Size: Battery. Color: A (Row Brush) Overview A batterypowered solar panel cleaning machine designed to keep panels of dust, dirt, and bird droppings to help maintain power generation. The unit uses a 60 cm rotating roller brush on a 7.5 m telescopic pole for extended reach and fast, even cleaning. Two brush head types allow efficient dry or waterassisted cleaning. Lightweight balance and a 24 V lithium battery make rooftop and window cleaning practical without constant ladder repositioning. Key benefits Improves panel performance by removing dust, dirt, and bird droppings that reduce output. Large 60 cm rolling brush covers a wide area to speed up cleaning and reduce job time. Rotating friction brush delivers consistent pressure and thorough cleaning without shedding. Two brush head options let you switch between dry dusting and water washing for different soils. 7.5 m telescopic pole extends reach for roofmounted arrays and windows while remaining manageable by one operator. Battery power allows cordless operation for up to 4 hours between charges, increasing mobility on large or remote sites.
