Abstract: Vacuum extraction recovery system assembly comprising a compartmentalized vacuum housing having a substantially air tight exterior wall, a vacuum creating mechanism in a first lateral portion of the housing interior, and a wall surface containing a constantly, directly and continuously freely open flow aperture therein and defining together with an adjacent portion of the exterior wall thereat an interior vacuum compartment in a second lateral portion of the housing interior which is laterally remotely spaced from the vacuum creating mechanism, such that the compartment is in constant, direct and continuous freely open flow communication with the remainder of the housing interior through such flow aperture and thereby constantly, directly and continuously maintained under vacuum condition corresponding to that in the remainder of the housing interior when a vacuum is created therein by the vacuum creating mechanism, for instance with the exterior wall having an access opening directly communicating with the c

Abstract: Double insulated, electrically energized liquid handling apparatus, usable without a separate ground line connection, e.g. a jet hot water extractor for dispensing and wet vacuum extraction recovery of rug and carpet cleaning liquids,including an electrically insulating container, e.g. of non-conductive material such as plastic, thereby providing a first exterior insulating barrier, which protectively contains a reservoir connected to a delivery pump adapted for connection in turn with an external applicator for pumping, preferably hot, liquid from the reservoir for application to a surface to be cleaned, an electrically isolated delivery motor, e.g. an open coil induction motor, including a rotatably mounted shaft operatively connected for driving the pump, preferably via a pump journal having a leakproof double seal bearing, and insulating mounting structure, e.g.

Abstract: A hot water extraction system including a water tank having means for connection to a container containing a vacuum motor and to a water extractor and a hot water applicator, the applicator having a connection for attachment to a normal faucet, a hose from the faucet passing through a chemical cleaning solution, and a valve for the emission of a predetermined amount of the water including the solution, the vacuum created by the vacuum motor in the container creating a vacuum in the water tank and thereby providing suction through a hose leading to the water extractor whereby the hot water containing the solution which has been emitted on to a surface such as a rug by the applicator is drawn into the water tank where it is accumulated until the cleansing is completed.

Abstract: Convertible wet and dry vacuum extraction system, in which compartments are provided in the interior of a vacuum housing that has a substantially air-tight exterior wall provided with a closable access opening communicating with one compartment as well as a housing inlet extending through the wall for outward flow connection with an external dry vacuum hose and for inward flow connection with a removable dry vacuum recovery bag positionable in a compartment which also is in communication with the remainder of the interior of the housing where means are provided for creating a vacuum in the housing, and in which a substantially air-tight removable wet recovery vacuum tank is insertable through the closable access opening and receivable at least partially in the compartment to convert the assembly of the system from dry to wet vacuum extraction, the tank having an inlet for flow connection with an external wet vacuum hose leading to a wet vacuum extractor, a tank surface portion provided with a flow opening and
