【HIGH-EFFICIENCY MOTORIZED BROOM】Powered by a 150W brushless copper motor and a rotating brush spinning at 380 RPM, this solar panel cleaner extends the cleaning width to 24 inches (60 cm) and improves efficiency by 80% compared to manual wiping. It effortlessly removes stubborn dirt, bird droppings, and dust while significantly reducing physical exertion. The brushless motor lasts longer, is quieter, and stays cool. 【ADJUSTABLE TELESCOPIC POLE】This Solar Panel Cleaning Kit is available in three lengths: 3.5 m / 5.5 m / 7.5 m, with lightweight aluminum poles to accommodate different roof heights. The reinforced aluminum alloy pole (1.1 mm thick) is sturdy and won't bend easily. Reach terraces, two-story roofs, or solar installations without ladders or scaffolding. 【360° SELF-ADAPTIVE HEAD】The telescopic cleaning brush's compact PBT bristles are arranged in rows, lifting dust like a broom and penetrating panel crevices. The rear silicone squeegee acts like a windshield wiper to remove dirty water, minimizing water streaks and secondary splashes. With a cleaning width of 60 cm, up to four rows of vertical solar panels can be cleaned simultaneously. 【WET AND DRY MODE】Equipped with three dual-nozzle outlets for enhanced water flow, this solar panel cleaning robot allows for a seamless transition between dry dusting and deep wet cleaning. The cables are encased in a durable mesh, preventing cuts or electrical hazards from friction. The fully waterproof design ensures reliability even in the rain or outdoors. Safety and efficiency—both are guaranteed. 【ALL-IN-ONE OUTDOOR】This water-powered telescopic brush cleans not only solar panels, but also RV roofs, boat decks, canopies, awnings, signs, windows, trucks, and exterior siding. Lightweight and foldable design for compact storage. For homeowners or professionals, a single system meets all your outdoor cleaning needs.
