Methods and apparatus for cleaning a surface with a cleaning device having a body with a handle, a connector, and one or more cleaning heads that are removably attached to the cleaning device. Each cleaning head include a lower surface arranged to contact a surface to be cleaned and a dirt collection chamber permanently attached to the cleaning head. The cleaning head may include a support structure to support the dirt collection chamber and a cleaning sheet. The cleaning head also may include a suction nozzle. At least a portion of the dirt collection chamber may be made of a filter material.

A vacuum cleaner includes a suction inlet, a suction source configured to generate an airflow through the suction inlet to draw debris with the airflow through the suction inlet, and a separator assembly. The separator assembly includes a housing having an air inlet and an air outlet, a debris collection chamber within the housing, and an inner chamber formed within a shroud that defines a cyclone axis and has a perforated portion. The inner chamber has a first end and a second end. The first end has a tangential inlet. The second end is open toward the debris collection chamber. An outflow passageway is outside of the shroud and in fluid communication with the air outlet and a filter is in fluid communication with the outflow passageway. The first end of the inner chamber is positioned between the air outlet and the second end of the inner chamber.

A hand vacuum cleaner having an air treatment member positioned in the air flow passage upstream from a suction motor and comprising a dirt chamber having an openable door, wherein an openable lock securing the door in a closed position is provided. A hand vacuum cleaner having a cyclonic stage and a suction motor, wherein the cyclone unit is mounted to a motor housing wherein a projection of the motor axis extends through the cyclonic stage is also provided.

A vacuum cleaner (100) is provided. The vacuum cleaner (100) includes a hand-held device (400), and the hand-held device includes: a housing (401); a dust cup (402) disposed in the housing (401) and having a dust outlet in a bottom thereof; and an ash pouring plate (405) disposed at a bottom of the housing (401. The ash pouring plate (405) is configured to be movable between an open position for opening the dust outlet and a closed position for closing the dust outlet.

An evacuation station includes a base and a canister removably attached to the base. The base includes a ramp having an inclined surface for receiving a robotic cleaner having a debris bin. The ramp defines an evacuation intake opening arranged to pneumatically interface with the debris bin. The base also includes a first conduit portion pneumatically connected to the evacuation intake opening, an air mover having an inlet and an exhaust, and a particle filter pneumatically the exhaust of the air mover. The canister includes a second conduit portion arranged to pneumatically interface with the first conduit portion to form a pneumatic debris intake conduit, an exhaust conduit arranged to pneumatically connect to the inlet of the air mover when the canister is attached to the base, and a separator in pneumatic communication with the second conduit portion.

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 hand vacuum cleaner has a pre-motor filter, a suction motor and a post motor filter that are arranged linearly.

Methods and apparatus for cleaning a surface with a cleaning device having a body with a handle, a connector, and one or more cleaning heads that are removably attached to the cleaning device. Each cleaning head include a lower surface arranged to contact a surface to be cleaned and a dirt collection chamber permanently attached to the cleaning head. The cleaning head may include a support structure to support the dirt collection chamber and a cleaning sheet. The cleaning head also may include a suction nozzle. At least a portion of the dirt collection chamber may be made of a filter material.

A docking station for a robotic cleaner may include a base, a docking station dust cup removably coupled to the base, a latch actuatable between a retaining position and a release position, and a release system configured to actuate the latch between the retaining and release positions. The docking station dust cup may be removable from the base in response to a pivotal movement of the docking station dust cup relative to the base about a pivot point. The latch may be horizontally spaced apart from the pivot point, wherein, when the latch is in the retaining position, pivotal movement of the docking station dust cup is substantially prevented.

Ae multifunction vacuum cleaner includes a container body, which houses a suction unit of air flows from the outside; a filter of the air flows sucked from the outside; an accumulation tank of materials sucked from the outside and filtered by the filter; and a steam production unit and a system sending steam to the outside of the container body.
