Advanced Product Features
1. Precision Engineering & Cleaning Efficiency
Dynamic Hydraulic Arm: The core cleaning roller brush is controlled by a sophisticated hydraulic system that allows for amplitude adjustment, extension, retraction, and 360° rotation.
Customizable Coverage: To maximize efficiency, the roller brush length is fully customizable (typically between 2.5m and 5m), offering wide coverage tailored to your specific panel layouts.
High-Pressure Cleaning: Integrated high-pressure pumps facilitate rapid water intake and efficient cleaning, significantly reducing water waste while removing stubborn debris.
2. Unmatched Power & Mobility
Off-Grid Power Independence: Featuring a 30KW generator set, the WLS-89 provides continuous power, making it the perfect choice for remote utility-scale sites without external power infrastructure.
All-Terrain Engineering: Equipped with rubber-coated steel wire tracks, the machine maintains low ground pressure to protect the soil and panel structures while offering a strong hill-climbing capability.
Industrial Durability: Built with high-quality AK Reducers and robust hydraulic components, the WLS-89 is designed for a long service life with a low failure rate in harsh environments.
3. Smart Operational Control
Dual Operation Modes: Operators can choose between wireless remote control for safety and convenience or manual control via the on-board control box.
Variable Speed Control: The working speed is adjustable from 0.5 to 10 m/min, allowing for a deep clean on heavily soiled panels or rapid maintenance on lightly dusted arrays.

Frequently Asked Questions (FAQ)
Q1: Can the WLS-89 handle uneven terrain in desert or mountain regions?
A: Yes. The WLS-89 features an engineering-grade track undercarriage and a dual-motor drive system designed specifically for high hill-climbing capacity and smooth operation on complex terrains.
Q2: How does the machine protect solar panels from damage?
A: The track pattern uses rubber-coated steel wire to ensure low ground pressure. Additionally, the hydraulic arm allows for precise adjustment of the roller brush amplitude to maintain a safe and effective distance from the panel surface.
Q3: Is the cleaning brush compatible with different panel sizes?
A: Absolutely. The roller brush length is fully customizable (2.5m–5m) to ensure optimal coverage for various photovoltaic array configurations.
Q4: Does the WLS-89 require an external power source during operation?
A: No. It is equipped with an internal 30KW generator set and a 100L diesel tank, providing independent, continuous power for long-duration cleaning tasks in remote areas.
Q5: How many operators are needed to run the equipment?
A: The machine is designed for easy operation by a single person using either the wireless remote control or the manual control box, which significantly reduces labor costs.
