PROBLEM TO BE SOLVED: To provide a liquid suction device which does not leave any liquid traces such as droplets or streaks on the surface to be cleaned.SOLUTION: A liquid suction device (1) has a suction head (2) with a suction gap (4) delimited by two lips (3), a dirty liquid tank (5), and a suction fan (6). The suction gap (4), the dirty liquid tank (5), and the suction fan (6) are connected to one another by means of a suction duct (7) in such a way that liquid can be sucked from a surface to be cleaned into the dirty liquid tank (5) via the suction gap (4). One end of an air duct (8) is connected to the positive pressure side of one fan or to the positive pressure side opposite the suction duct (7) in the suction fan (6) and the other end of the air duct (8) is connected to the suction gap (4), so that blast air generated by the fan or the suction fan (6) can be conveyed into the suction gap (4).SELECTED DRAWING: Figure 1 |
