An automatic filter cleaning system e.g for cleaning a filter in a vacuum cleaner. The cleaning system has an electrical motor that drives/rotates, directly/indirectly, a piston which directly/indirectly opens a filter cleaning valve. The filter cleaning valve may open for a filter cleaning back flow air stream that thus cleans the filter. The piston is spring loaded and a piston guide ensures that the energy accumulated in the spring and piston is released during the rotation of the piston, thereby shortly opening the filter cleaning valve.

A hand vacuum includes a nozzle portion at a front end of the hand vacuum having a dirty air inlet. An air flow passage extends from the dirty air inlet to a clean air outlet in a main body rearward of the nozzle portion. The main body houses a suction motor in the air flow passage. First and second laterally spaced apart opposed arm members extend between the nozzle portion and the main body, and a volume is positioned between the nozzle portion, the main body and the opposed arm members. An air treatment member assembly comprising an air treatment member is removably positionable in the volume. A pistol grip handle assembly is provided on a lower portion of the main body. The handle assembly is positioned rearward of the volume and the air treatment member assembly is removable downwardly.

A dust collector and a device for beating dust in the same. The dust collector (10) includes: a main body (101) with a clean air outlet (1011); a filter section (102) set at the clean air outlet (1011); and a device for beating dust. The device for beating dust includes: a sliding rail (103) set on the outside surface of the main body (101) and opposite to the clean air outlet (1011); a slider (104) slidably set on the sliding rail (103); a poker rod (105) rotatably set on the slider (104); and a beating dust member (106) used for beating the filter section (102) and set on the poker rod (105).

A portable vacuum cleaner includes a housing and a filter assembly. The housing includes a dust collecting cylinder, a dust blocking cover and a main body. The dust collecting cylinder is opened to form an air inlet port and a mating port. The dust blocking cover is rotatably connected to the air inlet port of the dust collecting cylinder. The main body is detachably connected to the mating port of the dust collecting cylinder. A two-way locking structure is provided between the dust blocking cover and the main body. The two-way locking structure is adapted to lock or unlock the dust blocking cover and the main body simultaneously with the dust collecting cylinder, so that when the two-way locking structure is in a locked state, the dust blocking cover cannot open the air inlet port, while the dust collecting cylinder and the main body cannot be separated.

A dust collector is provided, which includes a housing, a filter screen, and a spiral air director. The housing is provided with an air inlet, an air inlet channel, an air outlet channel, an air outlet, and a dust collection chamber. The dust collection chamber is in communication with the air inlet and the air outlet through the air inlet channel and the air outlet channel, respectively. The filter screen is disposed in the air outlet channel. The spiral air director is disposed in the air outlet channel and located on at least one side of an air inlet side and an air outlet side of the filter screen. Air flow flowing through the air outlet channel is directed by the spiral air director to form a swirling air flow.
