Application Scenario

Core Features
1. High Efficiency & Excellent Cleanliness
Two operators can take turns operating one machine to achieve a maximum cleaning capacity of 1.5 MW per day. Boasting a cleaning efficiency of up to 1000 m²/h, it uses sufficient water to flush panels thoroughly. It effectively removes floating dust and accumulated dust, and can clean light to medium oil stains when used with neutral detergent, ensuring optimal panel cleanliness and power generation efficiency.
2. Lightweight Design & Damage-Free Operation
Through structural optimization and lightweight design, the robot’s net weight is well-controlled. It has passed third-party testing to confirm no damage to PV panels during long-term operation, protecting the integrity and service life of your photovoltaic components.
3. Modular Design for Easy Handling
Adopting a modular structure, the robot’s usage, cleaning head, and battery can be quickly disassembled and assembled. This design greatly facilitates transportation and carrying, reducing logistics and on-site deployment costs, especially suitable for scenarios requiring frequent movement between different cleaning areas.
4. Flexible Remote Control Operation
Supports remote control with a maximum control distance of 150 meters, allowing operators to complete cleaning tasks from a safe area. It eliminates the need for manual climbing or close contact with panels, improving operational safety while adapting to different cleaning scenarios with ease.
5. Reliable Power Supply & Long Working Hours
Equipped with a ternary lithium battery (25.2V 25.6Ah) that provides a full battery life of 4 hours. The battery can be quickly replaced (spare battery optional) for continuous operation. The charging time is 5 hours, and the charger is compatible with EU and JP standards, meeting the needs of global users.
6. Versatile Adaptability & Enhanced Cleaning Options
