You should vacuum your carpets at least once a week, even if they don't look dirty. Carpets work as a filter for the dust in your home. Dust and allergens are trapped by the fibers and it helps keep your air cleaner. Vacuuming your carpets often gives them the best chance of removing the most dust possible. Sweep or vacuum your wood floors weekly as well. The dirt that gets tracked into your home works like sandpaper on the surface of the flooring, quickly dulling its shine and damaging the floors.
