wherein, based on the cover member being located at the first position, the coupling unit aligns with the suction port.

2. The vacuum cleaner of claim 1, wherein the coupling unit includes:

an inlet portion through which dust is introduced from the suction hose, and

an outlet portion from which dust is discharged into the storage space of the dust container, and

wherein, based on the cover member being located at the first position, the outlet portion of the coupling unit is coupled to the suction port.

3. The vacuum cleaner of claim 2, further comprising:

a sealing member (i) that is configured to couple the outlet portion of the coupling unit to the suction port and (ii) that is configured to block dust from being scattered outside of the coupling unit or the suction port.

4. The vacuum cleaner of claim 1, wherein, based on the cover member being located at the first position, the coupling unit aligns with the suction hose.

5. The vacuum cleaner of claim 1, wherein the suction hose includes:

a fitting portion that is located at a first end of the suction hose, and

wherein at least a portion of the fitting portion is configured to insert into the coupling unit.

6. The vacuum cleaner of claim 5, wherein the coupling unit includes:

a stepped portion on an inside surface of the coupling unit, the stepped portion being configured to (i) hold at least the portion of the fitting portion and (ii) block at least the portion of the fitting portion from being inserted beyond the stepped portion.

7. The vacuum cleaner of claim 1, wherein the dust container includes:

a side surface where, in a state in which the cover member covers at least the portion of the dust container, a first portion of the side surface is exposed to an exterior area of the vacuum cleaner, and

wherein an interior area of the dust container is viewable from the exterior area of the vacuum cleaner through the first portion of the side surface.

8. The vacuum cleaner of claim 1, further comprising:

a connecting member that couples the cover member to the main body portion and that is configured to rotate about the axis with the cover member.

9. The vacuum cleaner of claim 1, wherein the cover member includes:

a grip portion that is configured to be gripped by a user to move the cover member between the first position and the second position.

10. The vacuum cleaner of claim 1, wherein the main body portion includes:

a seat portion that accommodates the dust container.

11. A vacuum cleaner, comprising:

a suction hose that is configured to guide dust; and

a cleaner main body that is coupled to the suction hose and that includes;

a suction motor that is configured to generate suction force,

a dust container that includes a storage space to collect dust,

a suction port that couples the suction hose to the dust container and through which dust is collected from the suction hose into the dust container, and

a cover member that is coupled to the dust container and that includes;

a coupling unit that couples the suction hose to the dust container and that is configured to guide, in a horizontal direction relative to a floor, dust from the suction hose into the storage space of the dust container.

12. A vacuum cleaner, comprising:

a suction hose that is configured to guide dust; and

a cleaner main body that is coupled to the suction hose and that includes;

a suction motor that is configured to generate suction force,

a dust container that includes;

a suction port through which dust is collected from the suction hose into the dust container and that is located on a top surface of the dust container relative to ground, and

a cover member that is coupled to the dust container and that includes;

a coupling unit including a first end and a second end, the first end being coupled to the suction hose and the second end being coupled to the suction port.

13. A vacuum cleaner, comprising:

a suction hose that is configured to guide dust;

a cleaner main body that is coupled to the suction hose and that includes a suction motor that is configured to generate suction force;

a dust container that is located adjacent to the cleaner main body and that includes (i) a side surface, a first portion of the side surface being exposed to an exterior area of the vacuum cleaner, (ii) a storage space to collect dust, and (iii) an opening to the storage space;

a cover member (i) that is configured to rotate, about an axis that is outside of a plane of the cover member, between a first position and a second position and (ii) that covers, based on the cover member being located at the first position, at least a portion of the dust container;
