Mamibot SolarWalker S2 LITE
Mamibot SolarWalker S2 LITE is a semiautomatic solar panel cleaning robot designed for commercial rooftops and smalltomedium PV installations.
With a LightCore™ ultralightweight design, the unit weighs only 14.2kg without battery and approximately 18kg with battery. It supports dry and wet cleaning modes through the HydroFlex™ dualmode cleaning system and provides up to 10 hours runtime in dry singlebrush mode. With SpeedFlex™ 3 adjustable brush speeds (120–160rpm) and 3 adjustable moving speeds (30–50cm/s), it adapts to different dirt levels and cleaning efficiency needs. Front dual ultrasonic antifall sensors combined with the SafeEdge™ multilayer safety system provide enhanced protection on inclined surfaces, while the IP65 waterproof and dustproof rating ensures reliable operation in harsh outdoor environments. Comes standard with a single 0.8m brush, with optional dual brushes or 1m/1.2m brush available through the BrushFlex™ modular brush system. Compatible with all types of industrial/commercial framed PV modules, with a maximum horizontal gap crossing of 300mm, vertical gap crossing of 20mm, and tilt angle capability of <33° for dry cleaning and <25° for wet washing. TÜVcertified with 20,000 microcrack tests under the CrackProof™ protection design—delivering reliable and efficient longterm cleaning for your PV power plant.
