1. A vacuum cleaner assembly comprising: at least one suction device with at least one basic body configured hollow at least in sections; with at least one first end with at least one suction inlet, in particular for connection with at least one of a suction tube or a suction hose of a vacuum cleaner;
the basic body divides at a second end into at least two suction ducts which are tubular in shape, each suction duct having at least one suction intake; wherein a suction arm is associated with each of the two suction intakes; and wherein the suction arms are pivotable about an associated suction duct, wherein the suction arms are retained in an initial position by at least one biasing device, wherein the suction arms protrude laterally from the basic body to the left and right, wherein the suction arms are pivotable against a force of the at least one biasing device, from the initial position to one or more pivot positions, whereby a rotation of at least 90° both in a first, forward, direction and also in a second, rearward, direction relative to the initial position can be obtained, and whereby the suction arms automatically reset by means of the at least one biasing device when the force stops acting against the at least one biasing device.
