PURPOSE: An all-purpose window cleaner is provided to economize in washing water and to prevent dirty water from flowing down a window by not spraying water directly as well as to clean the outside of the window in an indoor space. CONSTITUTION: Plural small water sprayers(3) are arranged in a row on an upper support(2) of a window brush. Pressurized air flows into an inner passage connected with a removable air press(4) forcibly to spray water. A direction changer(5) moves the brush freely and a length control connector(6) adjusts height of the brush. An L-shaped directional handle(8) helps a user clean the outside of a window in an indoor space. Plural screws are useful to replace the connector(6) and handles(7,8). Therefore, the user cleans the window by adjusting the direction and length of the brush freely.
