PCT No. PCT/JP97/00285 Sec. 371 Date Dec. 17, 1998 Sec. 102(e) Date Dec. 17, 1998 PCT Filed Feb. 6, 1997 PCT Pub. No. WO97/28731 PCT Pub. Date Aug. 14, 1997An automatic floor washing apparatus that washes and polishes the floor at one time with the provision of through holes or apertures for the nonwoven disc pad fixed to a pad base, which is driven by means of a motor at high speeds. With the structure thus arranged, it is possible to reduce the working steps significantly unlike the conventional cleaning operation where the floor washing and polishing is carried out by separate machines, a floor washing apparatus and a high-speed polisher, individually.
