Efficient Cleaning: Electric rotating roller brush helps remove dust, pollen, bird droppings and surface debris from solar panels faster than manual brushing. Reach More Panels: Available in 11.5 FT, 18 FT and 24.6 FT lengths to help clean rooftop or ground-mounted solar panels with better reach. Dry & Wet Use: Supports both dry brushing for light dust and water-assisted cleaning for heavier dirt, giving more flexibility for different panel conditions. Easier One-Person Operation: Long telescopic design helps reduce repeated close-range scrubbing and makes large-area panel cleaning more efficient and less tiring. Built for Outdoor Jobs: Durable motor and water-resistant construction are designed for regular outdoor solar panel maintenance in rooftops, farms and commercial sites.
