Clearing a path to the market soon will be the Winbot 7, a compactmachine billed by manufacturer Ecovacs Robotics as the first full-service window-washing robot.
The machine is compact at 1.6m high, 0.9m deep and 2.1m wide, which would make it an ideal candidate for Post Offices which often have under-utilised space that could easily house a book-printing machine.
