Lumobot Solar Panel Cleaning Robot and LumoOS

Lumo Robotics (LUMO ROBOTICS LTDA) is a Brazilian company based in Louveira, state of Sao Paulo, that builds robots and software for solar plant maintenance. It describes its offer as robotic upkeep, under the tagline Zeladoria Robotica 4.0. In February 2025 a trade report said it raised R$1 million in its first round, led by angel investors and Gera Climate Ventures.

The Lumobot is a solar panel cleaning robot with two nylon brushes that clean in a single pass, an internal battery, IP65 protection, all-terrain traction through the panel frame and automatic firmware updates. It is paired with LumoOS, an O&M management platform with a dashboard showing cleaning data. The site names customers such as Gera, Araxa and Navi and case studies with Ambar Energia and WM Renovaveis.

• Dual-brush cleaning: two 0.3 mm nylon brushes clean the module in a single pass.
• Low water use: 1 to 2.5 litres per module.
• Self-contained power: internal battery with no electrical extension cords.
• Rugged design: IP65 protection and all-terrain traction through the panel frame.
• LumoOS platform: O&M dashboard showing cleaning data such as average speed.
• Remote upkeep: automatic firmware updates.

Cleaning of ground-mounted solar plants in Vietnam's south-central region using a low-water semi-autonomous robot. O&M contractors tracking cleaning productivity through the LumoOS dashboard. Small and medium solar farms that cannot justify fully autonomous fleets.

The site reports a 285 percent productivity increase, 85.4 percent water savings and 60 percent time reduction in its case studies, with 144 MW served. Water use is stated as 1 to 2.5 litres per module. The internal battery removes the need for extension cords. NR12 safety-standard compliance is stated.

Solar plants in dusty or water-limited areas need cleaning that cuts water use and labour time, and low-water semi-autonomous robots serve this need. Vietnam's ground-mounted plants face similar soiling and labour costs, though the company does not state any Vietnam presence.
