Product: Dualhead Photovoltaic Panel Cleaning Machine Size: 7.5M Color: Dualuse Key benefits Cleans large photovoltaic areas from the ground using a telescopic, waterfed pole for safer and faster maintenance than manual methods. Dual rotating brush heads provide continuous water and brushing action to remove dust, debris, and stuckon dirt without scratching panels. Nondestructive adaptive brushing: density nylon bristles and an automatic angle adjustment follow panel tilt and surface contours to avoid damage. Flexible power options let you work ongrid, offgrid, or both with the dualuse configuration. Main features Dual brush heads, 65 cm cleaning width total, counterrotating at 380 rpm for effective scrubbing with water feed. Telescopic rod adjustable from 1.35 m up to selectable maximum lengths: 3.5 m, 5.5 m, or 7.5 m to reach or distant panels. Water supply: 20 m hose included for remote access and continuous rinse. Power: 480 W motor for consistent brush rotation. Battery option: lithium battery with around 4 to 5 hours runtime. Charging time 8 to 10 hours. Battery capacity listed at 28 Ah. Lightweight design: brush assembly approximately 4 kg for easier handling during extended use. Bristle material: durable nylon filaments that resist shedding and avoid surface damage. Rolling brush speed: 380 rpm for steady, effective cleaning action. Power configurations Plugin powered: includes power converter and cables for continuous operation from AC supply. Batterypowered: portable lithium battery with backpack mounting for offgrid cleaning. Dualuse: includes both battery and power converter for maximum flexibility.

Commercial and industrial rooftops where longreach cleaning is needed without roof access or scaffolding. Residential photovoltaic systems, windows, billboards, and glass curtain walls where a gentle, nondestructive brush and water feed allow cleaning from the ground. Technical specifications Motor power: 480 W Brush width: 65 cm cleaning diameter Brush rotation speed: 380 rpm Rod length options: up to 3.5 m, 5.5 m, or 7.5 m (telescopic, extends from 1.35 m) Battery capacity: 28 Ah Battery runtime: approximately 4 to 5 hours Charging time: 8 to 10 hours Water hose length: 20 m Brush material: nylon wire Approximate brush weight: 4 kg Why this product solves common problems Reduces the need for ladders or roof access by enabling groundbased cleaning with extended reach. Keeps panel surfaces clean without abrasive contact by using nylon bristles and adaptive head alignment. Offers operational flexibility with plugin, battery, or dual power configurations to match onsite conditions. Notes for safe and effective use Select the appropriate rod length for site height and accessibility. Ensure water supply and power configuration are compatible with the chosen cleaning location. Charge the battery fully before remote jobs to maximize runtime. Inspect hoses and electrical connections before each use.
