The Cloud Duster is the original long-strand microfiber dust mop. The Cloud Duster uses unique microfibers that have millions of long-strand hooks and channels resulting in increased surface area to attract and hold more dust than disposable sheets and standard cotton dust mops. And unlike cotton dust mops, there's absolutely no need for dust treatments or chemicals of any kind on the Cloud Duster. With its swiveling head, the Cloud Duster is great for cleaning hard-to-reach places.
