A surface cleaning robot includes: a first cleaning unit arranged at a bottom of a main body; and a second cleaning unit arranged on one side of the main body. The second cleaning unit rotates under the action of a drive mechanism. Compared with the prior art, the surface cleaning robot cleans, by means of the second cleaning unit on one side of the main body, a surface to be cleaned. The driving of the second cleaning unit is independent from the walking of the surface cleaning robot, which is different from the prior art where bottom cleaning is performed while the surface cleaning robot walks. Therefore, rollers having a large volume are omitted. By driving the second cleaning unit to rotate, the cleaning effect is better improved.

An electrode film includes a first electrode pattern having a first set of parallel conductive electrodes and a second electrode pattern having a second set of parallel conductive electrodes disposed on a first surface of a transparent film, wherein elements of the first electrode pattern do not cross over elements of the second electrode pattern. A third electrode pattern having a third set of parallel conductive electrodes is disposed on a second surface of the transparent film, wherein the first, second and third sets of parallel conductive electrodes are arranged in an interlaced pattern. The electrode patterns are configured to be connected to respective power sources of electrical power supplying respective waveforms to generate a time-varying electric field pattern above a surface of the electrode film.

An automated building washing device generally includes one or more rotational brushes having a vertical rotational axis coupled to a window washing swing stage. The brushes are horizontally movable from end-to-end along the longitudinal direction of a window washing swing stage while rotating about their vertical axis so that a relatively large portion of building surface can be quickly cleaned.
