Unger makes several cleaning products especially to help the dust. This flat duster is 18 inches long and useful for flat narrow surfaces such as, bookcases or under something. The pivoting head adjusts and locks in place for dusting at different angles. The microfiber dusting sleeve can be removed and washed or replaced. It also attaches to the Unger telescopic pole for reaching higher areas. I do recommend but wish it was longer so it would reach all the way under appliances.
