Electric Solar Panel Cleaning Brush: Our electric cleaning brush features an automatic rotating head designed to effectively eliminate stubborn stains from solar panels. Unlike traditional manual cleaning, this device offers a cleaning width of 60cm, significantly increasing work efficiency by up to 80% while reducing the need for manual effort. Versatile Cleaning Modes: This solar washing kit can be plugged directly into a power source for continuous operation, providing added convenience. It includes a water outlet for supplying water during cleaning, allowing you to easily switch between dry and wet cleaning modes. The dry mode is ideal for quick touch-ups, while the wet mode allows for thorough cleaning of every corner, with the option to use both modes together. Adjustable Length: Featuring a locking buckle structure, the telescopic cleaning rod can be easily adjusted to three lengths: 3.5m (11.4ft), 5.5m (18ft), and 7.5m (24.6ft). This design enables you to customize the pole length based on the height of the solar panel, accommodating various installation heights. Durable Construction: The portable cleaning roller brush is crafted from high-quality aluminum, striking a perfect balance between strength and lightweight design for great durability. The PV fiber brushes utilize high-density nylon filaments with moderate hardness, ensuring safe cleaning without damaging solar panels or other surfaces. Broad Applications: Ideal for cleaning large commercial areas, this brush is perfect for distributed factory roofs, extensive power plants, and solar installations in mountainous regions. Beyond solar panels, it serves excellently for outdoor window cleaning and can be used in various settings, including RV glass, store signage, and billboards.
