A suction apparatus for cleaning purposes includes a container, a suction subassembly, a filter element arranged in a container interior, and a pumping subassembly, where a mixture of a carrier fluid and particles of dirt can be taken in via a suction inlet and the particles of dirt are restrained by the filter element. The filter element is a filter bag through which the mixture is taken in by the suction subassembly. A filter bag restraining part subdivides the container interior into a filter bag accommodating space and a fluid delivery space, where the filter bag is arranged in the filter bag accommodating space and is prevented, by the filter bag restraining part, from expanding into the fluid delivery space, from which carrier fluid flowing around, or through, the filter bag restraining part is delivered by the pumping subassembly.
