A wall cleaner structure hung by a cable (L, fig 3) and adapted to automatically wash a wall surface comprises a frame 10 connected to the cable (L, fig 3), a cleaning device 20 and a collection device (50, fig 3) for collecting the used wash liquid. The cleaning device includes at least one spraying member 21 for spraying liquid onto the wall surface, at least one cleaning member 22 lying horizontally above or beneath the spraying member 21, a collector 23 for collecting soiled cleaning liquid, three barrier members 24 disposed at a periphery of the clearing device for sealing the cleaning device against the wall and a suction device 30. The suction device includes first 31, second 32, third 33 and fourth 34 suction members and a suction fan 35 for drawing wash liquid from the wall surface through the suction members 31-34. The suction fan 35 includes a spray vent (351, fig 2) for disposing of some of the used wash liquid. The collection device 50 is positioned beneath the cleaning device for collecting the remaining waste liquid. The wall cleaner structure washes the wall surface in an automated manner, prevents accidents, and prevents waste liquid from flowing downward across the wall surface or even falling to the ground. |
