PURPOSE: A veranda window cleaner is provided to install the cleaner from an upper portion to a lower portion at a chassis post of the window and cleanse the window with water by moving a brush to right and left sides of a supporter. CONSTITUTION: A veranda window cleaner is installed at a chassis frame at the side of a window(4) and is connected with a water supplier. A brush(5) cleanses the window(4) by moving a supporter(6) to right and left with alternatively pulling two of laces(9). When the cleansing is completed, the cleaner is installed again by moving the cleaner from an upper portion to a lower portion in an interval of the thickness of the brush. The cleaner easily moves between rails because the thickness of the cleaner is less than a gap between a veranda rail and window chassis(3).
