A household appliance has an air flow path extending from an air inlet to an air outlet with a fan and motor assembly in the air flow path. The fan and motor assembly comprises a motor drivingly connected to a rotating fan blade subassembly. The fan and motor assembly is adjustable between a first configuration in which the rotating fan blade subassembly provides a first level of air flow and a first level of suction and a second configuration in which the rotating fan blade subassembly provides a second level of air flow and a second level of suction wherein the first level of air flow is higher than the second level of air flow and the second level of suction is higher than the first level of suction.

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 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 robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

A touchless cleaning assembly for cleaning a room in a touch-less manner includes a cabinet is recessed into a wall of a room. A plurality of hose reels is positioned in the cabinet and each of the hose reels includes a hose that is drawable outwardly from the cabinet for spraying a fluid for cleaning surfaces in the room, for blowing air to dry the surfaces and to vacuum the surfaces. An air compressor is positioned within the cabinet to direct compressed air into a respective hose reel to dry the surfaces. A vacuum is positioned within the cabinet to supply vacuum pressure to the a respective hose reel for suctionally removing the fluid from a floor of the room.

A compressor has a rotor assembly having an impeller for generating an airflow through the compressor, a stator core assembly for causing rotation of the impeller, and a diffuser assembly for acting on the airflow generated by the impeller. The diffuser assembly has a first diffuser stage and a second diffuser stage. The first and second diffuser stages are separate components connected to one another by a fastener.

A portable vacuum cleaner comprises a housing including a storage space and a lid coupled to the housing. The lid is moveable between an open position, in which access to the storage space is provided, and a closed position, in which access to the storage space is blocked. The vacuum cleaner further comprises a handle coupled to the housing, a suction source supported in the housing, a debris collection chamber in fluid communication with the suction source, and a first battery receptacle on the housing. The first battery receptacle is configured to selectively receive a first battery pack that is configured to provide power to the suction source. The vacuum cleaner further comprises a hose port on the housing and in fluid communication with the suction source.

A street sweeper comprises a dirt container and a suction device. The suction device comprises a suction mouth, a suction channel and a suction fan. The suction fan generates a suction flow which leads into the dirt container. Furthermore, the street sweeper comprises a recycling system with a separating device. The separating device separates sucked-in dirty water from the dirt container into the recycling system. Furthermore, the street sweeper comprises a fresh-water tank in which fresh-water is stored. Furthermore, a cleaning device is provided by means of which at least a part of the recycling system can be cleaned. The fresh-water from the fresh-water tank is used for cleaning the recycling system.
