Abstract: An improved water vacuum extraction machine having a modular design allowing the detergent container to be removed when the machine is used in the vacuum mode when the detergent solution is not required. The water vacuum extraction machine includes a removable water filter to allow for the hydro filtration tank to be cleaned more easily. Further, an added filter is provided downstream of the suction motor to thereby reduce the amount of particles which are released into the environment. Specifically, the machine includes an outer casing including a bottom wall and a top wall and defining a chamber therein and a recovery tank removably positioned within the chamber. The hydro filter is disposed within the recovery tank and includes an inner tube and an outer which are concentrically arranged to define an annular space therebetween.

Abstract: A handle which is attachable to an electrified vacuum hose of a hydro-vacuum extraction machine, the hose including electrical wires encapsulated therein, a vacuum tube and a solution supply tube running parallel to the hose. The handle includes a handle portion secured to the vacuum tube, the handle portion having a valve chamber for receiving a valve having an actuator, a retainer for retaining the valve in the valve chamber and a cover for covering the valve chamber, wherein the solution supplying tube is attachable to the valve for supplying the cleaning solution thereto. The cover is pivotally secured to the handle portion. The handle further includes an electric plug which is retained in the handle portion and is electrically connected to the electrical wires. The handle portion includes a first half member and a second half member which are connected to each other and which define a hollow chamber therein. The plug is retained in the hollow chamber.

Abstract: A steam cleaner recovery tank has an inverted cup shape dome sealed thereto. An upright riser tube mounted to the recovery tank bottom wall extends into the dome. A flat horizontal plate intersects the vertical upright riser tube and supports a float ball at a rest position below a riser tube inlet port shielded from a dirt-free return air stream. The float ball rises by contact with liquid accumulating within the recovery tank. The float ball is of a density so as to be rapidly sucked into the inlet port by the dirt-free return air stream. A perforated cup integrally molded to the flat plate supports the float ball in one embodiment and forms a shield. In a second embodiment, a cylindrical wire mesh screen is fixed to the bottom of the flat plate, to the side of the riser tube. The float ball is positioned in the filter screen and the second circular hole constitutes the risers tube inlet port. An air imperforate shrink tube acts as a shield.
