(54) Method and vacuum cleaner apparatus with germicidal action


(57) The vacuum cleaner apparatus comprises a chamber (11) for collecting the dust provided with a mechanical filtering system, an irradiation chamber containing a source of UV-C radiation, and an aspirator between the dust collection chamber and the irradiation chamber (13); the irradiation chamber (13) is in the form of an annular chamber disposed coaxially to the impeller of the aspirator, in which the suctioned stream of air with a microbial load, is made to re-circulate in a vortical state, subjecting the microbial load to the repeated action of UV-C radiations.
