Safest window cleaning robots

Window robots ranked on grip, power-cut backup, the safety rope and fault detection — for glass above the ground floor.

On an upstairs window the only specification that matters is what the robot does in the minute after the mains fails. Weighted on suction, on how long it holds on without power, on the rope and its rating, and on whether it checks itself for a fault before it lets go.
