Abstract
A glass wiping device and a control method thereof are provided. The glass wiping device comprising a driver mechanism (110) and a follower mechanism (120); the driver mechanism (110) and the follower mechanism (120) are respectively provided with a first magnet unit and a second magnet unit; the magnetic force between the first magnet unit and the second magnet unit enables the driver mechanisms (110) and the follower mechanism (120) to be correspondingly adsorbed on the inside and outside of the glass, and the follower mechanism (120) can follow the driver mechanism (110); the driver mechanism (110) or the follower mechanism (120) is provided with a pressure induction unit and a pressure indicating device (121) thereon; the pressure induction unit comprises a pressure sensor (41) and a controller (42); the pressure sensor (41) is used to sense the pressure of the driver mechanism (110) and the follower mechanism (120) against the glass; after receiving a pressure signal transmitted by the pressure sensor (41), the controller (42) controls the pressure indicating device (121) to display a relevant state. The control method comprising the following steps: a), placing the driver mec…
