  • Patent number: 6088871
    Abstract: Cleaning equipment according to this invention comprises a pile layer provided on a mount base portion composed of a hard plate body with a handle, a blockish grip portion having flexibility and elasticity, an engaged layer for engagement with a polisher, or the like. The pile layer comprises a multiplicity of monofilaments which are planted one by one while kept upright. Also, according to another concept of the invention, an end face of a free end portion of the pile layer is in the form of a substantially isogonal trapezoid or the like. With such arrangement, it is possible to easily, positively and very cleanly clean a surface being cleaned irrespective of roughness and degree of soiling of the surface being cleaned. Further, according to another concept, the surface being cleaned can be similarly cleaned even when the surface has corner portions and, therefor, obstacles are constituted around the surface.
