In the state of being superposed on the inside of the blade, a thin film plate with a length of which the lower end is in contact with the floor is installed in parallel.

(2) A plurality of notches are formed in the film plates arranged side by side inside the blade in a substantially comb-like shape at intervals in the lateral direction.

(3) The length of the film plates arranged side by side inside the blade with respect to the floor surface is formed to be slightly shorter than the length of the blade.

The means described in (1), (2), and (3) above operate as follows.

According to the means described in the above (1), since the elastic film plates are arranged inside the blade, the film scrapes dust and the like during normal cleaning, so that the blade and the floor surface are not in contact with each other. Prevents dust and the like from being caught as much as possible, and if it should be caught, by retracting the floor washer (squeegee), the blade is bent in the opposite direction (forward direction) and caught. It pushes out dust, etc., and at the same time flexes the waisted film plate and pulls out dust, etc. to fly it away, so dust can be sucked by the blower's suction force, and the floor cleaning machine retreats. Continuing with, the blade and the film plate are reversed in the opposite direction, the film plate is completely separated from the floor surface and the tip of the film is vibrated under the influence of suction air, so dust etc. may temporarily be present at the tip of the film plate. With Even if you are, making it possible to suction reliably screened off this.

According to the means described in the above (2), the elastic film plates arranged side by side inside the blade are bent back and forth and sucked air by a plurality of notches formed at intervals in a substantially comb-like shape. Because the vibration due to each unit can be easily and reliably performed with a small amount of force, in response to the forward and backward operation of the floor washer, the trapped dust is immediately pulled out and skipped. It is possible to reliably remove the trapped state of dust or the like by shaking it or shaking it.

According to the means described in the above (3), since the film plates arranged side by side inside are formed to be slightly shorter than the blades, the blades scrape the dirty water during the forward operation of the floor cleaning machine. On the other hand, the film plate can scrape away dust, etc., and during backward operation, the film plate bends forward and forwards ahead of the blade, reliably pulling out dust caught in the lower end of the blade and throwing out cissing. Make it possible to do.

As described above, the above (1) to (1)
The technical problem described above can be solved by the means described in (3), and the problem of the conventional technology can be solved.
