1. A cleaning head for use in a traversing shower system, said cleaning head comprising a plurality of directional liquid nozzles for discharging a liquid onto a working surface, each directional liquid nozzle being provided along a different direction toward the working surface such that no two directions cross one another between the cleaning head and the working surface,
wherein the plurality of directional liquid nozzles includes a first directional liquid nozzle in a machine direction of the working surface, a second directional liquid nozzle opposite the machine direction of the working surface, a third directional liquid nozzle in a first cross-machine direction of the working surface, a fourth directional liquid nozzle in a second cross-machine direction opposite the first cross-machine direction of the working surface, and a fifth directional liquid nozzle normal to the working surface.
