Safety guidance: Product page: "Even if the power level is low, the WINBOT W3 OMNI will remain attached to the window for over 30 minutes."

Category FAQ: "WINBOT robotic window cleaner can work on tinted or colored glass as long as the surface is smooth and free of decals or stickers, cracks, obstacles under 4 mm, or frames under 2 mm. The window should also not be too small, curved, or irregularly shaped, and it must be free of condensation or oil stains.
