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 blower includes an impeller rotatable about a central axis extending in a vertical direction, a motor on a lower side of the impeller that rotates the impeller about the central axis, and a duct including an airflow passage in an inner space, a suction port through which a fluid flows in the inner space, and an air outlet through which the fluid is discharged from the inner space, the impeller being accommodated in the duct. The impeller includes blades arranged in a circumferential direction, an annular shroud that connects upper portions of the blades and includes an opening opposing the suction port in an axial direction, and a base plate that connects lower portions of the blades and extends in a radial direction. The duct includes a cover covering at least a portion of the blade and an upper portion of the shroud. An inner diameter of the shroud is equal to or larger than an outer diameter of the base plate. The cover includes a projection that projects axially downward from a bottom surface of the cover and is on a radial interior of an inner circumferential surface of the shroud.

A vacuum cleaner comprises a housing and a motor fan assembly arranged to generate an air flow. A detachable dirt container is mountable to the housing; the dirt container having a dirty air inlet in fluid communication with the motor fan assembly. A filter is for separating dirt from the air flow, the filter being mounted between the dirt container and the motor fan assembly. The housing comprises at least one air outlet for exhausting clean air from the motor fan assembly. Wherein the detachable dirt container comprises at least one projecting lip arranged to overlap the at least one air outlet when the detachable dirt container is mounted on the housing and direct the air flow away from the dirty air inlet.

A mobile vacuum cleaning device comprises a housing (1) containing a vacuum cleaner and having an aperture (5) to allow a suction hose (6) to be led therethrough and coupled to an intake air inlet of the vacuum cleaner and an opening (7) to direct air exhausted by the exhaust air outlet of the vacuum cleaner out of the housing. The housing has members (11) making it movable.

A surface cleaning apparatus is described including a housing supporting a suction source including a motor with an axle which rotates a fan and a dirt collection container. The motor is positioned within a motor chamber and the motor chamber is positioned within a further chamber, and there being an opening in the motor chamber for permitting exhaust air to pass therefrom to the further chamber. The housing includes an exhaust outlet and wherein air from the motor chamber passes to the exhaust outlet around opposing sides of the motor chamber. In an alternative embodiment air from the motor chamber passes to the exhaust outlet through an air diffusing member.
