A dust scraping device for a cleaning apparatus includes a dust cup and a removable cyclone separation unit arranged in the dust cup. The dust scraping device includes a dust scraping member. The dust scraping member has a connection portion extending in a removal direction of the cyclone separation unit, and a dust scraping portion extending to an interior of the dust cup in a direction perpendicular to the removal direction and slidably abutting against the cyclone separation unit. The dust scraping device is mounted at the dust cup, and the dust scraping portion scrapes off at least part of debris on an outer side of the cyclone separation unit when the cyclone separation unit is removed from the dust cup.

A handheld vacuum cleaner (1) comprising a vacuum cleaner housing (2), a handle (3) connected to the vacuum cleaner housing (2), an intake head (4) through which outside air can be drawn in by the handheld vacuum cleaner (1), at least one exhaust port (5) through which the cleaned air can exit the handheld vacuum cleaner (1), an airflow circuit (6) that extends between the intake head (4) and the exhaust port (5), a suction unit (7) fitted on the airflow circuit (6), the suction unit (7) comprising an electric motor (7.1) and a fan (7.2) coupled to the electric motor (7.1) to generate an air flow in the airflow circuit (6) from the intake head (4) to the exhaust port (5), a waste separation device (8) fitted on the airflow circuit (6) upstream of the suction unit (7) and through which the air flow generated by the fan (7.2) passes when the handheld vacuum cleaner (1) is being operated, a removable tank (9) for receiving the waste separated by the waste separation device (8) and which is removably attached to the vacuum cleaner housing (2), a removable filter (14) arranged in the airflow circuit (6), the removable filter (14) being housed in a filter chamber (15) of the handheld vacuum cleaner (1), the filter chamber (15) being formed at least in part in the vacuum cleaner housing (2) and being arranged at least in part between the suction unit (7) and a wall of the vacuum cleaner housing (2). The filter chamber (15) comprises an access opening (15.1) to the removable filter (14) [sic] for accessing the removable filter (14) when the removable tank (9) has been detached from the vacuum cleaner housing (2).

A robot cleaner is provided. The robot cleaner includes a main body, a suction motor provided in the main body to generate a suction force, and a dust collector removably coupled to the main body to collect dust contained in air suctioned by the suction motor. The dust collector includes a first chamber to which the air, which is suctioned into the main body by the suction motor, is introduced, the first chamber including a filter to filter out dust in the suctioned air, and a second chamber arranged side by side with the first chamber, the second chamber including a connection port to which air, which is filtered b the filter in the first chamber, is introduced, and a cyclone dust separator to separate dust from the introduced air.

An example of an agitator for a vacuum cleaner may include a body and at least one deformable flap extending from the body. The deformable flap may include at least one taper. The at least one taper causes a cleaning edge of the deformable flap to approach the body.

A hand vacuum cleaner has a cyclone, a suction motor and fan assembly downstream of the cyclone and a post motor filter downstream of the suction motor and fan assembly. The post-motor filter housing has an openable bottom panel provided in the lower end of the hand vacuum cleaner.

Vacuum cleaner consisting of a dust container (1) and filters (2) within this, and above these a control space (3) for air and in the control space control housings (3a, 3b, 3c, 3d) and above these the central housing (4) and the underpressure space, and above this the suction unit (5) and the suction unit engine (6), all the units (1, 3, 4, 5) being in mutual communication. The control space (3) contains control valves (7, 8) for the air flow, by means of which, in normal use, the air flow is directed through the suction opening (9) in the dust container (1) to the exhaust air opening (10) in the suction unit (5) (arrows 9a, 9b, 9c) and the control valves comprise closing means, which, by opening the valve (7a) to the outside air and by closing the valve (8a) directs the air flow in the dust container in the filter under underpressure partly from the normal flow direction (9a, 9b, 9c) to the opposite flow direction (11).

A surface cleaning apparatus such as an extractor has a liquid delivery system, a separator, a collection chamber in communication a the separated element outlet of the separator, and a separated liquid collection container downstream from the collection chamber.

A filter device for a vacuum cleaner having a turbine device for generating at least one first and one second main air flow through at least a portion of the vacuum cleaner having and a control unit. The filter device has a first chamber including a first filter element, a first outflow opening, a first inlet opening and a first pressure surge element dividing the first chamber into a first chamber first space and a first chamber second space and reversibly movable between a first pressure surge element first position and a first pressure surge element second position, and a second chamber including a second filter element, a second outflow opening, a second inlet opening and a second pressure surge element dividing the second chamber into a second chamber first space and a second chamber second space reversibly movable between a second pressure surge element first position and a second pressure surge element second position.

A hand vacuum cleaner has a main body having an upper end having a dirty air inlet conduit and a handle. The handle has a hand grip portion that extends upwardly and forwardly. An assembly comprising an air treatment member and a pre-motor filter media is removably mounted to the main body.
