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 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.

A vacuum cleaner includes a cleaner body, a suction hose mounted at a front surface of the cleaner body to suck in dust, moving wheels provided at both sides of the cleaner body, rotating to move the cleaner body and rotatably supporting the cleaner body, wheel motors connected to the moving wheels and rotating the moving wheels, a detecting unit provided in the cleaner body and sensing inclination of the cleaner body to determine whether the cleaner moves and stops, a plurality of detecting members provided at a front surface of the cleaner body and located at both sides of the suction hose to detect an obstacle, and a controller for controlling the wheel motors according to detected signals of the detecting unit and the obstacle detecting members.

A surface cleaning apparatus comprises a hand vacuum cleaner, a surface cleaning head and a rigid air flow conduit extending between the surface cleaning head and the hand vacuum cleaner. The hand vacuum cleaner comprises a main body and a removably mounted air treatment member. The air treatment member has an air inlet and the outlet end of the rigid air flow conduit is removably connectable in air flow communication with the air inlet.

A loading apparatus lowers or raises a dust or particulate collection container for ease of extraction and installation. This apparatus is disposed within a rigid frame structure capable of mounting to a wall or mobile device. A U-shaped member supports the dust collection container, the container typically being a cylindrical bucket or container with integral rim or handles. The U-shaped member orthogonally translates up into a first position and down into a second position with activation of a lever. The mechanics of the apparatus effects linear vertical travel of the dust collection container and when in a first position, mates the rim of the container onto a compliant gasket member disposed within the rigid frame structure, thus forming a vacuum-tight interface necessary for vacuum systems, in particular but not limited to, dust collection vacuum systems that utilize a cyclone dust separator.

A cleaner includes: a main body that has an opening; a suction motor that is disposed in the main body and generates suction force; and a filter unit that includes an exhaust filter for filtering air discharged from the suction motor, the filter unit being inserted into the main body through the opening and being separated from the main body, wherein when the filter unit is combined with the main body, a portion of the filter unit protrudes out of the main body, and a portion of the exhaust filter is positioned inside the main body and the other portion of the exhaust filter is positioned outside the main body.

A cyclone module for a vacuum cleaner includes a primary separator, a bulk collection chamber, at least one secondary separator, and a fines collection chamber. First and second doors are provided for closing debris outlets at the bottom ends of the bulk and fines collection chambers, respectively. The fines collection chamber is elevated within the bulk collection chamber, with the second door spaced above the first door.

A portable vacuum cleaner includes a housing and a filter assembly. The housing includes a dust collecting cylinder, a dust blocking cover and a main body. The dust collecting cylinder is opened to form an air inlet port and a mating port. The dust blocking cover is rotatably connected to the air inlet port of the dust collecting cylinder. The main body is detachably connected to the mating port of the dust collecting cylinder. A two-way locking structure is provided between the dust blocking cover and the main body. The two-way locking structure is adapted to lock or unlock the dust blocking cover and the main body simultaneously with the dust collecting cylinder, so that when the two-way locking structure is in a locked state, the dust blocking cover cannot open the air inlet port, while the dust collecting cylinder and the main body cannot be separated.
