Abstract:
A method and apparatus for cleaning a surface using a high velocity stream or streams of cleaning fluid. The high velocity stream or streams issue from one or more nozzles that are moving at a high velocity relative to the surface to be cleaned. In a preferred embodiment, three nozzles are mounted to a common hub member with two of the nozzles directed at the carpet so that they tend to move the hub member in a first direction about the axis of rotation. The third nozzle is directed at the carpet so that it tends to move the hub member about the axis of rotation in a second direction opposite to the first. The first two nozzles determine the direction of rotation and the third nozzle is then moved relative to the surface so that the velocity imparted to the stream issuing from the third nozzle because of its motion adds to the existing velocity of the stream due to the high pressure alone of the source of the cleaning fluid. This embodiment has been found to work particularly well on carpets.
