Abstract
Provided is a disclosure for a brush for cleaning a surface, where the brush comprises a center core and cleaning material around the center core. Modules are found on the cleaning material, where nodule density on the cleaning material varies. Accordingly, a first nodule density of a first region of the cleaning material is different than a second nodule density of a second region of the cleaning material.
