An active electroadhesive cleaning device or system includes electrode(s) that produce electroadhesive forces from an input voltage to adhere dust or other foreign objects against an interactive surface, from which the foreign objects are removed when the forces are controllably altered. User inputs control the input voltage and/or designate the size of foreign objects to be cleaned. An active power source provides the input voltage, and the interactive surface can be a continuous track across one or more rollers to move the device across a dirty foreign surface. Electrodes can be arranged in an interdigitated pattern having differing pitches that can be actuated selectively to clean foreign objects of different sizes. Sensors can detect the amount of foreign particles adhered to the interactive surface, and reversed polarity pulses can help repel items away from the interactive surface in a timely and controlled manner.

Active electroadhesive cleaning

An electrostatic device or system includes electrode(s) adapted to produce an electrostatic attraction force and a base surface adapted to facilitate the application of the electrostatic attraction force and also a physical attraction force separate therefrom. The electrostatic and physical attraction forces can maintain a position of the electrostatic device relative to a foreign object via electroadhesion and/or via an additional manner that is separate from the electroadhesion. The physical attraction force can be a vacuum, van der Waals, and/or adhesive force, can be applied at less than all locations across the base surface, and may involve a one-time permanent attachment. The base surface can include a deformable surface portion that moves closer to the foreign object when the electrostatic or physical attraction force is applied. The physical attraction force can be sufficient to adhere the device to the object when the electrostatic attraction force is removed.
