Safety & placement (manufacturer-sourced)

Window-cleaning robots operate at height on glass. This page only reproduces placement and failure-mode guidance published by the manufacturer; where none was retrieved, we say so and direct you to the manual shipped with the unit. We do not improvise safety advice.

Manufacturer guidance: Manufacturer-published (via amazon.com bullet): 'SECURE ATTACHMENT: Built-in safety mechanisms keep the robot firmly attached to vertical glass surfaces while cleaning.' No manufacturer-published placement instructions, failure-mode documentation, safety tether, or safety-cord length retrieved this build — beyond the above, guidance = not published/retrieved this build.
