An apparatus for cleaning a wafer oriented vertically is provided. The apparatus includes a first brush and a second brush located horizontally from the first brush. During use, a wafer is oriented vertically the first and second brushes. The brushes are brought into contact with the wafer and rotated thereby engaging the wafer with rollers. By rotating the rollers, the wafer is also rotated. Liquid is sprayed towards the brushes and wafer. By orienting the wafer vertically, liquid and particulates contained therein readily fall from the water due to gravity. This is particularly advantageous when cleaning larger diameter wafers in which particulates must be removed from a larger wafer surface area.
