Abstract: A hand held vacuum cleaner having a housing, a motor-fan unit, a dust container, an air passage opening into the dust container and through which dust laden air is directed into the dust container, and at least one filter arranged after the dust container, as seen in the flow direction. The dust container has a first emptying opening, which is normally being covered by a lid and is sized such that it allows the dust collected in the dust container to fall out through the opening when the lid is opened. The dust container also has a second emptying opening. In one aspect, the second emptying opening is adapted to be fluidly connected to an external vacuum source via a connection. In another aspect, a similar device is provided, and adapted so the dust container can be emptied through the first emptying opening without removing the dust container from the vacuum cleaner.
