Can anyone recommend a very lightweight vaccum that picks up well? I have a heavy one that does a good job but I can't carry it up and down stairs every time I need to use it. I need something for lighter soiled carpet but that still picks up well because it's mostly pieces of dried leaves being tracked in and stuff like that- fuzz from laundry, etc, you get the idea. I wish they made one that could break down enough to also be used as a handheld battery operated vacuum for the car but I guess that's asking too much. LOL!
