We drew from 34 years of cleaning experience when designing our Softbrush™ with extremely lightweight material, purposely built for the task of cleaning solar panels at the highest safety and quality level. Our patented Softbrush™ uses super soft squeegees that gently swipe away the dirt. Our reverse osmosis water filter removes minerals for a spot-free rinse, leaving absolutely zero residue. Our entire fleet of machines enable us to fit into rows where other "bigger" machines would never fit. With our unique solar cleaning robots, we clean commercial solar rooftops more efficient, safer and faster with significant less water consumption, unlike other cleaning options.
