The rattan Carpet Beater, produced by the Redecker company in Germany (makers of fine brushes and housewares since 1936), is best "used in conjunction with vacuuming for a most effective rug cleaning solution. Beat the carpet from the backside to expel dust and dirt and to protect the exposed surface." No carpets?  I saw this at DWR Tools for Living in New York yesterday and thought it made a great piece of wall art. $20 at Design Within Reach.
