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.

[ What is claimed is:] [1.] A cleaning brush comprising a mounting base and a pile layer provided on at least one surface of the mounting base,the shape of a surface on a free-end side of the pile layer being characterized by:(1) having a long-side edge substantially straightly extending over the whole length of the pile layer;(2) having an acutely projecting portion lying near each end of the long-side edge; and(3) providing a free-space in which neither the mounting base nor the pile layer is, and which is bounded by both a first imaginary line passing through each distal end of and extending perpendicular to the long-side edge, and a second imaginary line corresponding to a straight envelope line of an intermediate side edge and passing though each distal end of the long-side edge and forming an acute angle of between 4-40 degrees with the first imaginary line;the mounting base being made of hard material and shaped into a substantially plate-like form, the one surface of the mounting base having a planting portion, an opposite surface of the mounting base having a handle portion, and the planting portion having a backing layer provided on the one surface of the mounting base, and the pile layer provided on the backing layer; andthe pile layer being constituted of a multiplicity of monofilaments planted on the backing layer one by one in a substantially upright state and in density of 1,000-50,000 monofilaments per cm.sup.2 so that the thickness of the pile layer is 0.8-7.8 mm, and the fineness and the elastic modulus (when tested by ASTM, D638-52T) of the monofilament are 5-50 denier and 13,000-38,000 kg/cm.sup.2, respectively.
