The invention concerns a device for separating and collecting trash for a trash collecting apparatus such as a vacuum cleaner, said device comprising a first tube with an air intake (13) capable of receiving the air sucked in and an air delivery outlet, a screw (11) substantially axially positioned in said first tube (8a), a second tube (9) with a diameter smaller than the screw external diameter and coaxially located in the first tube (8a) extension, in ventilating communication though one end to the first tube (8a) delivery end and connected by its other end to the suction unit by a first discharge conduit (14). The invention is characterised in that said device comprises a third tube (8b) arranged around the second tube (9) and connected to the first tube (8a) delivery end so as to provide between the second and third tubes (9, 8b) a second conduit for discharging the trash towards a filter and/or a container (10) in a secondary output flow. |
