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.

Strong Battery
The SolarWalker S1's battery can provide up to 4 hours of continuous operation on a single charge. It can effectively clean solar panels throughout an entire day with two batteries, allows it to cover an impressive area of 1.5-2MW of solar panel cleaning in a day.

Low Light Condition
The SolarWalker S1 is equipped with a sophisticated array of sensors that enable it to operate effectively even in low-light conditions, allowing it to work seamlessly during nighttime.

Smart Cleaning Patterns
With the support of high-precision algorithms and sensors, the SolarWalker S1 robot is able to autonomously and intelligently determine its cleaning patterns. This advanced technology enables the robot to efficiently and effectively clean solar panels without the need for manual intervention.

120cm Roller Brushes
Cover more and clean faster
Full-Auto & Semi-Auto Combined
Remote controllable with 2.4Ghz frequency, Long distance controlling: up to 100 meters.In complex environments, such as installation sites with irregular arrays or obstacles, remote controlling SolarWalker S1 is more efficient than running it in full-automatic mode.

When SolarWalker S1 cleans in dry condition, it can be fully automatically operated. Just put the robot on the right lower corner, press it to go. It returns to the starting point after one full array of solar panels are cleaned.
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.

Low-light or Night Working
SolarWalker S1 works in low-light condition or even in night time. It is suitable for applications in those areas with extreme high temperature during day time. Please pay attention to the surroundings (including obstables, gaps, people or animals on site when using it at night).
IP65 Waterproof Rating
ensures that the SolarWalker S1 can work in rainy days
***Rainy day working condition: Rainfall<=50mm, wind speed<=38km/h. Do not put your robot or use it in a thunderstorm


Modulized and compacted
1 person+1 SolarWalker S1 + 8 hours >=1.6MW Cleaning ***Reference On-site test data: Modules: 1400 pcs Mysolar 720W HJT modules, ground-mounted One array=70pcs, total 20 arrays, module size: 2384*1303mm Total volume: 720*20*70=1008000Watt (1.008MW) Full Automatic dry cleaning: 5 hours 10 minutes Average cleaning efficiency: 195KW/hour Semi-automatic dry cleaning: 4 hours 50 minutes Average cleaning efficiency: 215KW/hour
Detachable Parts
Roller brushes, watering frames and battery pack are all detachable designed for easier installation and maintenance.
Gap between two modules:<= 400mm, Hight between two modules: <=200mm


Efficient and Simple Operation
Timely OTA Upgrading and App Controllable
We are constantly working on optimizing the algorithms of SolarWalker S1 and will release updates as needed. This machine can be controlled through an APP. If your robot is the version with APP, you can operate up to 20 robots online simultaneously through the APP.
Powerful dual rotating brushes
Driven by high-speed rotating brushes, the machine can effectively remove floating dust, accumulated ash, bird droppings, and other debris. When paired with chemical cleaning agents, it can more efficiently clean stubborn or oily stains such as tree sap.

All Autonomous Planning, Full Area Coverage
SolarWalker S1 makes the cleaning patterns full automonously, and returns to the starting point after one full circle of cleaning.

Low-light or Night Working
SolarWalker S1 works in low-light condition or even in night time. It is suitable for applications in those areas with extreme high temperature during day time. Please pay attention to the surroundings (including obstables, gaps, people or animals on site when using it at night).
