Professional electric solar panel cleaning brush effectively removes stubborn dirt with a 150-300 rpm rotating head and water pump, featuring a 60 cm cleaning width, 7-8 meter water lift, and 45-60 liters per minute flow rate for thorough cleaning. 360° continuous rotation brush head adapts to any panel angle, is height-adjustable to eliminate blind spots, and includes a replacement head for uninterrupted use on uneven surfaces without damaging the outer layer. Rechargeable and portable power solution operates wirelessly with a battery, supporting large projects in off-grid areas using a 5-9 meter integrated pipe and 10 meter extension for mountain solar plants and factory roofs.

Adjustable telescopic pole made of lightweight aluminum alloy extends to 3.5m, 5.5m, or 7.5m for hard-to-reach panels, combined with a 60cm wide rotating brush for ergonomic and industrial-grade performance.
