A cleaner is provided. The cleaner includes a housing, a filtering member provided to form a dust collecting chamber inside the housing, and a main body configured to be moved relative to the housing. The main body includes a dirt removal member configured to be moved on the dust collecting chamber, an opening and closing device configured to open and close the dust collecting chamber and provided to interlock with the dirt removal member, and a connecting frame configured to connect the dirt removal member and the opening and closing device, the connecting frame including a guide rib provided to prevent rubbish, which is contained in air flowing into the dust collecting chamber, from rotating in the dust collecting chamber.

An evacuation station for collecting debris from a cleaning robot includes a controller configured to execute instructions to perform one or more operations. The one or more operations includes initiating an evacuation operation such that an air mover draws air containing debris from the cleaning robot, through an intake of the evacuation station, and through a canister of the evacuation station and such that a receptacle received by the evacuation station receives at least a portion of the debris drawn from the cleaning robot. The one or more operations includes ceasing the evacuation operation in response to a pressure value being within a range. The pressure value is determined based at least in part on data indicative of an air pressure, and the range is set based at least in part on a number of evacuation operations initiated before the evacuation operation.

A system comprising a vacuum cleaner and an apparatus for receiving dirt from a dirt collection region of the vacuum cleaner. The apparatus has an air flow passage from an inlet port to a clean air outlet, wherein the dirt collection region of the vacuum cleaner is positionable in air flow communication with the inlet port. In an emptying mode of operation, a motor and fan assembly of the system produces a flow of air that conveys dirt from the dirt collection region of the vacuum cleaner to the air treatment member of the apparatus. The vacuum cleaner is docked with the apparatus by a user moving the dirt collection region in a downward direction to a position in which, during the emptying mode of operation, the flow of air conveys the dirt from the dirt collection region of the vacuum cleaner downwardly to the air treatment member of the apparatus.

A hand vacuum cleaner has an air flow path extending from a dirty air inlet provided at a front end of the hand vacuum cleaner to a clean air outlet, a main body housing a suction motor, and an air treatment member that is moveably mounted to the main body between an operating position and an emptying position. The hand vacuum cleaner also includes a post-motor filter housing, wherein a post-motor-filter is removably receivable in the post-motor filter housing, and wherein moving the air treatment member to the emptying position enables access to the post-motor-filter.

A vacuum cleaner includes an air treatment or debris removable assembly with a multi-layer filtration stage. The multi-layer filtration stage can include an outer mesh screen, a louvered exhaust grill, and a multi-layer filter. Optionally, an inner perforated exhaust grill is also provided. The debris removable assembly can further include a cyclonic filtration stage.

A cleaner includes a suction unit guiding air and dust, a main body including a first cyclone unit separating the air and the dust, which are suctioned through the suction unit, from each other and a second cyclone unit separating the dust from the air discharged from the first cyclone unit, and a guide unit disposed in the main body to partition a first dust storage part, in which the dust separated in the first cyclone unit is stored, and a second dust storage part, in which the dust separated in the second cyclone unit is stored, from each other. The guide unit is separably coupled to the main body, and when the guide unit is separated from the main body, a dust discharge part of the second cyclone unit is exposed to the outside.

A base station for connecting a cleaning device and a method for operating a cleaning system with a cleaning device and such a base station are proposed, wherein the room air is conditioned by means of the base station and/or the quality of the room air is measured by means of the base station.

A surface cleaning apparatus comprises an air treatment chamber having a first end comprising a first end wall, an axially spaced apart second end comprising a second end wall, a sidewall extending between the first and second end walls, an air treatment chamber air inlet and an air treatment chamber air outlet provided at the second end. A dirt collection region, which is contiguous with the air treatment chamber, is positioned axially from the first and second end walls and is closer to the second end wall than the first end wall.

A hand vacuum cleaner has a cyclonic stage comprising an openable front wall provided at the front end of the cyclonic stage. A pre-motor filter is positioned in the air flow passage downstream from the cyclone air outlet and rearward of the cyclone sidewall. The pre-motor filter has a diameter in a direction transverse to the cyclone axis that is larger than a diameter of the cyclone air outlet in the direction transverse to the cyclone axis. The pre-motor filter has an outer perimeter defining a volume and the cyclone axis and the motor axis each extend through a centre of the volume. The cyclone axis is generally parallel to the motor axis. When the openable front wall is opened, the front end of the cyclone stage is opened and has an opening, the opening has a diameter in the direction transverse to the cyclone axis, and the rear end of the cyclonic stage has a diameter that is generally equal to the diameter of the opening. The cyclonic stage is removable from a cleaner body which houses the suction motor with the openable front wall in a closed position. When the first cyclonic stage is removed, the pre-motor filter is accessible for removal.

A cleaning system includes a robotic cleaner and an evacuation station. The robotic cleaner can dock with the evacuation station to have debris evacuated by the evacuation station. The robotic cleaner includes a bin to store debris, and the bin includes a port door through which the debris can be evacuated into the evacuation station. The evacuation station includes a vacuum motor to evacuate the bin of the robotic cleaner.
