ABSTRACT:
In order to develop a suction device for cleaning purposes having a collecting container, which includes a closable suction inlet, a suction outlet and a filter disposed therebetween and is connected to a suction unit by a suction line emanating from the suction outlet, the suction line being closable by an outlet valve and an external air supply closable by a supply valve being disposed at the side of the filter remote from the suction inlet, in such a way that it facilitates filter dedusting, it is proposed that the suction device has a valve coupling unit, which links the closing of an inlet valve associated with the suction inlet and/or the opening of the supply valve to the closing of the outlet valve.
