APPARATUS FOR CLEANING FLOORS, CARPETS AND THE LIKE ABSTRACT OF THE DISCLOSURE Suction cleaning apparatus for both dry suction cleaning and water extraction cleaning comprises a container for the collection of the liquid and having an inlet for connection to a cleaning head. A motor driven, air suction unit has an air inlet communicating with the container to apply suction thereto. A detachable reservoir is provided for the cleaning liquid so as to enable the apparatus to be used alternatively for wet cleaning. A shut-off valve can act to close the air inlet in response to the level of the contents of the container. A valve structure alternatively delivers air from an exhaust outlet of the suction unit either to atmosphere or to the interior of the reservoir so as to deliver the liquid from the reservoir to the cleaning head. This value structure includes a valve member biased into a first position in which exhaust air from the suction unit is allowed to flow to atmosphere. The valve member is so arranged so as to be engaged by a part carried by the reservoir when the latter is in use, so that the valve member is then moved to a second position in which the exhaust air flow from the suction unit is directed to the interior of the reservoir so as to apply a positive pressure thereto.
