Abstract: A vacuum cleaning tool has a housing with a partition dividing an interior of the housing into a brush chamber and a turbine chamber. A vacuum connector is connected to the housing remote from the brush chamber. A working roller is arranged in the brush chamber. An air turbine is arranged in the turbine chamber and drives in rotation the working roller. A vacuum air flow enters the brush chamber, flows from the brush chamber through an intake window into the turbine chamber, flows within the turbine chamber through the air turbine, and exits from the turbine chamber to the vacuum connector. The turbine chamber has a chamber bottom with a ramp ascending toward the outlet window in the area where the vacuum airflow exits from the turbine chamber. The ramp is through-shaped and has a groove extending in the flow direction of the vacuum airflow.

Abstract: A vacuum cleaning tool has a housing with a brush chamber and a turbine chamber. A vacuum connector is connected to the housing remote from the brush chamber and has an outlet window. A working roller is arranged in the brush chamber and driven by an air turbine in the turbine chamber. The air turbine has an annular vane arrangement with vanes. The vacuum airflow enters the brush chamber via a suction slot, flows from the brush chamber into the turbine chamber, passes through the air turbine, and exits through the outlet window of the vacuum connector. In the flow direction of the vacuum airflow the outlet window is higher than the intake window. A connecting line between central areas of the intake and outlet windows intersects the air turbine as a secant to define a circle segment in which four to six of the vanes of the annular vane arrangement are located.

Abstract: A vacuum cleaning tool has a housing with a brush chamber and a turbine chamber. A vacuum connector is connected to the housing remote from the brush chamber. A brush roller is arranged in the brush chamber and an air turbine is arranged in the turbine chamber for driving the brush roller. A vacuum airflow enters the brush chamber via a suction slot, flows from the brush chamber into the turbine chamber, flows within the turbine chamber through the air turbine, and exits from the turbine chamber into the vacuum connector.

Abstract: A vacuum cleaning tool having a housing that includes a connector for a vacuum hose of a vacuum cleaning apparatus is provided. Disposed in a brush chamber of the housing is a brush roller, the bristles of which project through a vacuum slot formed in the base plate of the housing. The brush roller is driven via a belt drive by an air turbine, which is provided in a turbine chamber of the housing.

In order when the vacuum cleaning tool is raised from the floor to reduce the drive power, the guide member is pivotably mounted in the housing of the tool. In a first operating pivot position the suction air stream is directed essentially tangentially against the air turbine to achieve a high drive power. In a second, non-operative pivot position the suction air stream is directed essentially radially against the turbine to achieve a low no-load speed.

The brush chamber communicates via a connecting channel with a dirt collecting chamber. To ensure a reliable sweeping-up of dirt and a simple emptying of the apparatus, the dirt collecting chamber directly adjoins the main housing and is formed in an independent chamber housing that is separable from the main housing. The chamber housing has a sweeping ramp that leads to the dirt collecting chamber and a front edge that is remote from the dirt collecting chamber, extends transverse to the direction of work, and is disposed at approximately the path of the bristles of the brush roller.

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.
