Best window cleaning robots

Window robots ranked on how well they clean, how hard they hold on and what they do when the power fails.

A window robot is the only home robot that works against gravity, so the questions are different. Does the glass come out streak-free? How hard does it hold on, and for how long after a power cut? Which panes does it fit, and does it find its own way round the handle? Ranked on the default weighting, with cleaning and safety carrying forty per cent between them.
