Water-free, portable cleaning bot for rooftop solar


Bengaluru-headquartered Aegeus Technologies has introduced the Shreem cleaning bot exclusively designed for rooftop solar installations. The robot is fully autonomous and weighs only 5 kg (with batteries), portable enough to carry in a backpack. 

Shreem can be operated through a web-based app from any remote location, and overcomes the problem of accessibility for dangerous or difficult-to-reach rooftop installations. The bot, being Bluetooth-enabled, can also be operated manually using a mobile app or through an RF remote-operated controller. It can be preset to start at a desired time of the day automatically.

Shreem uses airwash technology to clean the panels, requiring no water or any harmful chemicals. It consists of two sets of wiping brushes (axial and radial) made of microfiber cloth. Controlled airflow blows the dust off the panels efficiently. The radial brush ensures any leftover dust on the edges is also blown off.

The bot uses an intelligent algorithm and sensors to detect edges and move in a straight path covering the entire area. It aligns automatically to account for undulations or uneven surfaces. Further, it is intelligent to differentiate between the end of the table and gaps between tables. The bot uses a computational neural network to train itself about the number of rows, columns, modules, inclination angle, path planning, and direction for effective operation.

Shreem comes with a solar-powered docking station, which keeps monitoring weather parameters like the rain, wind speed, etc. The bot will return to or continue to be in the docking station if the weather is unsafe for its operation.

Shreem can clean around ​200 panels an hour​. It is powered by a 10Ah lithium-ion battery pack with a life of around 2000 cycles.
