A vacuum cleaner having means for killing noxious small organisms trapped in a dust chamber (3) of the cleaner body (1) by circulating heated exhaust of an electric air blower (7) through the dust chamber. The vacuum cleaner comprises a temperature sensing element (36) for sensing a temperature in the dust chamber (3), a timer (46, 34) for timing a specified interval from a point of time when the electric air blower (7) is started in killing the noxious small organisms with heat, and a microcomputer (34) for stopping supplying electric power to the electric air blower (7) when a temperature sensed by the temperature sensing element (36) reaches a temperature fatal to the noxious small organisms or when the timer (46, 34) ceases timing the specified interval. |
