Size: 7.5m; Color: Mainselectricity Handheld Solar Panel Cleaner Window Cleaner for photovoltaic panels, windows, exterior walls and other hard to reach surfaces. Designed to restore and maintain surface cleanliness without scratching, reduce manual effort, and reach or angled installations with no dead corners. Key benefits Restores panel efficiency by removing dirt, dust and grime that reduce output. Dry and wet cleaning modes allow fast surface wipe or deep washing as needed. Reaches or angled installations safely. Telescopic pole extends up to 7.5 m and the brush head rotates automatically through 360 degrees so you can clean surfaces without repositioning or climbing. Protects surfaces. Soft nylon bristles clean effectively without scratching glass or panel surfaces. Improves productivity. 60 cm cleaning width and 150 to 300 rpm brush rotation increase coverage and reduce cleaning time. Main features 360 degree automatic rotating brush head with adjustable angle to maintain full contact with the panel surface and avoid blind spots. Two cleaning modes: dry cleaning for quick decontamination and water washing for deeper cleaning. Water feed integrated in the pole. Telescopic aluminum alloy pole available in three configurations: 3.5 m, 5.5 m, and 7.5 m. The 7.5 m option comprises five sections with 150 mm per section for stable extension.
