Abstract
A water holding device for a window washer as a first water tank for the reception of a window washing tool, and has a second water tank in communication with the first water tank at its lower end for the relief of pressure caused in the first water tank by rapid insertion of a working tool into the first water tank, the water holding device being of progressively decreasing cross-section in a downwards direction in order to minimize the volume of water required in the first water tank, and thus minimize the weight to be carried by the user.
