1. A cleaning module comprising:
a housing communicating with a suction port of a main body of a cleaner, and comprising a suction space configured to be exposed to a bottom surface;
a first hole located on a first side surface of the housing perpendicular to a cleaning direction and configured to expose an inside of the housing; and
a first opening/closing device including a first shielding member configured to enable communication with the suction space and an exterior of the first side surface by selectively opening/closing the first hole and a second shielding member configured to selectively open/close a first space between a second side surface of the housing perpendicular to the cleaning direction and a central region of the housing;
a second hole located on the second side surface perpendicular to the cleaning direction, and configured to expose the inside of the housing with respect to the suction space; and
a second opening/closing device including a third shielding member configured to enable communication with the suction space and an exterior of the second side surface by selectively opening/closing the second hole and a fourth shielding member configured to selectively open/close a second space between the first side surface of the housing and the central region of the housing,
wherein, when the first opening/closing device is in a first position, the first shielding member opens the first hole and the second shielding member closes the first space, and when the first opening/closing device is in a second position, the first shielding member closes the first hole and the second shielding member opens the first space,
wherein, when the second opening/closing device is in a first position, the third shielding member opens the second hole and the fourth shielding member closes the second space, and when the second opening/closing device is in a second position, the third shielding member closes the second hole and the fourth shielding member opens the second space, and
wherein the first opening/closing device and the second opening/closing device operate independently.
