Abstract:
A window cleaning apparatus comprises: a first cleaning unit, which is positioned on one side of a window, having at least one built-in first magnetic module comprising a magnet; and a second cleaning unit, which is positioned on the opposite side of the window on which the first cleaning unit is positioned, having at least one built-in second magnetic module, which comprises a magnet having an opposite polarity to the magnetic module of the first cleaning unit so as to generate magnetic attraction with the first magnetic module. The second cleaning unit comprises an induction electricity generating module for generating electricity by inducing the change in the magnetic field emanating from the first magnetic module and/or the second magnetic module into voltage by means of electromagnetic induction.
