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.

A brush for cleaning a surface, comprising:
- a center core;
- and
- cleaning material, around the center core, comprising nodules,
- wherein a first nodule density of a first region of the cleaning material at a longitudinal center of the brush is different than a second nodule density of a second region of the cleaning material, and
- wherein the nodules at the first region form a helical pattern on the cleaning material.
