Abstract: Disclosed are an autonomous mobile cleaner, and a method for moving the same. A user's intention may be estimated based on a size and a direction of a tensile strength applied to the air pipe, and a cleaner body may move according to the user's intention. This can allow the cleaner to autonomously move. Besides, the autonomous mobile cleaner can always and precisely detect a user's operation without having interference with obstacles, using a displacement of the air pipe. Further, the fabrication costs can be reduced and displacements in all directions can be calculated, by using a hall sensor and a magnet member. Further, a user's efforts to operate the cleaner can be minimized, and can be prevented damages of the air pipe, a connection part between the air pipe and the cleaner body, etc. due to an excessive force.
