    • A cleaning robot (10) for cleaning solar collectors comprises a gantry-type frame (16) configured to span a row (14) of solar collectors (12) and to define a corresponding cleaning space (24); and wheels (28) that are fixed to the gantry frame in order to move the latter and are associated with drive means. A cleaning tool (30) extends across the width of the gantry and is able to move in the cleaning space in order to be positioned with respect to the upper surface of the solar collectors (12), the cleaning tool being guided by means of guide rails (40, 42) fixed to the frame. Actuating means (54, 56) are provided to move the cleaning tool along the guide rails. At least one distance sensor (64) is arranged to determine a distance between the cleaning tool and a respective solar panel. A control unit (70) is connected to the distance sensor(s) and is configured to, continuously, adjust the position of the cleaning tool with respect to the solar panels of a row. The frame (16) comprises two lateral uprights (18, 20) that are connected in their upper part by a transverse member (22), and one of the guide rails (40, 42) is fixed to each of the lateral uprights (18, 20). The cleaning tool (30) has, towards each of its ends, a respective guide element (44) which cooperates with an associated guide rail (40, 42). The two guide rails (40, 42) define a plane of movement for the cleaning tool (30) and one of the guide rails (42) is mounted in articulated manner on one of the lateral uprights (20) so as to be able to pivot in the plane of movement. The actuating means (54, 56) comprise, at the two ends of the cleaning tool, a respective linear actuator connected to the frame, an actuating rod (54.2, 56.2) of which is connected to the cleaning tool (30) and to the guide element (44), respectively.
