Automatic cleaning apparatus for solar collectors, photovoltaic panels, windows and similar surfaces

An autonomous apparatus for sweeping dust deposited on the surface of a photovoltaic panel (PVP) or similar, CHARACTERIZED in that it comprises an elastic brush 10 formed by an elastic cord 20 having integrated filament bristles 30 that protrude radially to the cross-section of the cord 20;

• wherein the ends of the elastic cord 20 are attached through rolling hooks 40 to discs 50 that rotate by means of motors 60 that support said discs 50, and wherein the rolling hooks 40 are attached at each end of the respective elastic cord 20 to the edges of the discs 50 in order to prevent continuous torsion of the elastic cord 20;
• and wherein the motors 60 rotate synchronously producing stationary waves in the associated elastic brush 10.
