Title: Apparatus for cleaning floors, carpets and the like

Abstract: 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.
