A cleaner includes a housing, a body slidably coupled to the housing, a dust container mountable to the housing and detachable from the housing, and a pushing device slidably coupled to the dust container and mountable to the body and detachable from the body.

A hand surface cleaning apparatus has a front end and a rear end, an air flow path from a dirty air inlet to a clean air outlet, an air treatment member provided in the air flow path, a motor and fan assembly provided in the air flow path, and a filter provided overlying at least a portion of the filter, wherein the filter is removable radially outwardly.

The present disclosure relates to dust extractor (1) comprising a dust cyclone container (3) having a contaminated portion downstream an air inlet (2) and a clean portion downstream the contaminated portion, and a dust separating part (9) there between. The contaminated portion is provided with a dust container (59). The dust extractor (1) comprises a fine filter section (12) arranged adjacent to the dust cyclone container (3) and having a contaminated section and a clean section downstream the contaminated section, and a fine filter part (15) is adapted to be provided between the contaminated section and the clean section. An air channel (47) runs between a clean side of the dust cyclone container (3) and a contaminated side of the fine filter part (15). The dust extractor also comprises a mobility section (66) comprising wheels and a blower/fan motor (10) for drawing air from the air inlet (2) through the dust extractor. The dust cyclone container (3) has a center axis (48) along its longitudinal extension, and the fine filter part (15) is provided at a radial distance from the dust cyclone container (3) along a plane (P) perpendicular to the center axis (48) of the dust cyclone container (3), the plane (P) coinciding with the dust cyclone container (3) and a portion of the fine filter part (15). The blower/fan motor (10) is adapted to be powered at least partly by at least one onboard battery (61), and preferably two batteries (61), wherein the at least one battery (61) is arranged to be received in at least one battery slot (62) provided in the fine filter section (12) or in the mobility section (66).

A cyclonic separating apparatus comprising a first cyclonic separating unit and, downstream from the first cyclonic separating unit, a second cyclonic separating unit comprising a plurality of cyclones arranged fluidly in parallel about a first axis and a dust collector arranged to receive dust from each of the plurality of cyclones. Each of the plurality of cyclones in the second cyclonic separation unit comprise a fluid inlet and a fluid outlet, the plurality of cyclones being divided into at least a first set of cyclones and a second set of cyclones, the fluid inlets of the first set of cyclones arranged in a first group and the fluid inlets of the second set of cyclones arranged in a second group spaced along said axis from the first group. Each outlet of the plurality of cyclones in the second cyclonic separation unit is provided by a common plate-like vortex finder member.

A two-stage dust-air separation structure includes a cyclone separator and a spiral dust-air separation device. A first stage separation of dust from air is realized by a cyclone housing, and by arranging a second-stage cyclone barrel 5 inside the cyclone housing and arranging the spiral dust-air separation device at a barrel opening of the second-stage cyclone barrel, the dusty air, after going through the first stage separation, is guided by the spiral dust-air separation device to form, on an inner wall of the second-stage cyclone barrel, an airflow rotating towards the barrel bottom, and the dust in the airflow is driven by a centrifugal force to rotate downwardly to the barrel bottom and be collected in a second-stage dust collecting space, and the air in the rotating airflow is extracted by the negative pressure, thereby realizing a second stage separation of dust from air.

A vacuum cleaner, includes a dirty air inlet, a clean air outlet and an air channel arranged between the dirty air inlet and the clean air outlet. A vacuum generator is arranged inside the air channel. A first filter is arranged in the upper reach of the vacuum generator. A second filter is arranged in the upper reach of the first filter. The vacuum cleaner further comprises a state sensor. When in a second state, the first filter and the second filter are not combined, and the state sensor is not triggered. Missing mounting prevention detection of a main filter and a pre-filter can be realised at the same time by means of a micro-control switch, thereby saving on cost.
