Provided is a vacuum cleaner including a cleaner body having a motor generating a suction force; a dust container provided at a front end of the cleaner body and configured to collect dust sucked through a suction port; a cover member rotatably installed at an upper end of the cleaner body and opened and closed to selectively accommodate an upper portion of the dust container; a suction hose of which one side is connected to a suction portion suctioning the dust and the other side is connected to the cover member; a link assembly configured to connect between the cover member and the cleaner body; and a link assembly accommodating portion formed at one side of the cleaner body so that at least a part of the link assembly is inserted and configured to restrict the link assembly when the cover member is opened and thus to allow the cover member to be maintained in an opened state.

Provided is a vacuum cleaner including a cleaner body disposed at a position distant from the ground; moving wheels rotatably installed at both sides of the cleaner body and configured to rotatably support the cleaner body; a dust container installed at a front surface of the cleaner body located at a front of the moving wheels and configured to collect suctioned dust; and a suction hose connected to the front surface of the cleaner body and through which the dust is suctioned, wherein a center of gravity of the cleaner body is located at a rear side further than a vertical extension line of a rotating center of the moving wheels, and a rear end of the cleaner body becomes closer to the ground when travel of the vacuum cleaner is stopped.

Provided is a vacuum cleaner including a cleaner body; a moving wheel installed at both side surfaces of the cleaner body to be rotatable for travel of the cleaner body and configured to rotatably support the cleaner body; and a wheel motor assembly provided between an outer surface of the cleaner body and the moving wheel and configured to rotate the moving wheel for the travel of the cleaner body, wherein the wheel motor assembly is rotatably coupled to the moving wheel at a rear of a vertical extension line of a rotating center of the moving wheel.

A vacuum cleaner that includes: a cleaner body; a wheel; a dust container; a cover member that is configured to (i) rotate, about an axis that is outside of a plane of the cover member, between a first position and a second position and (ii) cover, based on the cover member being located at the first position or the second position, the first opening of the cleaner body and a portion of the dust container; a cover member coupling portion that couples the cover member to the cleaner body and that is configured to rotate about the second axis with the cover member; a suction nozzle that is coupled to the dust container and that is configured to guide dust into the dust container; and a display that is coupled to the cover member and that is configured to display operating information of the vacuum cleaner is disclosed.

Provided is a vacuum cleaner including a cleaner body; a dust container installed at the cleaner body and of which at least a part is exposed to an outside through a front surface of the cleaner body; a cover member installed to open and close a part of the cleaner body and configured to selectively accommodate an upper portion of the dust container; a suction hose of which one side is connected to a suction part for suctioning dust and the other side is connected to a front end of the cover member; a grip portion provided at the cover member and operated to open and close the cover member; and a locking assembly provided inside the cover member and disposed at both sides based on the suction part to be restricted in the cleaner body.

Provided is a vacuum cleaner including a cleaner body; a cover member installed at an upper portion of the cleaner body to be opened and closed and configured to form a part of a front surface and an upper surface of the cleaner body; a suction hose provided at a front surface of the cover member; a hole formed at the front surface of the cover member to be in communication with the suction hose; and an outlet port formed at a rear surface of the cleaner body to be located at a position lower than the hole, wherein air introduced through the hole is discharged to the outlet port via an inside of the cleaner body.

Provided is a vacuum cleaner including a cleaner body; a moving wheel provided at each of both side surfaces of the cleaner body, rotated for travelling of the vacuum cleaner and configured to support the cleaner body to be rotatable in normal and reverse directions; a wheel motor assembly connected to the moving wheel and configured to rotate the moving wheel for the travelling of the vacuum cleaner; a main motor provided inside the cleaner body, located at a rear side further than a vertical extension line of a rotating center of the moving wheel and driven to suction dust; and a battery provided inside the cleaner body, located at the rear side further than the vertical extension line of the rotating center of the moving wheel and configured to provide electric power to the main motor and the wheel motor assembly, wherein a center of gravity of the cleaner body is located at a rear of the vertical extension line of the rotating center of the moving wheel due to an arrangement of the main motor and the battery.
