  • Patent number: 7937801
    Abstract: A floor cleaning appliance has a brush head in which a brush roller is rotatably mounted and which has at least one suction nozzle which is disposed next to the brush roller. Further, the floor cleaning appliance has a shank which is mounted on the brush head in a pivotable manner and on which a suction unit is disposed, as is a cleaning liquid container for cleaning liquid which can be applied to the floor surface to be cleaned, and a dirty liquid container for accommodating dirty liquid which is sucked up from the floor surface by means of the suction unit, the cleaning liquid container and the dirty liquid container together forming a container assembly which is adapted to be releasably connected to the shank. In order to develop the floor cleaning appliance in such a way that it is easier to handle, it is proposed that the cleaning liquid container is adapted to be releasably connected to the dirty liquid container.
