Maintain peak efficiency of your solar arrays with the WLS-4 Double Head Solar Cleaning Machine. Engineered by Wuxi Wanlv Intelligent Technology Co., Ltd., this high-performance tool is designed to tackle the toughest environmental contaminants, from desert dust to stubborn bird droppings.
Core Features & Advantages
1. Superior Stability with Double Head Balance Design
The WLS-4 features a unique structural design where the rotation of the two brush heads is balanced by opposing forces. This ensures maximum stability during high-speed rotation, preventing “wandering” and allowing for a more consistent deep clean.
Cleaning Width: 65cm for high-efficiency coverage.
Dual Application: Seamlessly switch between dry cleaning for light dust and water washing for stubborn grime.
2. Versatile Telescopic Reach
Equipped with premium aluminum alloy telescopic rods, the WLS-4 allows operators to clean panels from a distance of 3.5 to 7.5 meters. This eliminates the need for ladders or walking on fragile panels, ensuring operator safety and equipment longevity.
3. All-Terrain Water Supply Solutions
- Standard Lithium Pump: Achieve a short-distance water supply of up to 50 meters.
- High-Power 220V Pump: Capable of driving water across long distances of 100-200 meters.

Frequently Asked Questions (FAQ) – WLS-4 Solar Cleaning Solutions
Q1: Why choose the WLS-4 double-head design over a single-head brush?
A: The WLS-4 utilizes a double-head balanced power structure where the rotation of the two brushes counteracts each other’s torque. This prevents the “walking” or “drifting” effect common in single-head tools, providing much stronger stability and higher cleaning efficiency for professional-grade maintenance.
Q2: What is the actual runtime for the WLS-4-2 Lithium Battery version?
A: The Lithium-powered version is equipped with a high-capacity 24V 26AH battery pack. It provides a continuous working time of 3.5 to 4.5 hours on a single charge. The charging cycle takes approximately 6-7 hours, making it ideal for daily off-grid cleaning schedules.
Q3: Can the WLS-4 handle both dry cleaning and pressurized washing?
A: Yes. The WLS-4 is a versatile system designed for both dry cleaning and washing applications. The high-speed rotation (300-350 r/min) combined with a water spray system effectively removes everything from fine desert dust to stubborn, sticky bird droppings.
Q4: How does the system perform in environments without a direct water or power source?
A: For non-electric environments, you can utilize the Lithium Version (WLS-4-2) which includes a dedicated battery backpack for maximum mobility. If a water source is unavailable nearby, the system can be paired with a gasoline-powered pump to overcome environmental limitations, supporting long-distance water supply of up to 200 meters.
Q5: Will the brush material damage or scratch the solar panel surface?
A: Not at all. The WLS-4 uses high-quality Nylon bristles specifically selected for their durability and softness. This material ensures a deep clean without compromising the integrity of the photovoltaic glass, even during high-speed rotation.
Q6: Is the telescopic rod adjustable for different installation heights?
A: Yes, the system features a premium Aluminum Alloy telescopic rod with three length options: 3.5m, 5.5m, and 7.5m. This allows operators to safely clean large-scale arrays from the ground or from maintenance walkways without stepping on the panels.
Q7: Does the manufacturer support custom branding or OEM orders?
A: Yes. Customized logos and designs for mass production are available upon request, provided the necessary authorizations are in place. While sample orders are delivered quickly, mass manufacturing typically follows a 10-20 day lead time.
