A robot cleaner system is described including a docking station to form a docking area within a predetermined angle range of a front side thereof, to form docking guide areas which do not overlap each other on the left and right sides of the docking area, and to transmit a docking guide signal such that the docking guide areas are distinguished as a first docking guide area and a second docking guide area according to an arrival distance of the docking guide signal. The robot cleaner system also includes a robot cleaner to move to the docking area along a boundary between the first docking guide area and the second docking guide area when the docking guide signal is sensed and to move along the docking area so as to perform docking when reaching the docking area.

A cleaning apparatus including a main body, a dust collection unit detachably installed on the main body and provided with a plurality of inlets, through which foreign substances are introduced into the dust collection unit, and a connection hole, to which an external instrument is connected, a shutter to open and close one inlet, and a cap to open and close the connection hole. The shutter opens and closes the inlet in cooperation with one of whether or not the dust collection unit is attached to or detached from the main body and whether or not the connection hole is opened or closed.

Cleaning apparatus

A robot cleaner that travels straight through alignment of drive wheels to move the robot cleaner and a method of controlling travel of the same. Information related to a movement angle of the robot cleaner is detected from angle information of a caster wheel rotating depending upon a state of a floor, such as a carpet in a state in which texture of the carpet occurs in one direction, and, when the movement angle of the robot cleaner deviates due to slippages of the drive wheels, rates of rotation of the drive wheels are adjusted to correct the slippages of the drive wheels such that the robot cleaner easily travels straight.
