Abstract: A method of manufacture includes processing an object in a chamber and subsequently generating an electrical force of attraction to float contaminants off of a region adjacent the processed object before the object is unloaded from the chamber. The object may be processed with the use of plasma. The plasma is produced by introducing a first gas into the chamber and applying a source power to the first gas. The plasma is extinguished after the object is processed with the use of the plasma. Then, a second gas is introduced into the chamber and a source power is applied to the second gas to generate the electrical force of attraction. At this time, the parameters are controlled so that particle contaminants are readily removed without any influence on the object. Also, the same electrode can be used to apply source power to both the first and second gas. Thus, the operation of removing the particle contaminants is relatively simple.

Abstract: A swimming pool cleaner discharges water jets under the cleaner body, directed toward its center from its sides, to agitate and lift debris toward one or more vacuum intake openings, to greatly enhance the cleaning ability of the cleaner. The suspended dirt and debris become semi-buoyant under the force of the jetted water which is preferably moving in the same direction as the cleaner, so that the relative speed between the cleaner and the suspended dirt and debris is reduced, thereby enabling the cleaner to move at a relatively faster rate and still clean with equivalent or even greater efficiency than a pool cleaner that is not equipped with directional cleaning water jets. In addition, displaced front and back orientations of the intake ports allow for longer time for any dirt and debris to be picked up.
