Kind Code:

PURPOSE: To provide a lift a wall surface which can keep a gap between the wall surface and a cage constant by holding the cage horizontally without slanting the same and vertically moving without left and right lateral deviation.

CONSTITUTION: A cage 10 hung with a wire 40 for cleaning a wall surface is moved vertically while facing the wall surface. A fixed sucker 54 spans vertically a window glass to be attracted to the wall surface so that the cage is held horizontally and a gap between the cage and well surface is held constant. Then, a window wiping operation is mechanically carried out by a scraper 36. When the cage is shifted to the window wiping operation at the lower story, a rod-less cylinder 66 moves a guides sucker 100 to the lower portion of the cage 10 so that the sucker 100 is attracted to the wall surface. Next, the attracted condition of the fixed sucker 54 is released. Then, the wire 40 banging the cage 10 is unwound down and the cage 10 is lowered along a guide rail 62 while being guided by the guide sucker 100. These step are repeated to wipe windows.
