“We are very satisfied with all the work. The equipment is great, robust, easy to operate and very efficient.”
Luebert Gomes
O&M Technician · Véritas Energia Solar

“We significantly reduced labor and water consumption, achieving greater efficiency and a perfect clean. After testing other robots with poor results, the TCR-W1 exceeded expectations and comes with excellent technical support.”
Samuel Felipe
Field Lead · AEVO Energia

“Excellent equipment, it's a pleasure to work with it. No more battery issues, and the modules are all standardized after cleaning. The robot operates fully autonomously, stopping on its own at the end of each row.”
