a suction motor disposed above the longitudinal axis and configured to generate suction force to thereby suction air through the suction unit; a discharge cover disposed above the longitudinal axis; a dust separation unit configured to separate dust from the suctioned air; a dust container that is configured to store the dust separated from the suctioned air and that surrounds an outer circumference of the dust separation unit; a battery disposed below the longitudinal axis and disposed behind the dust container, the battery being configured to supply power to the suction motor; and a handle that is disposed above the battery and extends forward toward the suction motor, wherein the longitudinal axis passes through the handle, and wherein a rotational axis of the suction motor passes through the discharge cover and the dust separation unit. ### Claim 2 (depends on 1) The handy cleaner of claim 1, wherein an extending direction of the handle crosses the longitudinal axis obliquely. ### Claim 3 (depends on 2) The handy cleaner of claim 2, wherein the handle includes an operation unit extending in the extension direction crossing the longitudinal axis obliquely. ### Claim 4 (depends on 3) The handy cleaner of claim 3, wherein the extension direction of the handle and the extension direction of the operation unit define different angles with respect to the longitudinal axis. ### Claim 5 (depends on 1) The handy cleaner of claim 1, wherein the longitudinal axis intersects an extension direction of the handle. ### Claim 6 (depends on 1) The handy cleaner of claim 1, wherein the battery is positioned behind the suction motor. ### Claim 7 (depends on 6) The handy cleaner of claim 6, wherein a center of the suction motor and a center of the battery are positioned on opposite sides with respect to a vertical axis extending perpendicularly to the longitudinal axis from a front end of the battery. ### Claim 8 (depends on 1) The handy cleaner of claim 1, wherein the suction motor, the dust separation unit, and the dust container are sequentially arranged and overlap each other along the rotational axis of the suction motor. ### Claim 9 (depends on 1) The handy cleaner of claim 1, wherein the discharge cover includes air exits arranged in a circumferential direction with respect to the rotational axis of the suction motor. ### Claim 10 (depends on 9) The handy cleaner of claim 9, wherein the discharge cover is disposed in front of the handle, and wherein the air exits are configured to guide air passing through the suction motor to be discharged to an outside of the handy cleaner. ### Claim 11 (depends on 10) The handy cleaner of claim 10, wherein the rotational axis of the suction motor obliquely crosses an extension direction of the handle. ### Claim 12 (depends on 9) The handy cleaner of claim 9, wherein the air exits are disposed above the longitudinal axis. ### Claim 13 (depends on 1) The handy cleaner of claim 1, further comprising: a pre-filter that is disposed above the longitudinal axis and extends in a circumferential direction about the rotational axis of the suction motor. ### Claim 14 (depends on 13) The handy cleaner of claim 13, wherein the discharge cover further includes: a secondary filter arranged to correspond to air exits and configured to filter air discharged from the suction motor. ### Claim 15 (depends on 14) The handy cleaner of claim 14, wherein the secondary filter is positioned radially outside the pre-filter and around the rotational axis of the suction motor. ### Claim 16 (depends on 14) The handy cleaner of claim 14, wherein the secondary filter is positioned above the longitudinal axis. ### Claim 17 (depends on 16) The handy cleaner of claim 16, wherein the battery is detachably provided in a direction parallel to the rotational axis of the suction motor. ### Claim 18 (depends on 1) The handy cleaner of claim 1, wherein a portion of the dust container is configured to open in a direction of the rotational axis of the suction motor. ### Claim 19 (depends on 1) The handy cleaner of claim 1, wherein the dust separation unit includes: a first cyclone unit configured to separate dust from the air suctioned by the suction unit; and a second cyclone unit configured to separate dust from the air having passed through the first cyclone unit. ### Claim 20 (depends on 1) The handy cleaner of claim 1, wherein the battery is detachably provided in a direction away from the handle.
