It is suggested that at least one of the sockets (30; 66) of the pneumatic tube or hose (28) comprises at least one magnetic element (80) adapted for interaction with at least one respective magnetic element (78) provided in a vacuum generation unit (2; 48) and/or in a vacuum utilization device (32; 44) in order to secure the socket (30; 66) of the pneumatic tube or hose (28) to the pneumatic port (26; 42; 64) of the vacuum generation unit (2; 48) or of the vacuum utilization device (32; 44) by means of magnetic force (82; 94; 100). Further, the invention refers to a pneumatic port (26; 42; 64) of a vacuum generation unit (2; 48) and/or to a pneumatic port (42; 64) of a vacuum utilization device (32; 44), to which the socket (30; 66) can be releasably attached and secured by means of the magnetic force (82; 94; 100).

An adapter frame for mounting onto a base, in particular a suction device, a system box and/or a roller board, and for receiving a particle collecting container for a cyclone pre-separator, where the adapter frame includes a rectangular underside and adapter frame peripheral walls extending upwards from the underside, and lower adapter frame couplers, designed to provide a releasable, vertically tension-proof coupling to the base when the adapter frame is positioned on the base. The adapter frame on its upper side has a container receptacle for receiving the particle collecting container, the horizontal inner contour of which tapers towards the underside, so that the container receptacle is able to receive and horizontally stabilise a particle collecting container having an outer contour tapering downwards.

A cyclone pre-separator for positioning on a particle collecting container, the cyclone pre-separator including a box-shaped housing and a cyclone unit arranged in the housing. The cyclone unit includes an air inlet, an air outlet, and a particle outlet arranged on a underside of the cyclone pre-separator, where the housing has an air inlet hose port connected to the air inlet and an air outlet hose port connected to the air outlet, and has lower housing couplers, adapted to provide a releasable, vertically tension-proof coupling to the particle collecting container, when the cyclone pre-separator is positioned on the particle collecting container.

A vacuuming device having a separating device for separating dirt particles from an air flow drawn in by the vacuuming device is provided, wherein the separating device includes at least one first separator and one second separator, and, in a base collecting tank of the vacuuming device, different regions of the base collecting tank can be separated from one another by a partition. In a second aspect, the invention relates to a method for exchanging a disposal bag in a vacuuming device.

A dust collecting device with an extendible and flexible air tube including a housing, a cover, an air tube, a dust collecting head, a filter material and a gas guiding device. The cover is detachably disposed on the housing and has an accommodating groove. The air tube is positioned in the accommodating groove and extendible and flexible, the air tube is capable of being extended to outside the accommodating groove and retracted to be accommodated in the accommodating groove, and a bending angle and an extension direction of the air tube is changeable by flexibility. The dust collecting head is disposed at the air tube, and is positioned in the accommodating groove when the air tube is shortened to be accommodated in the accommodating groove. The filter material is disposed inside the housing and close to the cover. The gas guiding device is disposed inside the housing.

A vacuum tool configured to be removably coupled to hose or wand of a vacuum includes a body including a first end, a second end, and a first longitudinal axis extending between the first end and the second end.
