Abstract: An electrostatic cleaning device includes: a flying portion having a body, at least one power source, at least one extension extending from the body, defining a hollow interior, at least one propeller configured to generate lift for the electrostatic cleaning device located at an end of the at least one extension, and at least one electrical connection extending through the hollow interior, connecting the power source to the propeller. An associated spray system includes a tank mounted to the flying portion and configured to store a cleaning spray, at least one spray mechanism in fluid communication with the tank to discharge the cleaning spray, and at least one electrostatic generating unit configured to apply a voltage across a spray path of the cleaning spray, so that the spray is electrostatically charged. At least a portion of the at least one extension is coated or shielded by nanotube particles.
