Abstract: A vacuum cleaner flexible duct. The flexible duct includes a helical frame and a helical strip. The helical frame includes a plurality of loops arranged about a helical axis and is formed of a rigid material. The helical strip is provided between the loops to seal the frame and is formed of pliable material. The helical strip has indents on an exterior surface of the duct. The helical strip is secured to the loops such that the interior surface of the helical strip is flush with the interior surface of the loops.

Abstract: There is provided a nozzle for a fan assembly. The nozzle comprises an air inlet for receiving an air flow, a first air outlet for emitting an air flow and a second air outlet for emitting an air flow. The first and second air outlets comprise a pair of curved slots that are provided on a face of the nozzle, and the first and second air outlets are oriented towards a convergent point. The first air outlet and the second air outlet may be oriented towards a convergent point that is located on a central axis of the face of the nozzle.
