Keep solar panels and other , hardtoreach surfaces clean with a professional electric cleaning system designed for thorough, efficient maintenance. The unit uses a speed, double nylon brush head and adjustable telescopic pole to remove dust, dirt, and bird droppings with controlled water spray for reduced water use and faster cleaning. Key benefits Thorough cleaning: speed rotating double nylon brush head provides strong friction cleaning to remove dust, sticky dirt, and bird droppings from photovoltaic panels and other surfaces. Extended reach: Telescopic aluminum pole extends from 2.1 meters to 7.5 meters in four sections, with a lock structure and 40 mm diameter for stable, adjustable use at multiple heights. Flexible power options: Use the included 24 V lithium battery (24 V 26 Ah) for cordless operation or the AC100240 V to DC24 V power converter with an 8 m cable for plugin use. A dual use option includes both. Watersaving spray: Threehole water spray combined with a 65 cm cleaning width reduces water consumption while maintaining cleaning coverage. Designed for efficiency: One operator can clean approximately 500 to 750 square meters per hour under normal conditions, with water use around 1.5 to 3 liters per square meter. Key specifications Total power: 240 W Voltage: DC 24 V Rotation speed: 320/min Brush head material: Nylon double brush head Brush head width / cleaning diameter: 65 cm Lithium battery: 24 V / 26 Ah (battery version) Power converter input/output: AC 100240 V to DC 24 V (plugin versions) Working hours per charge: 4 to 5 hours Charging time: about 8 hours Telescopic rod length: 2.1 m to 7.5 m (4 sections) Pole diameter: 40 mm Water consumption: about 1.5 to 3 liters per square meter Cleaning water consumption estimate: about 9 to 15 tons per MW Performance and usability Brush system: Largesize double brush head with speed rotation provides friction cleaning suitable for solar panels and a range of flat or slightly curved surfaces. Pole construction: Aviationgrade aluminum pole with locking sections for secure positioning and stable handling at extended lengths. Power management: Battery option delivers cordless mobility for areas without easy power access and approximately 4 hours of operation per full charge. Converter option allows continuous use from standard AC mains with an 8 m power cable. Water delivery: Threehole spray system supplies water to the brush area to improve cleaning effectiveness while limiting overall consumption. Included items by version 1.

Rooftop and commercial installations: Reach elevated panels or signage on buildings without scaffolding by extending the pole to access and clean installations safely from the ground. Vehicles and outdoor surfaces: Clean large RV windows, vehicle windshields, store signs, and billboards that require gentle but effective brushing and controlled water spray. User guidance and considerations Choose the version that matches your work conditions: select battery for mobility, plugin for continuous power, or dual use for both options. Consider the pole length and weight relative to your cleaning tasks to ensure ease of handling during extended use. Charge the battery fully before first use and allow about 8 hours for a full charge. Expect 4 to 5 hours of operation per charge depending on conditions. This cleaning system combines a durable nylon double brush, a longreach aluminum telescopic pole, and flexible power options to offer practical, repeatable cleaning for solar panels and other elevated surfaces.
