I think the old wheels got lost when we moved. I know they cracked and didn't hold up in vacuum (broken side pin). So, being in stay-at-home mode during this "challenging time (as the ad says),” I figured I'd revitalize that vacuum. The wheels arrived quickly and you simply insert the side pins into the bracket and snap into place. Easy. The install took what, 5 seconds? Now I have a working vacuum again and don't have to lug it across the floor. So worth the money; Why throw away a great vacuum cleaner when it's so easy to fix? We all need to stop throwing things away when they break and fix things. I think it's fun to work on things!
