A surface cleaning device for cleaning a surface of a solar panel, wherein the surface cleaning device may include a motion delay assembly, a first dust carrying member and a second dust carrying member that are coupled to a motor; wherein the first dust carrier member and the second dust carrier member are wipers. The motor is configured to cyclically move the first dust carrying member and the second dust carrying member along a path. The motion delay assembly is configured to cyclically introduce a momentarily delay in a progress of the first dust carrying member along the path, while the second dust carrying member contacts the surface thereby reducing a gap between the first dust carrying member and the second dust carrying member, compress the air within the gap, and induce air that is compressed in the gap to exit the gap and progress along the surface and remove dust that precedes the second dust carrying member.
