ABSTRACT:
The multifunctional vacuum cleaning appliance has a lower housing part provided with an electrically driven brush. A further housing part is allocated to the lower housing part. The further housing part incorporates the operational parts for vacuum generation, dust filtering and dust collection. The lower housing part can be coupled to the suction circuit of the further housing part. In addition to vacuum sweeping work with the complete assembly, the appliance can also be used for normal vacuuming work without spatial limitations because the further housing part is a pull-along cylinder vacuum cleaner which is detachably coupled to the lower housing part.
