WATER CURTAIN QUICK CLEANING TECHNOLOGY: Rotating brush for photovoltaic panels has 4 water spray devices at the front and rear ends of the brush head to spray fan-shaped sprays connected into pieces, forming a strong water curtain to quickly drive the sewage off the photovoltaic panel, improving the cleaning efficiency by 75%. DEEP CLEANING: Dual brush heads solar panel cleaner brush, the electric brush rotates at high speed to spray friction, while powerfully removing dust and sticky dirt on the of photovoltaic panels. BRUSHLESS MOTOR: The brushless technology reduces the excitation loss and carbon brush loss, has good stability, and greatly improves the product life, At the same time, the motor adopts an integrated IP7 waterproof structure, which is water-proof and can still work reliably in rainy days INDUSTRIAL GRADE THICKENED TELESCOPIC ROD: Water fed pole is adopted locking buckle structure, the length of the telescopic rod can be adjusted arbitrarily 24 ft/7.5 m, and it can be easily cleaned from the feet to the bottom. APPLICATION: Electric photovoltaic cleaning machine for commercial large-area clean environments without electricity such as distributed factory roofs, large power plants, and mountainous solar power plants.
