Roomba for Solar Panels

Using a spinning scrub brush and squeegee combination—plus an internal reservoir of detergent—the robot can clean over 1,000 square feet every hour, and everything from dust to bird droppings. It can keep on working even when a solar panel is tilted up to 30 degrees, and can span gaps up to 20 inches across allowing it to crawl from one panel to another.
