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 handheld vacuum cleaner (10), including a main body (22) having a handle (98), a motor assembly (114) positioned within the main body, and a cyclonic separator assembly (26) removably coupled to the main body. The cyclonic separator assembly includes an inlet nozzle (42) having a dirty air inlet (14) positioned in the front of the handheld vacuum cleaner when the cyclonic separator assembly is coupled to the main body, and a cyclonic chamber (30) in fluid communication with the dirty air inlet. The cyclonic chamber defines a separator axis (34). The cyclonic separator assembly further includes a dirt collection region (38) configured to receive debris separated in the cyclonic chamber. The inlet nozzle includes an upstream height (270) measured perpendicular to the inlet axis and a downstream height (274) measured parallel to the separator axis. The downstream height is larger than the upstream height.
