The dirt collecting container has sidewalls wherein a first one of the sidewalls faces the brush roller chamber and has an inlet slot extending substantially over the length of the brush roller chamber for allowing passage of a suction air stream entering the suction slot into the dirt collecting container.

Abstract: A vacuum cleaning tool comprising a housing having a base that is provided with at least one intake opening over which is provided a brush chamber in which is disposed a brush roller having bristles that project into the intake opening. A flow channel connects the brush chamber to a connector that can communicate with a vacuum line of a vacuum cleaning unit. A turbine chamber is disposed in the flow channel and accommodates an air turbine that can rotatably drive the brush roller. The housing also has a wet intake opening that is disposed approximately in the plane of the base of the housing. Parallel to the brush chamber and the flow channel, the housing has a wet intake channel that connects the wet intake opening to the connector. Respective controllable flow blocking devices are disposed in the wet intake channel and in the flow channel.

Abstract: A vacuum cleaner includes a receptacle and a cover, for closing the receptacle, having a radially open chute. A drive motor is connected within the cover.

Abstract: Known suction devices for liquids are provided with a motor-driven suction fan, that introduces an air/liquid flow via a suction nozzle into a liquid receptacle in which the liquid is separated and collected. In order to avoid introduction of liquid into the motor-driven suction fan a device for monitoring the level of liquid in the receptacle is provided which, when a maximum filling level is reached, activates an emptying display. In order to achieve an exact determination of the filling level of the receptacle; it is suggested to provide the monitoring device in the form of a light barrier.
