The invention relates to a mobile floor cleaning device (10) comprising at least one cleaning tool (22, 23), a cleaning liquid tank (36), a dirt liquid tank (26) and a suction unit (32). In order to further develop the floor cleaning device (10) such that it has a reduced noise emission, a first recess (30) is formed into the tank wall of the cleaning liquid tank (36) or the dirt liquid tank (26), the suction unit (32) being arranged in said recess which is covered by a first cover element (51). According to the invention, the tank wall and/or the first cover element (51) form at least one air guide channel (76, 79, 83) extending from the first recess (30) to an opening (77, 80, 84). |
