Suction cleaning apparatus comprising a container adapted for the collection of a liquid is provided with an inlet for connection to a suction head adapted for picking up liquid whereby incoming air flow is directed substantially radially inwardly relative to the container and impinges directly on an inner wall whereby it is spread in substantially equal and opposite streams around the interior of the container. The inner wall surrounds a suction inlet whereby suction is applied to the interior of the container and the arrangement minimises the tendency for a vortex to be generated in air flow towards such suction inlet, thereby reducing the tendency of foam to be produced on the surface of the collected liquid within the container.

Apparatus for use in suction cleaning devices or the like comprising a container adapted for the collection of a liquid and including: a closed bottom wall; a lateral side wall which is circular in plan; inlet means for connection with a suction head adapted for picking up liquid, said inlet means being disposed in the lateral side wall of the container for directing incoming air flow substantially radially inwardly; suction inlet means for connection with a source of suction; reservoir means for cleaning liquid in the form of an annular trough supported within the container; means for delivering cleaning liquid from the reservoir means to suction head connected to said inlet means; and deflector means disposed between said inlet means and said suction inlet means and surrounding the latter, said deflector means comprising an outer part of said annular trough which defines an inner wall of circular form spaced inwardly from said side wall with a lower edge spaced above the bottom wall of the container.
