Disclosed herein is a robot cleaner driving method. The robot cleaner driving method comprises one or more setting steps of setting an imaginary space, including a space to be cleaned, and partitioning the imaginary space into one or more cells, one or more cleaning steps, which are assigned to the respective cells, of driving the robot cleaner to clean the assigned cells such that the directions of driving the robot cleaner are perpendicular to each other in some of the assigned cells, and one or more turning steps, which are performed after the respective cleaning steps or the respective setting steps are completed, of driving the robot cleaner to the next cell to be cleaned, at which one of the cleaning steps assigned to the cell is performed, such that the imaginary space is cleaned in the direction of a spiral on a per cell basis. According to the present invention, unnecessary driving operations of the robot cleaner are reduced, completion of the cleaning operation is predicted, and the cleaning efficiency of the robot cleaner is improved.
