<p>A water holding device for a window washer has a first water tank (10) for the reception of a window washing tool (18), and a second water tank (26) in communication with the first water tank at its lower end via a slot (32), for the relief of pressure caused in the first water tank by rapid insertion of a working tool (18) into the first water tank, the water holding device being of progressively decreasing cross-section in a downwards direction in order to minimise the volume of water required in the first water tank, and thus minimise the weight to be carried by the user. <IMAGE></p> |
