Get a Self-Cleaning Broom
People survived centuries without vacuum cleaners and may have had cleaner hardwood floors because of it. Brooms have gotten the job done for generations. We're talking about real brooms, though, made from real broomcorn, not synthetic bristles. A good old-fashioned broom made from broomcorn actually cleans itself as you use it. Soil and dirt particles won't linger between these bristles the way they tend to stick between newfangled synthetic broom bristles.
As an option for cleaning hardwood floors, a real broom is better (and cheaper) than a vacuum cleaner --no dirt bag to change or electricity required -- and more efficient than a synthetic broom. Mother knows best, right? Well, this is what mothers have been using to get dirt off the floor for years.
