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 debris bin includes a box body, a debris suction opening, and a debris outlet opening. The box body has an inner cavity. The debris suction opening is defined on the box body and communicates with the inner cavity of the box body. The debris outlet opening is defined on the box body and communicates with the inner cavity of the box body. The inner cavity is provided with a supporting surface for supporting debris. The supporting surface is inclined, and a top edge of the supporting surface and a bottom edge of the supporting surface are arranged parallel to each other and horizontally. The debris outlet opening is located at a side of the bottom edge of the supporting surface.

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 cyclonic separating device includes first and second cyclonic separating units. The first cyclonic separating unit is fitted over the second cyclonic separating unit. The second cyclonic separating unit includes first cyclones and second cyclones respectively arranged in a ring shape. Dust falling ends of the first cyclones define an accommodation space therebetween. The second cyclones partially extend into the accommodation space. Each first cyclone comprises first, second and third cone sections, each of which has a cone structure; airflow sucked in the first cyclones is sequentially separated by the first, second and third cone sections, and dust in the airflow is discharged from the third cone section; a central axis of the first cone section is parallel to a longitudinal axis of the dust cup; and an angle between a central axis of the second cone section and a central axis of the third cone section is 5°-20°.
