I can assure you, as an allergy sufferer, that vacuuming makes a huge difference in my well-being. Dust and pollen build up and make me miserable. Carpet is tougher to clean, and we're having wood floors installed in part to make cleaning easier.

Maybe it's useful for people with allergies, but I'm not convinced it matters for people with no allergies or severe asthma or anything.
