Abstract
A vacuum cleaner, has a housing and a suction motor, arranged in the housing. When in operation, the motor draws in air via a suction opening and discharges the air via at least one outlet opening in the housing. A dust chamber in the housing collects dust entrained by the drawn-in-air when the vacuum cleaner is in operation. An odor filter is arranged in the housing downstream of the dust chamber. The odor filter includes a unit which temporarily prolongs the residence time of air drawn through the odor filter, in the odor filter during an odor suppression cycle.
