a handle disposed at a rear portion of the cleaner at a position rearward of the dust separation unit; a battery housing disposed vertically under the handle; and a battery that is configured to be connectable upward to the battery housing from vertically underneath the battery housing. ### Claim 2 (depends on 1) The cleaner of claim 1, wherein the dust separation unit includes one or more cyclone units configured to generate cyclonic flow, and the battery is configured to be removable from the battery housing in a direction parallel with an axis of the cyclonic flow. ### Claim 3 (depends on 1) The cleaner of claim 1, wherein the battery includes a plurality of coupling portions that are horizontally spaced apart from each other and configured to be coupled to the battery housing. ### Claim 4 (depends on 3) The cleaner of claim 3, wherein the battery housing defines an opening at a bottom of the battery housing and is configured to receive the battery through the opening, and wherein a portion of the battery is exposed to an outside of the battery housing based on the battery being coupled to the battery housing by the plurality of coupling portions. ### Claim 5 (depends on 3) The cleaner of claim 3, wherein the plurality of coupling portions include a first coupling portion on a first side of the battery and a second coupling portion on a second side of the battery opposite the first coupling portion. ### Claim 6 (depends on 5) The cleaner of claim 5, wherein the first coupling portion and the second coupling portion are configured to be uncoupled from the battery housing by being moved toward each other. ### Claim 7 (depends on 5) The cleaner of claim 5, wherein the first coupling portion includes a first hook, and the battery housing includes a battery coupling portion that includes a locking rib configured to be coupled to the first hook. ### Claim 8 (depends on 7) The cleaner of claim 7, wherein the battery coupling portion defines a space configured to receive a portion of a user's hand or finger, and the first coupling portion is configured to be operated by the portion of the user's hand or finger inserted into the space. ### Claim 9 (depends on 5) The cleaner of claim 5, wherein the battery includes: battery cells; a frame configured to receive the battery cells; and an extension portion that extends rearward from a bottom rear portion of the cleaner, wherein the second coupling portion extends upward from the extension. ### Claim 10 (depends on 9) The cleaner of claim 9, wherein the second coupling portion includes a second hook, and an inner side of the battery housing defines a coupling groove that is configured to be coupled to the second hook. ### Claim 11 (depends on 5) The cleaner of claim 5, wherein the battery housing defines an exposing opening that is configured to expose the second coupling portion to an outside of the battery housing based on the second coupling portion being coupled to the battery housing. ### Claim 12 (depends on 1) The cleaner of claim 1, further comprising: a first main body terminal disposed outside the battery housing and configured to receive power to charge the battery inserted in the battery housing; and a second main body terminal disposed in the battery housing and configured to be electrically coupled to a terminal of the battery. ### Claim 13 (depends on 12) The cleaner of claim 12, further comprising a battery coupling portion configured to be detachably coupled to the battery, wherein the dust container includes a dust collection body and a body cover, the body cover being configured to open and close an interior of the dust collection body, wherein the battery coupling portion is disposed between the body cover and the battery, and wherein the first main body terminal is disposed in a groove defined on a bottom of the battery coupling portion. ### Claim 14 (depends on 12) The cleaner of claim 12, wherein the battery includes: battery cells; a frame configured to receive the battery cells; and a protrusion that protrudes upward from a top surface of the frame, the protrusion defining a terminal hole configured to receive the second main body terminal; wherein an interior of the battery housing includes a receiving portion that is configured to receive the protrusion of the battery, and wherein the second main body terminal is disposed in the receiving portion. ### Claim 15 (depends on 14) The cleaner of claim 14, wherein the protrusion is offset from a center of the frame. ### Claim 16 (depends on 1) The cleaner of claim 1, wherein the battery housing defines a heat dissipation hole that is configured to discharge heat generated by the battery. ### Claim 17 (depends on 1) The cleaner of claim 1, further comprising a bypass passage configured to guide air discharged from the suction motor toward the battery. ### Claim 18 (depends on 17) The cleaner of claim 17, further comprising a motor housing that is configured to receive the suction motor and that defines a bypass hole, wherein the bypass passage is defined by the bypass hole and an internal space of the handle. ### Claim 19 A cleaner comprising: a suction motor that is configured to generate suction force to thereby suction air; a dust separation unit that is disposed vertically under the suction motor and configured to separate dust from the suctioned air; a dust container that is configured to receive the dust separated by the dust separation unit; a handle that includes an operation unit configured to receive an input for turning on and turning off the suction motor; a battery housing disposed vertically under the handle; a battery detachably coupled to the battery housing; a first main body terminal configured to receive power to charge the battery inserted in the battery housing; and a second main body terminal configured to be electrically coupled to the battery inserted in the battery housing. ### Claim 20 A cleaner comprising: a suction motor that is configured to generate suction force to thereby suction air; one or more cyclone units that are configured to generate cyclonic flow to thereby separate dust from the suctioned air; a dust container that is configured to receive the dust separated by the one or more cyclone units; a battery housing disposed at a rear portion of the cleaner at a position rearward of the dust container; and a battery detachably inserted in the battery housing and configured to supply power to the suction motor, wherein the battery housing is configured to receive the battery along a direction parallel with an axis of the cyclonic flow.
