SolarWalker S1
The Mamibot SolarWalker S1 is the pioneering fully automatic robot cleaner designed specifically for solar panel maintenance. It effectively cleans panels with installation angles of up to 15 degrees in wet conditions and 20 degrees in dry conditions. With a single full charge, the SolarWalker S1 can operate continuously for up to 4 hours, making it capable of completing wet cleaning for 1.7MW within a single day (8 hours). This innovative cleaning solution is ideal for solar parks, solar farms, rooftop installations, and ground-mounted photovoltaic systems.

When operating in dry conditions, the SolarWalker S1 can clean fully automatically. Simply place the robot at the bottom-right corner and press start. After cleaning an entire solar panel array, it will automatically return to the starting point.
When SolarWalker S1 cleans in wet condition,hold the water pipe and press the robot to start it. It will follow a smart cleaning pattern which is supported by groups of high-precise sensors and intelligent algorithm.

The SolarWalker S1 works in both wet and dry conditions, cleans most types of solar modules with M2/M4/M6/M10/G12 solar cells.
Applicable for Most Types of Solar Panels

Powerful Dual Rotating Brush System
Powered by high-speed rotating brushes, the system can effectively remove floating dust, accumulated ash, bird droppings, and other debris. When combined with chemical cleaners, it can eliminates stubborn or oily residues like tree sap more efficient.
Temperature-Resistant Performance
SolarWalker S1 operates reliably in extreme environments, withstanding ambient temperatures from -20°C to 60°C and module surface temperatures up to 85°C.

Smart Autonomous Operation with Complete Area Coverage
The SolarWalker S1 intelligently plans optimal cleaning paths for full-area systematic cleaning. After completing each cycle, it automatically returns to its starting position—delivering hands-free efficiency with zero manual intervention.


Anti-Fall Protection
SolarWalker S1 features integrated sensors that prevent the unit from falling off panels during operation, ensuring safe and secure cleaning.
IP65 Weatherproof Protection
The SolarWalker S1's industrial-grade IP65 waterproof design delivers reliable performance in rainfall up to 50mm/h and winds up to 38km/h. Do not use it or place it outside in a thunderstorms or extreme weather conditions.


The SolarWalker S1 delivers up to 4 hours of continuous runtime on a single charge. It enables full-day cleaning capacity with 2 batteries, achieving complete coverage of 1.5-2MW solar arrays in one day. This robust power solution ensures maximum productivity.
Strong Battery

SolarWalker S1 receives continuous algorithm optimization through regular updates. APP control is available as an optional feature. If your robot is the version with APP, you can operate up to 20 robots online simultaneously through the APP.
High Efficiency and User-Friendly Operation Seamless OTA Updates and App-Controlled

The SolarWalker S1 incorporates advanced high-precision algorithms and sensor systems to intelligently determine optimal cleaning patterns in real-time. The system's intelligent path planning capability ensures thorough coverage while maximizing cleaning efficiency, eliminating the requirement for manual direction or intervention.
Intelligent Autonomous Cleaning Technology
Low-light or Night Working
The SolarWalker S1 features advanced sensor technology that ensures reliable operation in low-light conditions, making it ideal for nighttime cleaning. This capability is particularly valuable in regions with extreme daytime temperatures. For optimal safety during night use, please ensure the work area is clear of obstacles, gaps, and personnel or animals.
