Extra-wide nylon brush: This large-size brush offers a cleaning width of up to 1.1 meters (3.6 feet), allowing you to cover more area with each pass. It is designed for commercial use, enabling one person to clean 1000-2000 square meters per hour for increased efficiency. Carbon fiber telescopic rod: Featuring a telescopic rod with secure lock design, this lightweight and sturdy brush easily reaches high or hard-to-access panels with one-handed control. Power supply: The electric cleaning equipment is adaptable to 100V- mains electricity and includes a power converter for versatile use. Water supply: This cleaning machine provides two modes: dry cleaning and water cleaning. Water friction helps remove dust and dirt from panels, and it supports a 7mm inner diameter water pipe connection. Gentle yet powerful cleaning: The widened brush uses high-density nylon filaments with moderate hardness to safely remove dirt without scratching surfaces. An adjustable angle design ensures a smooth and automatic fit during the cleaning process.
