1. A cleaner comprising:
a suction part configured to introduce air to the cleaner;
a motor configured to generate a suction force for introducing the air through the suction part;
a motor housing that accommodates the motor;
a handle coupled to the motor housing;
cyclone parts coupled to a lower side of the motor housing and configured to separate dust from the air introduced through the suction part;
a dust bin that accommodates the cyclone parts and is separably coupled to a lower portion of the motor housing, the dust bin being configured to store the dust;
a filter disposed in the dust bin and configured to filter air having separated the dust through the cyclone parts; and
a compression part configured to compress the dust stored in the dust bin,
wherein the compression part comprises:
an operating part disposed in the motor housing and configured to move along an up-down direction in a space defined between an outer portion of the filter and an inner circumferential surface of the dust bin,
a manipulation part disposed outside the motor housing and configured to be manipulated to translate relative to the handle to cause the operating part to move in the up-down direction, and
a transmission part that is disposed in the motor housing and connects the operating part to the manipulation part,
wherein the dust bin is configured to be separated from the motor housing and become disconnected from the motor housing,
wherein the operating part and the transmission part are configured to remain in the motor housing based on the dust bin being separated from the motor housing, and
wherein the manipulation part is configured to remain outside the motor housing based on the dust bin being separated from the motor housing.
