A surface cleaning apparatus has a cyclone including first and second opposed ends, a cyclone axis of rotation that intersects the first and second ends, an air inlet, an air outlet provided at the second end, and a cyclone sidewall extending between the first and second ends. The air outlet includes an outlet air permeable portion extending axially inwardly into the cyclone from the second end. The porous member has an axially inner end and an axial outer end located at the second end and the axial outer end is positioned at the cyclone sidewall.

A vacuum cleaner includes an upright handle assembly, a foot assembly adapted to be moved along a surface to be cleaned and having a suction nozzle, a multi-axis joint swivelably mounting the upright handle assembly to the foot assembly and defining a first axis about which the upright handle assembly twists relative to the foot assembly and a second axis about which the upright handle assembly pivot relative to the foot assembly, and a detachable vacuum module supported on the upright handle assembly by the module platform.

A reconfigurable upright vacuum cleaner has a portable surface cleaning unit removably mounted to an upper portion. The portable surface cleaning unit has a suction motor and an air treatment member. The air treatment member is removably mounted to the portable surface cleaning unit and secured in position by an air treatment member lock. The portable surface cleaning unit is secured in position by a portable surface cleaning unit lock. When the portable surface cleaning unit is mounted to the upper portion and the upper portion is in the storage position, the portable surface cleaning unit actuator is provided on an upper end of the portable surface cleaning unit and the air treatment member release actuator is provided on an upper end of the air treatment member.

A surface cleaning apparatus has a surface cleaning head having a pivoting connector, an upper end of the pivoting connector providing an air outlet of the surface cleaning head. A support consisting of an upflow duct is pivotally mounted to the surface cleaning head by the pivoting connector. A surface cleaning unit is vertically removably mounted to an upper end of the support. The surface cleaning unit comprises a cyclone unit, a pre-motor filter, a suction motor and flexible hose.

A vacuum cleaner has an upright support structure pivotally mounted to a cleaning head. A portable surface cleaning unit is removably mounted to the upright support structure. The portable surface cleaning unit has a cyclone chamber, a dirt collection chamber exterior to the cyclone chamber and a suction motor. When the portable surface cleaning unit is mounted to the upright support structure and the upright support structure extends upwardly from the cleaning head, the upper end wall of the dirt collection chamber and the cyclone chamber end wall are an openable upper wall of the portable surface cleaning unit.

A hand vacuum cleaner has an air flow path extending from a dirty air inlet to a clean air outlet. An air treatment member and suction motor are positioned in the air flow path. The air treatment member is provided at the front end of the hand vacuum cleaner and has an air outlet provided at the rear end of the air treatment member. A pre-motor filter housing is provided rearward of the air treatment member. A pistol grip handle has an upper end that is mounted to the pre-motor filter housing.

Disclosed are devices, systems, and methods for modular vacuum cleaners. An example vacuum cleaner system includes a canister vacuum cleaner device and a robotic vacuum cleaner device, where the robotic vacuum cleaner is removably coupled to or is digitally communicable with the canister vacuum cleaner device. The canister vacuum cleaner device comprises a canister to collect debris, a vertical hollow structure that located towards a rear of the canister and coupled to the canister, a flexible extendable hose, and a housing located below the canister, wherein the housing includes a retractable electrical cord. The robotic vacuum cleaner device comprises: a storage area to collect debris, a battery, a plurality of wheels that are removably coupled to one or more motors, and a lever or a valve structured to direct debris either to the storage area or to the canister.

The present disclosure relates to a cleaner system including: a cleaner; a cleaner station; and an imaginary plane including an imaginary suction flow path through line penetrating a suction flow path in a longitudinal direction and an imaginary suction motor axis defined by extending a rotation axis of a suction motor, in which when the cleaner is coupled to the cleaner station, the plane penetrates at least a part of the cleaner station, such that a center of gravity of the cleaner is disposed to pass through a space for maintaining balance of the station, and as a result, it is possible to stably support the cleaner and the station while preventing the cleaner and the station from falling down.

A cleaner includes: a motor housing in which a motor is provided to generate a suction force for drawing in air; a handle part coupled to the motor housing; a dust bin separably coupled to a lower portion of the motor housing and configured to store therein sucked dust; a cyclone part positioned in the dust bin and configured to separate dust from the air drawn in through a suction part; and a compression part configured to compress the dust in the dust bin, in which the dust bin is separated downward from the motor housing, and a user may easily wash the dust bin.

Hand held vacuum cleaning apparatus (100) includes an elongate housing (122) which is cylindrical in shape. The housing (122) defines an inlet opening (108), an interior (124) and an exhaust opening (118). The housing (122) further defines, within the interior (124), a receptacle receiving chamber (112) in which, in use, a removable dust retaining receptacle (115) is located. The receptacle receiving chamber (112) is substantially circular in cross section and comprises substantially the whole of the diameter of the interior (124) in cross section. The apparatus (100) includes a flow inducer (117) located in the interior (124). In use, the flow inducer (117) induces air flow from the inlet opening (108), through the receptacle (115) in the chamber (112), through the flow inducer (117) to the exhaust opening (118).
