Remote-controlled crawler-type solar panel cleaning robot
A semi-automatic smart cleaning solution. Safe, efficient panel cleaning with the RHINOSTAR EC6 by Rhino Stone Tech.
With a lightweight body and two adaptive, extra-wide 1.3 m floating roller brushes at the front and rear, it hugs the panel surface and cleans without blind spots. A parking mode prevents brush deformation to extend brush life, and front and rear anti-fall systems greatly improve safety, handling diverse scenarios and complex terrain.
