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. This soiled water container is connected via a seal to the suction compartment of a suction blower and is protected from over filling by means of an automatically operating level limiting device. Further, means are provided to ensure that the water of the mixture of air and soiled water which enters the machine does not contact the suction blower and also prevent the splashing water of the soiled water container which may splash around during movement of the machine from entering the suction blower.

A floor cleaning machine constructed as a carriage equipped with a guide pole, at least one motor-driven cleaning tool for wet cleaning the floor and rotating about a substantially vertical axis, a regulatable quantity of fresh water admixed with a cleaning agent being delivered per unit of time from a fresh water supply to the region of the cleaning tool, the cleaning tool processing the delivered fresh water admixed with the cleaning agent at the floor and the resultant soiled water being sucked-up from the floor and collected in a separate soiled water container, the improvement comprising: a machine housing, a suction blower mounted on said housing, a fresh water container formed by part of the machine housing, the soiled water container comprising a loose portable container which is enclosed in the floor cleaning machine when it assumes a working position within the floor cleaning machine, a suction compartment having an air entrance aperture, the soiled water container being connected via a seal with said suction compartment, said seal comprising a marginal edge formed on said soiled water container, the edge of said suction compartment aperture, and a detachable intermediate element engaging both said suction chamber aperture edge and said marginal edge, an automatically-operating level limiting device for preventing the soiled water container from over filling, a downwardly inclined collar extending within said suction chamber, the incoming air and soiled water sucked-up from the floor by said suction blower being directed against said inclined collar, the soiled water flowing downwardly on the surface of said collar and into the said soiled water container, and a plurality of flow direction changing members mounted above said suction compartment for changing the direction of travel of the air and entrained water particles therein to thereby prevent said entrained water particles from entering said suction blower. The floor cleaning machine as defined in claim 1, wherein the machine housing includes a compartment in which there is accommodated the soiled water container when it assumes its work position, a cover for selectively closing and exposing said machine housing compartment, means for mounting said cover to be pivotable towards the outside of said housing about a substantially horizontal axis, said pivotable cover in its pivoted-out position forming a platform which is located at least approximately at the height of the floor of the machine housing compartment, the soiled water container being removable from the machine housing compartment via the said platform and again being introducable into the machine housing compartment through the agency of said platform.
