Abstract

PURPOSE: An apparatus is provided to accomplish a high effectiveness of removing action with less consumption of water. CONSTITUTION: An apparatus is characterized in that an injection device(200) moving horizontal and vertical direction allows an injection nozzle(201) to simultaneously inject a high pressure water and a compressed air, and an impact force from the water and the compressed air remove or eliminate dirts on a wall or a window of buildings.
