Solar cleaning robot

I’m offering a unused Solar cleaning robot crawler. The Robot has never been used. The robot moves in all directions and cleans the panels thoroughly. It consumes a maximum of 20 liters of water per minute and can clean up to 1,170 square meters per hour. The battery lasts four to five hours. The robot is controlled by remote wireless remote control, the control distance can reach 150m, and the use is more flexible. The robot has a crawler chassis that allows it to move in all directions under remote control. It can go forward, backward, and turn left or right, ensuring complete and thorough cleaning of the solar panels from all angles. It is made for flat roofs.
