Review on 14-Piece Pink CALBEAU Microfiber Feather Duster Set with 100-Inch Extension Pole - Bendable, Washable, and Perfect for Cleaning High Ceiling, Fan, Blinds, Windows, Furniture, and Cars! Great Cleaning Tools Gift for Women! by Kendra Johnson

I have this for places where I need stairs. (Dust on bookshelves, cobwebs in corners, etc.) An extension cord makes it easier to reach higher places without having to climb the stairs. The picture shows how easily I can reach the highest corner of the stairs between the first and second floors. The extension can be switched to fit different heads and is light enough to be carried with just one hand.
