The conventional electric floor polishing machine has the following problems.

(1) Cleaning pad 2 in the case of dry wipe or water wipe
Since the area of the floor is limited, several spare cleaning pads 2 must be prepared and replaced when the floor surface is extremely dirty, and the replacement work is troublesome, and the cleaning pad 2 cannot be used after use.
It was troublesome to wash and dry and store it, and to secure a storage place.

(2) In the case of waxing, there is the trouble that the wax must be sprinkled on the floor surface. Also, the point of waxing is to apply the wax uniformly and quickly, but it is to apply it as evenly as possible in the previous step of waxing,
Otherwise, there is a problem that it takes time to apply it uniformly and wax coating unevenness is likely to occur.

(3) Since this equipment does not have a function of capturing and collecting dust, it is of course necessary to remove large dust with a vacuum cleaner or the like before polishing the floor. However, if the dust such as dust is not removed to some extent, the cleaning pad 2 becomes dirty quickly, so the cleaning pad 2 must be replaced sooner. The dust adhering to the pad 2 was sometimes applied to the floor together with the wax.

The present invention solves the above-mentioned problems and does not require frequent replacement of the cleaning pad and enables continuous cleaning work with a clean cleaning cloth that has not been used, and electric floor polishing that allows easy processing of the cleaning cloth after cleaning. The purpose is to provide a machine.
