Abstract: A floor cleaning machine constructed as a carriage equipped with a pole and having at least one motor-driven cleaning implement or tool rotating about a vertical axis and for wet cleaning the floor or the like. From a fresh water supply per unit of time there flows-out a regulatable quantity of fresh water to which there is added a cleaning agent, this mixture flowing-out at the region of the cleaning implement or tool. The machine works the floor or the like with the fresh water-cleaning agent mixture by means of the cleaning implement and the thus resulting soiled water is sucked-up from the floor and collected in a separate soiled water container. The fresh water container which supplies the fresh water is formed by part of the machine housing body, whereas the soiled water container is constituted by a separate, portable container which when assuming its working position is enclosed in the machine housing.
