DoubleHeaded Brushless Motor Cleaning Brush (Size: 5.5m) Overview A purposebuilt cleaning tool designed for photovoltaic panels and large flat surfaces. Dual rotating heads provide balanced operation that a single operator can handle. The brush integrates a pure copper brushless motor, a telescopic aluminium alloy rod, and a water curtain system to remove dust and grime efficiently on sites without fixed electrical supply. Key benefits Oneperson operation: Dualhead balanced rotation cancels torque so the unit can be held and guided with one hand for controlled cleaning. Longlasting motor: Builtin pure copper brushless motor rated for extended service life and improved resistance to dusty conditions. Faster rinsing: Four water sprinklers form a fanshaped water curtain that pushes dirt off panels and increases cleaning efficiency. Adjustable reach: Telescopic rod locks at multiple positions to reach panels at ground level up to multirow vertical arrays. Flexible power options: Available in powered, lithium battery, or dualuse configurations to suit onsite power availability. Features Dualhead balanced power technology: Heads rotate in opposite directions for balanced handling and moplike backandforth brushing motion. Pure copper brushless motor: 24 V motor rated at 300 W, running at 350 r/min. Water curtain quick cleaning: Front and rear sprinklers combine into a continuous spray to drive sewage and dust down the panel surface. Brush material: Newy nylon yarn for consistent scrubbing without damaging glass surfaces. Telescopic rod: Aluminium alloy construction with a locking buckle structure for secure, adjustable lengths. Compact transport lengths for each rod option to simplify storage and handling.

Industrial and agricultural lighting maintenance: Remove dust and bird droppings from large lighting fixtures and arrays in open factories, greenhouses, and farms. Remote installations and mountain solar plants: Portable battery or dualpower options allow cleaning on sites without grid access. How it solves common problems Reduces operator fatigue: Balanced dualhead rotation minimizes countertorque and stabilizes handling during extended cleaning tasks. Improves cleaning throughput: Combined mechanical brushing and water curtain rinse accelerate dirt removal compared with manual wiping. Adapts to site constraints: Telescopic reach and multiple power configurations enable use on roofs, ground arrays, and remote locations without fixed electricity.
