A cleaner includes: a main body that forms an external shape; a dust container that is separably combined with the main body and stores dust separated from air; a dust container cover that is configured to open and close the dust container; a handle unit that is disposed behind the dust container; and an operating member that is configured to provide operation force to the dust container cover by moving in a first direction and to release a holding mechanism for preventing separation of the dust container from the main body by moving in a second direction opposite to the first direction.

A portable surface cleaning apparatus has a main body and air treatment member assembly is removably mounted to the main body. The air treatment member assembly air outlet and/or the suction motor inlet end is provided at the lower end of the air treatment member assembly when the surface cleaning apparatus is located on a floor and a pre-motor filter underlies the air treatment member assembly and/or the suction motor.

A vacuum cleaner that includes a suction source configured to generate a suction airflow, a dirt collector in fluid communication with the suction source and configured to separate debris from the suction airflow and the dirt collector is configured to store the debris separated from the suction airflow. The vacuum further includes an infrared sensor operable to output a signal corresponding to a distance to an amount of debris stored in the dirt collector, a controller that receives the signal, and the controller is operable to determine a fill level stored in the dirt collector based on the signal. A visual display displays the fill level stored in the dirt collector.

The hand-held cleaner includes a body, and a cyclone dust collecting apparatus detachably mounted in the body. The cyclone dust collecting apparatus includes a pre-motor filter unit having a filter grill and a filter member, a dust collecting bin having one end to which the pre-motor filter unit is coupled and the other end opposite to the one end in which an cyclone inlet is formed, and a cyclone bin disposed in the dust collecting bin and having a spiral flow path-guide member integrally formed therein. A moving path of air drawn into the cyclone inlet is maintained in the same direction until the air is discharged through the pre-motor filter unit via the cyclone bin.

A cyclone separation device includes a cyclone chamber for separating dirt from incoming air, a dirt collecting chamber arranged adjacent to the cyclone chamber for collecting dirt particles separated from air, and a dirt duct between the cyclone chamber and the dirt collecting chamber for allowing dirt particles to exit the cyclone chamber into the dirt collecting chamber. To reduce the generation of noise-generating air vortices, the dirt duct has an edge protruding into a direction at an angle to the dirt duct at an exit ridge of the cyclone chamber that is first encountered by the air rotating in the cyclone chamber. Preferably, the edge is formed by a tangential extension of a wall of the cyclone chamber. A vacuum cleaner advantageously includes such a cyclone separation device.

A surface cleaning apparatus is disclosed having a forward portion and a rearward portion. The forward portion has a dirty air inlet, a front side, a rear side and a forward bridging section, the forward bridging section having a rearwardly extending air flow passage that is downstream from the dirty air inlet. The rearward portion positioned rearward of the forward portion, the rearward portion comprising a front side, a rearward side, a rearward bridging section, a lower planar surface, an upper surface and an up flow duct, the rearward bridging section being spaced rearward of the front side of the rearward portion. The rear side of the forward portion is spaced from and faces the front side of the rearward portion and the forward bridging section is connected to the rearward bridging section.

A hand vacuum cleaner has an air treatment member chamber positioned in the air flow path downstream of a dirty air inlet, an on board energy storage member positioned in the air flow path downstream from the air treatment member chamber whereby air passing through the air flow path cools the on board energy storage member, and a suction motor positioned in the air flow path downstream of the on board energy storage member and upstream of the clean air outlet. The air treatment member, onboard energy storage member, and suction motor can be arranged linearly with the longitudinal axis of the air treatment member extending through both the onboard energy storage member and the suction motor.

A cleaner is disclosed. The cleaner includes: a housing having an introduction opening through which air is introduced; a filtering unit configured to be mounted in an inner space of the housing, and defining a dust collection space between the filtering unit and an inner surface of the housing; and a cleaning unit configured to surround the filtering unit, and configured to be raised and lowered inside the dust collection space along with a manipulation unit, wherein, when the cleaning unit is in an initial position, at least a portion of the cleaning unit is connected to an air introduction path extending from the introduction opening to form a guide flow path to guide a flow of introduced air.

A cordless wet and dry stick vacuum cleaner system has a portable power module, which includes an airflow generator, a battery, and control circuitry. This may be used with either a wet dirt management system and a wet vacuum nozzle or it may be used with a dry dirt management system and a dry vacuum nozzle. The shared power module enables power savings, whereas the other parts remain optimized for their specific function.
