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.

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 hand vacuum cleaner has a cyclonic stage which comprises a stationary portion and an openable portion. The openable portion is rotatably mounted by a rotatable mount between a closed position in which a cyclone chamber is closed and an open position in which the cyclone chamber is open. The stationary portion comprises an upper portion of the first cyclonic stage and the openable portion comprises a lower portion of the first cyclonic stage. The rotatable mount is located at a rearward end of the openable portion.

A surface cleaning apparatus has a cyclone chamber and a dirt collection chamber exterior to the cyclone chamber. The cyclone chamber has a sidewall extending from a first end to an axially opposed second end. A dirt outlet communicating with the dirt collection chamber is provided in the sidewall at a location intermediate the first and second ends of the cyclone chamber.

A surface cleaning apparatus has a cyclone chamber. The cyclone chamber has an air inlet at a first end and an air outlet at an opposed end. A screen member extends from the air inlet to the air outlet at the opposed end.

A surface cleaning apparatus has a cyclone chamber and a dirt collection chamber. The cyclone chamber has a sidewall extending from a first end to an axially opposed second end. The dirt collection chamber has first and second axially opposed ends, the second end of the dirt collection chamber is located axially inwardly from the first end of the dirt collection chamber and the second end of the dirt collection chamber has a second end wall that is spaced axially inwardly from the second opposed end of the cyclone chamber.

A vacuum cleaner includes a canister defining a debris chamber, a power head mounted to a top of the canister, a motor connectable to a power source, and an impeller connected to the motor and operable to generate air flow upon operation of the motor. The power head includes a housing that includes an upper wall, a lower wall, a radial outer sidewall, and a volute that defines a volute chamber. A first portion of the upper wall and a first portion of the lower wall define an impeller chamber. A second portion of the upper wall, a second portion of the lower wall, and the sidewall define a flow passage that extends from the impeller chamber to the volute chamber. The volute is disposed radially outward from the flow passage and includes a lower wall that extends radially outward from the sidewall and around the perimeter of the sidewall.
