ABSTRACT:
The window washing tool is a tool for washing windows located high above ground without requiring the use of ladders or scaffolding. The window washing tool has an extension handle which serves as both a reach extension device allowing reaching high windows from the ground, and for supplying water and cleaning solution to a washing head. The washing head holds the implements used to clean the window. The extension handle has a plurality of sections, which are connected together to provide the required length. The extension handle is hollow and conducts water supplied at pressure to the lower end of the extension handle to the washing head at the top of the extension handle. A lower section of the extension handle includes a shutoff valve for controlling the flow of water to the washing head, and a reservoir for introducing cleaning solution into the flow of water.
