Provided is a vacuum cleaner including a base configured to form a lower surface of a cleaner body; moving wheels provided at both side surfaces of the cleaner body and rotated for travel of the vacuum cleaner and also configured to support the cleaner body to be rotated in normal and reverse directions; and a dust container installed at a front of the moving wheels and configured to collect suctioned dust, wherein the base includes a center portion; a first half portion configured to extend to be inclined upward from a front end of the center portion; and a second half portion configured to extend to be inclined upward from a rear end of the center portion, and a rotating center of the moving wheels is located between the first half portion and the second half portion.

A vacuum cleaner that includes: a suction hose; and a cleaner main body including: a main body portion, a suction motor that is configured to generate suction force, a dust container that includes (i) a storage space to collect dust and (ii) a suction port through which dust is collected from the suction hose into the storage space, and 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, (ii) that covers, based on the cover member being located at the first position, at least a portion of the dust container, and (iii) that includes a coupling unit that couples the suction hose to the suction port, wherein, based on the cover member being located at the first position, the coupling unit aligns with the suction port is disclosed.

A vacuum cleaner includes a cleaner body including a suction motor for generating suction force and a suction part communicating with the cleaner body to suck in air and dust. The cleaner body includes a main body, wheels for moving the main body, and a battery detachably provided at a back side of the main body to supply power to the main body.

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; a cover member provided at an upper portion of the cleaner body to be opened and closed; a suction hose installed at a front surface of the cover member and configured to suction dust; moving wheels provided on both side surfaces of the cleaner body; a wheel motor assembly connected to the moving wheels and configured to rotate the moving wheels for travel; a plurality of obstacle detecting members disposed at one side of a front of the cover member and configured to detect an obstacle located at a front and/or a side of the cleaner body; and a PCB configured to control an operation of the wheel motor assembly according to a detected signal of the obstacle detecting member.

A vacuum cleaner includes: a cleaner body including a battery chamber; a motor provided in the cleaner body to provide suction force; a battery detachably mounted in the battery chamber to provide electric power to the motor; a battery cover rotatably mounted in the cleaner body to open and close the battery chamber; and a charging stand on which the cleaner body is held and which includes an opening prevention rib located on a rotation path of the battery cover in a state in which the cleaner body is held on the opening prevention rib and preventing opening of the battery cover.
