Electric Solar Panel Cleaning Brush, 3.5 m / 11 ft, Lithium Battery Powered Key benefits Faster cleaning: Automatic rotating dual brush heads reduce manual effort and cut cleaning time by up to 80 percent compared with traditional wiping. Thorough stain removal: Dual brush head rotation with balanced force targets stubborn dirt, dust, and bird residue for a cleaner panel surface. Portable and cordless: Powered by a lithium battery for untethered operation where access or water supply is limited. Features Automatic rotating brush head system that maintains balanced force across the cleaning surface for consistent results. 3.5 m / 11 ft reach suitable for rooftop and groundmounted panels; provides extended access without excessive bending or ladders. Lithium battery power for cordless operation and flexible placement during cleaning tasks. Designed specifically for solar panel surfaces to remove buildup that can interfere with light exposure. Performance and use Designed to improve cleaning efficiency and reduce labor compared with manual wiping methods. Brush action focuses on removing stubborn residues while minimizing the need for repeated manual scrubbing. Cordless design allows easy maneuvering across arrays and around obstructions. Typical applications Residential rooftop solar panel cleaning and maintenance. Small commercial installations and carport or canopy panels. Offgrid and remote solar arrays where water or mains power is not readily available. What to expect A durable, motorized brush assembly that rotates automatically and distributes force evenly for steady contact with the panel surface. A compact, extendable reach of 3.5 m / 11 ft to address panels at moderate heights without complex setup. Batterypowered operation that enables cleaning across multiple panels in one session, depending on battery charge and conditions. Note Intended for cleaning solar panels. Performance depends on surface condition, environment, and usage technique.
