Best window robots for large windows

Window robots with the pane rating, the tank and the route planning for floor-to-ceiling glass.

A patio door or a stairwell pane is where a window robot earns its keep, and where a small one runs out of water halfway up. Weighted on the size of pane the maker rates it for, how much glass one tank covers and whether it plans a route rather than bouncing off the frame.
