METHOD FOR CONTROLLING WINDOW CLEANING APPARATUS

摘要

According to one embodiment of the present invention, in the cleaning units that are attached respectively to the inner and outer surfaces of a window and move on the inner and outer surfaces by means of magnetic force, the magnetic force working between first and second cleaning units is initialized during an initial operation, thereby holding the magnetic force constant. Furthermore, according to another embodiment of the present invention, in the cleaning units that are attached respectively to the inner and outer surfaces of a window and move on the inner and outer surfaces by means of magnetic force, first and second cleaning units that can be interlock with each other as a set are automatically set during an initial operation from among a plurality of first and second cleaning units, thus increasing user convenience.
