A washing apparatus is compact as well as easy to handle, with which a user can wash down dirt effectively in a short time. Washing liquid supplied from the washing liquid supplying means is made in the form of high-speed jet liquid by a high-speed jet stream spouting means. The high-speed jet liquid is spouted from the aperture of the first cover to wash down dirt by the impact given by the high-speed jet liquid. A washing object is dewatered by gas spouted from the aperture by a blowing means. The high-speed jet stream spouting means is comprised of a rotating object having a plurality of radial shape flow paths extending from a center portion to a circumference of the rotating object, and a liquid supplying portion for supplying washing liquid to a central portion of the radial shape flow paths. A rotating means rotates the rotating object so that washing liquid supplied in the radial shape flow paths is accelerated in the direction of a circumference as well as a radius of the rotating object by rotation. The accelerated washing liquid is spouted from an aperture in the form of high-speed jet liquid.
