don't have the option to take it off to get another one and I'm afraid I'll break the base if I try. I really don't want to buy another vacuum cleaner just because of a bad part. sigh
