A vacuum cleaner has a housing having a bottom portion with wheels. A handle rod with a handle for guiding and pushing the vacuum cleaner across a floor is connected to the housing. A suction blower with a drive motor is positioned in the housing. The housing comprises a brush roller chamber with a rotatably driven brush roller with brush elements positioned therein. The housing has a suction slot through which the brush elements of the brush roller extend. The housing further comprises a receiving chamber positioned between the brush roller chamber and the suction blower with a removable dirt collecting container received therein. 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. A suction channel connects the brush roller chamber to the inlet slot for guiding the suction air stream from the brush roller chamber to the inlet slot. The suction channel tapers in a flow direction of the suction air stream and extends substantially over the length of the brush roller from a periphery of the brush roller upwardly to the inlet slot. The suction channel comprises a guide wall located adjacent to the bottom portion extending upwardly at a slant having a lower edge facing the brush roller chamber and delimiting the suction slot.
