In my opinion, it's a totally different approach that accomplishes roughly the same thing. I agree that manually vacuuming is better, but you probably don't have the wherewithal to do it daily. The average amount of dirt on your floors after manually cleaning once or twice a week is probably the same, or more, as what a Roomba leaves on the floors after cleaning daily. That's really where it shines: relentlessly cleaning every day.
