Claim 0:
1. A cleaner, comprising a dust-removing head,
wherein the dust-removing head has a work-corresponding face of convex, concave, or convex-concave three-dimensional configuration,
wherein the dust-removing head jets air to a cleaned face of a work having the cleaned face of a three-dimensional configuration of concave, convex, or concave-convex,
wherein the configuration of the work-corresponding face of the dust-removing head corresponds to and is separated from, by a proximate distance, the configuration of the cleaned face of the work, and
wherein the work-corresponding face of the dust-removing head comprises a plurality of different surface areas with respective air jetting holes of differing diameter sizes, and
wherein the different surface areas are located at different distances from the longitudinal axis along which the dust-removing head extends, each of the different surface areas having air jetting holes with diameters that are different from diameters of other air jetting holes of another one of the different surface areas.
