  • Patent number: 6256834
    Abstract: The invention relates to a vacuum cleaner comprising a housing (1) accommodating a suction unit (7). The vacuum cleaner further comprises a dust container (11) in which a dust filter (21) can be placed. The dust container is detachably coupled to the housing and comprises a handle (33) and an opening (31) via which the dust filter can be placed. According to the invention, the handle is provided on a side wall (39) of the dust container, while the opening is provided at an upper side (35) of the dust container, the upper side of the dust container being directed towards an upper side (37) of the housing in an operational position of the vacuum cleaner. In this manner, it is prevented that the dust filter can fall out of the dust container or that dust can fall out of the dust filter when the dust container is detached from the housing. In a preferred embodiment, the handle of the dust container also is a unique handle for the housing, so that the construction of the housing is simplified.
