Hand held vacuum cleaning apparatus (100) includes an elongate housing (122) which is cylindrical in shape. The housing (122) defines an inlet opening (108), an interior (124) and an exhaust opening (118). The housing (122) further defines, within the interior (124), a receptacle receiving chamber (112) in which, in use, a removable dust retaining receptacle (115) is located. The receptacle receiving chamber (112) is substantially circular in cross section and comprises substantially the whole of the diameter of the interior (124) in cross section. The apparatus (100) includes a flow inducer (117) located in the interior (124). In use, the flow inducer (117) induces air flow from the inlet opening (108), through the receptacle (115) in the chamber (112), through the flow inducer (117) to the exhaust opening (118).
