SolarWalker S2
Introducing the upgraded Mamibot SolarWalker S2, a fully automatic robot cleaner designed to keep your PV solar panels operating at peak efficiency. Capable of both dry and wet cleaning, the S2 effectively cleans panels with installation angles up to 25 degrees under wet conditions and 25 degrees in dry settings.
The world's first PV solar panel robot cleaner equipped with Tri-Eye™ SLAM navigation, OTA upgrades, FPV live video transmission, and vision + ultrasonic anti-fall sensors, the S2 can be controlled via app or remote. With an upgraded battery, it operates for 5–6 hours on a single charge .The Mamibot SolarWalker S2 cleans across solar panels with gaps of up to 50mm,it’s compatible with M2/M4/M6/M10/G1/G12 panel frameworks.By automatically removing dust, grime, and debris, the S2 ensures your solar panels generate maximum power output—delivering a rapid return on investment.

The wet and dry combined washing system tackles even the most stubborn dirt for a deep, streak-free clean.The SolarWalker S2 consumes 5–6liters of water per minute in Wet cleaning.
Wet and dry Cleaning Supported
Smart Full Autonomous Operation with Complete Area Coverage
SolarWalker S2 cleans 900-1800 sqm per hour in full automatic operations. After completing each cycle, it automatically returns to its starting position—delivering hands-free efficiency with zero manual intervention.

The SolarWalker S2 delivers high performance, revolutionizing your routine maintenance and significantly boosting your energy output.


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.

App &Remote controllable
SolarWalker S2 receives continuous algorithm optimization through regular updates.
OTA Upgrading


Monitor SolarWalker S2's cleaning path in real time with FPV live transmission, streaming the video to a remote controller with a 5.5-inch display for intuitive tracking and visual confirmation of cleaning progress.
Real-Time FPV on Controller
SolarWalker S2 operates reliably in extreme environments, withstanding ambient temperatures from -20°C to 50°C .
Temperature-Resistant Performance


The SolarWalker S2 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.
Low-light or Night Working

Equipped with an explosion-proof battery for high stability and enhanced safety, the SolarWalker S2 operates continuously for up to 5–6 hours on a single charge.
Anti-explosion Battery
Roller brushes, watering frames and battery pack are all detachable designed for easier installation and maintenance.One man carries, installs,operates and delivers one robot easily.
Detachable Parts

The Mamibot SolarWalker S2 is fully upgraded from the S1 model, significantly enhancing safety with added Tri-Eye™ SLAM NaviTech and Four-direction anti-fall sensors, an explosion-proof battery, and an IP65 protection rating.


The SolarWalker S2'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.
IP65 Protection Grade
Visual and Four-direction anti-falling sensors provide flawless detection and operation on the panels, protecting your asset.
Visual+ Four-direction Anti-falling


User-Friendly Operation System
The SolarWalker S2 features user-friendly operation and broad compatibility, working with nearly all types of solar panels and frame systems.

Built for Real Sites
With up to 25 degrees of gradeability in wet washing mode, it conquers sloped installations. A longer running time of up to 6 hours per charge ensures it can handle large-scale projects.
The Mamibot SolarWalker S2 cleans across solar panels with horizontal gaps of up to 50mm,vertical gaps up to 20mm, ensuring thorough coverage even on widely spaced arrays.
Cross Horizontal Gap up to 50 mm
