A brush roller is located above the vacuum opening in the casing in a brush chamber so that the bristles protrude into the vacuum opening. A flow duct connects the brush chamber to the connection for the vacuum air flow. A turbine chamber in the flow duct is fitted with an air turbine and the brush roller can be rotated by the air turbine. A wet vacuum duct parallel to the brush chamber and the flow duct connects the wet vacuum opening located on the level of the base of the casing to the connection and a switchable flow blocking device is fitted in the wet vacuum duct and in the duct.
