ABSTRACT OF THE DISCLOSURE A cleaning apparatus including cyclones (11, 52, 81, 107) connected to a uniquely configured receiving chamber (12, 53, 99, 112) is described. The chamber has a diameter furthest from the cone opening (32, 75, 93, 118) at least 3 times the diameter of the cone opening such that dirt is not re-entrained from the chamber. Also described is an apparatus with seal means (33, 76, 100, 117) between the receiving chamber and cyclone which provides a seal during air flow and which allows separation of the chamber and cyclone for dirt removal. Also described is a ring seal means (34, 104) around an open portion of the receiving chamber which allows removal of the chamber from an outer container (14, 51, 80) to facilitate emptying dirt.
