A hand vacuum cleaner comprises a cyclone, a conical pre-motor filter that is positioned rearward of the cyclone and a suction motor. The pre-motor filter has a front end that faces towards the cyclone air outlet. The conical pre-motor filter has an open interior volume, an outer surface, which is an upstream surface of the pre-motor filter, and an inner surface, which is a downstream surface of the pre-motor filter.

Disclosed is a vacuum cleaner. In the disclosed vacuum cleaner, a dust container includes a casing which has one open side and in which a suction port is formed in a circumferential surface of the casing, a filter unit which is provided in the casing, allows air introduced through the suction port to pass, and filters out foreign matter contained in the air, and an inlet guide member which is provided on an inner surface of the casing corresponding to one edge of the suction port so that the air introduced through the suction port generates a vortex to guide foreign matter having a predetermined size or larger among the foreign matter to fall to an inner bottom of the casing and to guide foreign matter attached to a surface of the filter unit to be detached.

The present disclosure relates to a vacuum cleaner for separating and collecting dust and other contaminants by using a multi-cyclone and a mesh filter, including a cleaning unit for sweeping dust and foreign materials attached to the mesh filter along an outer circumferential surface of the mesh filter, and a rotation unit coupled to the cleaning unit for rotating the cleaning unit relative to the mesh filter, whereby the cleaning unit can clean a surface of the filter automatically or manually during an operation of the cleaner, so that the filter surface can be kept clean, and a load on a fan unit caused due to foreign materials or dust can be reduced.

A hand carriable surface cleaning apparatus can include a first cyclonic cleaning stage having an upper end, a bottom end spaced longitudinally below the upper end and a side wall extending therebetween. A second cyclonic cleaning stage may be positioned in the fluid flow path downstream from the first cyclonic cleaning stage and may be positioned above and overlie the upper end of the first cyclonic cleaning stage. The second cyclonic cleaning stage may be longitudinally translatable relative to the sidewall.

A filter assembly includes a filter housing, a first filter, and a second filter, wherein the first filter is a pre-motor filter, and the second filter is a post-motor filter, and both the first and second filters are fixed to the filter housing and are annular about a common axis.

A surface cleaning apparatus comprises an air flow path extending from a dirty air inlet to a clean air outlet and includes a cyclone bin assembly, a screen and a suction motor positioned in the air flow path. The screen is axially removable from the cyclone bin assembly.

A handheld blowing-suction integrated dust remover includes a main body, a handle, and a drive assembly. A first air vent and a second air vent are respectively formed at two opposite ends of the main body. A ventilating chamber is formed in the main body. Both the first air vent and the second air vent communicate with the ventilating chamber and the outside of the main body. The first air vent and the second air vent are respectively connected to elongated air tubes. The handle is connected to the main body. The handle is formed into an included angle with the main body to be held conveniently. The drive assembly is provided in the ventilating chamber and can utilize the elongated air tubes at two sides to drive the first air vent and the second air vent to suck air and blow air.

A surface cleaning apparatus has a filter assembly comprising a plurality of removable assembly portions. Each of the assembly portions comprises a portion of a pre- and/or post-motor filter media.

The subject matter of the invention is a filter element (13) for insertion into a vacuum cleaner, with an upper side (14), a lower side (15) which lies opposite the upper side (14), a filter body (19) which extends from the upper side (14) to the lower side (15) and which forms a wall (26) of a clean air space which is situated between the upper side and the lower side, and with a conveying opening (17) which is arranged on the upper side (14), opens into the clean air space, and through which an air flow which is driven by way of the vacuum cleaner can be conveyed. According to the invention, a deflecting surface (20) which extends in the direction of the lower side (15) is arranged in the clean air space below the conveying opening (17), which deflecting surface (20) is configured to deflect an air flow which is introduced through the conveying opening (17) in the direction of the wall (26) of the clean air space. The filter element (13) according to the invention can be relieved of filter cakes in a simple and effective way.

A vacuum cleaner and filter cleaning system includes a filter cleaning mechanism which allows the filter to be cleaned without removal from the vacuum. Operation of the filter cleaning mechanism both flows air backwards through the filter and strikes the filter to more effectively clean the vacuum filter. The vacuum allows for filter cleaning and debris disposal without significant interruption of the use of the vacuum cleaner.
