A squeegee device including a mount carried pivotally from a handle for mounting a squeegee blade in a normal position for sweeping the majority of the distance across a window pane recessed in a window opening defined by abutment walls of, for instance, a high rise building. The mount is biased to the normal position by a bias spring and a kicker arm is carried on such mount. The kicker arm is constructed to, when the apparatus approaches completion of the stroke, engage the abutment wall forming the window opening to orbit the mount and consequently such blade through an arc relative to the handle thereby accelerating movement of such wiper blade to complete the wiping stroke.
