A rotating suction wand for a cooler box screen including a hollow body for attaching to a suction hose. A first slot and at least a second slot are formed in the hollow body in fluid communication with an interior of the hollow body for facingly engaging a screen. The construction and arrangement of the slots redistributes suction force along the length of the wand in such a way as to compensate for differences in angular rotational speed of the wand at varying radial distances from the center of the wand as well as to overcome suction force reduction which normally occurs from the center to the ends of the wand. Consequently, debris is more effectively removed from the screen from the central regions of the wand to radially distal regions thereof.

Systems and methods for self-cleaning a surface of an object where an electrodynamic shield is mounted to a surface of the object. The electrodynamic shield includes one or more sets of electrodes atop a substrate, at least one or more sets of electrodes being covered in a protective film. A coating is applied to the top surface of the protection film. A signal pulse generator is connected to the one or more sets of electrodes. The signal pulse generator generates a pulse signal that causes the one or more sets of electrodes to generate an electric field. The pulse signal comprises a plurality of different pulse signals which have phase differences between consecutive signals, and the electric field causes a particle atop the coating to experience an electrostatic force and be repelled away from the coating. These pulse signals (including shapes, amplitudes, shifts, and frequencies) can be tuned to increase efficiency of removal depending on dust type and relative humidity.

The invention consists in a device for cleaning a sensor of a motor vehicle.

A piston (2) is able to slide in a circular hollow body (1) having a longitudinal axis (XX) and carrying at a first end a single nozzle (4) for distributing one or more fluids, said piston being hollow to enable the routing to the nozzle of at least one first fluid.

The hollow piston is rendered mobile, between a rest position and a working position, by the effect of a second fluid to take up a working position in which the nozzle is deployed.
