Product name: Dualhead brushless motor cleaning brush Color: Rechargeable Overview A purposebuilt cleaning tool for photovoltaic panels, glass, and other large flat surfaces. Dual opposing brush heads and a water curtain spray system deliver balanced, singlehand operation with effective debris removal. The tool uses a pure copper brushless motor for steady torque and durability and an adjustable aluminum alloy telescopic pole to reach a wide range of heights. Key benefits Onehanded, balanced operation: Dualhead balanced power technology rotates brush heads in opposite directions to reduce torque and allow stable singlehanded use. The telescopic rod rotates for moplike backandforth scrubbing. Effective washing without excessive pressure: Four water spray devices at the front and rear of the brush create a fanshaped spray to form a strong water curtain that helps lift and carry away dirt and deposits. performance motor: Pure copper brushless motor, 300 W, 350 rpm for consistent speed and torque with reduced maintenance compared with brushed motors. Reach and adaptability: Telescopic aluminum alloy pole adjusts from 1.58 to 7.5 meters to access groundlevel panels up to rooftop arrays and other hardtoreach surfaces. Multiple power modes: Choose wired, rechargeable, or dualuse configurations to match jobsite power availability and mobility needs.

Components may arrive in batches due to logistics. Typical applications Solar panel cleaning: Routine cleaning of photovoltaic arrays on rooftops and groundmounted systems to remove dust, bird droppings, and surface deposits. Commercial glazing and skylights: Cleaning large glass facades, skylights, and atrium windows where reach and controlled water flow are required. Agricultural and greenhouse maintenance: Washing greenhouse panels and covers where gentle, uniform rinsing over wide surfaces is needed. Operation tips Adjust telescopic length and brush angle to match panel pitch and working height. Use the water curtain spray to prewet panels before scrubbing to help lift deposits. For extended jobs select wired or dualuse to avoid downtime; choose rechargeable for jobs where mobility and minimal cable management are priorities.
