The present invention relates to a magnetically attached-type window cleaning apparatus in which a pair of cleaning units, which are attached to either surfaces of a window by means of magnetic attraction, clean inner or outer or both sides of the window simultaneously while moving along the surface of the window. The window cleaning apparatus provided by the present invention is characterized by comprising: 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, wherein 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. The present invention has the benefit of obviating the need to build in a separate power source, such as a rechargeable battery, in the outer cleaning unit, for operating the sensor or the cleanser-supplying pump, by continuously supplying the needed power from the inner cleaning unit in real-time to the cleaning unit operating outside. |
