LINCINCO

Dongguan Lingxin Intelligent Technology has released LINCINCO, a robot that sticks to a window and wipes it. Cheaper machines often miss the frame because they only guess where the glass ends. This one uses a camera and sensors, checks the frame 30 times a second, and wipes in a zigzag. On a very dirty window it slows down and sprays more water. If it has cleaned the same window before, the next clean can be about a quarter faster.

Two fans hold it on the glass, at up to 3,200 pascals, about the weight of 6 to 8 kilograms when the robot is still. A safety rope, a spare battery, and a drop sensor catch it within a fifth of a second if the suction slips. It cleans 1.2 to 1.8 square metres a minute, runs 40 to 55 minutes on a charge, and handles glass up to 34 millimetres thick with a magnetic frame.

The company started in 2018, with factories in Dongguan and Hengyang, and more than 600 people. The window robots carry the European CE and RoHS marks. Shops that want to sell the robot under their own name can change the colour, the logo, the box, and the phone app.
