Abstract

A vacuum attachment comprises a base having an upper face and a lower face, and an outer surface and an inner surface. The inner surface defines a first flow passage between the upper face and the lower face. The lower face provides a smooth contact surface. A single orifice extends through the base from the outer surface to the inner surface. The orifice is spaced apart from the lower face.
