1. A method of controlling a movement of a window cleaning apparatus that is attached and moved on a window, the method comprising:
- detecting, by a control device, an initial attachment position of the window cleaning apparatus, the detecting comprising determining whether the initial attachment position is positioned on a first side of the window or a second side opposite to the first side of the window; and
moving, by the control device, the window cleaning apparatus to a detachment position after completion of the cleaning the window, the detachment position being provided at one of an end of the first side and an end of the second side of the window corresponding to the detected initial attachment position,wherein the detecting the initial attachment position comprises;
moving the window cleaning apparatus vertically from the initial attachment position to a first position, the first position corresponding to a top end of the window;
moving the window cleaning apparatus horizontally at the top end of the window from the first position to a second position by a first distance, the second position corresponding to the end of the first side of the window;
moving the window cleaning apparatus horizontally from the second position to a third position by a second distance, the third position corresponding to the end of the second side at the top end of the window; and
determining the initial attachment position based on a result of comparing the first and second distances.

12. A method of controlling a movement of a window cleaning apparatus that is attached and moved on a window, the method comprising:
-
detecting, by a control device, an initial attachment position of the window cleaning apparatus, the detecting comprising determining whether the initial attachment position is positioned on a first side of the window or a second side opposite to the side side of the window; and moving, by the control device, the window cleaning apparatus to a detachment position after completion of the cleaning the window, the detachment position being provided at one of an end of the first side and an end of the second side of the window corresponding to the detected initial attachment position, wherein the detecting the initial attachment position comprises; moving the window cleaning apparatus horizontally from the initial attachment position to the end of the second side of the window by a third distance; moving the window cleaning apparatus vertically to a top end of the window after moving the window cleaning apparatus to the end of the second side of the window; moving the window cleaning apparatus horizontally at the top end toward the end of the first side from the end of the second side of the window by a fourth distance; and determining that the initial attachment position is at the first side on the window, if the third distance is larger than a half of the fourth distance. - View Dependent Claims (13)

14. A window cleaning apparatus that is attached and moved on a window, the window cleaning apparatus comprising:
-
a first cleaning unit; and a second cleaning unit, the first and second cleaning unit being respectively attached to an inner side and an outer side of a window by a magnetic force and configured to move on the window, wherein at least one of the first and second cleaning units comprises a control unit configured to detect an initial attachment position of one of the first and second cleaning units, configured to determine whether the initial attachment position is positioned on a first side of the window or a second side opposite to the first side of the window and configured to move the window cleaning apparatus to a detachment position, the detachment position being provided at one of an end of the first side and an end of the second side of the window in the horizontal direction corresponding to the detected initial attachment position, after completion of cleaning the window, wherein the control unit is configured to detect the initial attachment position of the one of the first and second cleaning units by controlling the one of the first and second cleaning units to move vertically from the initial attachment position to a first position, the first position corresponding to a top end of the window to move the window cleaning apparatus horizontally at the top end of the window from the first position to a second position by a first distance, the second position corresponding to the end of the first side of the window, to move the window cleaning apparatus horizontally from the second position to a third position by a second distance, the third position corresponding to the end of the second side at the top end of the window and to determine the initial attachment position based on a result of comparison between the first and second distances. - View Dependent Claims (15, 16)
