Abstract: An in-line switch and mixer control including a first restriction adjacent the outlet of a mixing device having a cleaning fluid and water inlet for controlling the flow rate from the mixer and a second restriction connected to the water inlet for varying the restriction of the water inlet to determine the mixing ratio. Initially, the first restriction is totally closed preventing any flow from the mixer and the second restriction is initially unrestricted. The first and second restrictions include a common actuator for sequentially operating the first and second restrictions to various intermediate restrictive positions.

Abstract: A fluid circuit for a cleaning device having a mixture with separate water and cleaning fluid inlets and fittings interconnecting a pressurized source of water and a pressurized source of cleaning fluid responsive to change the mixing ratio of cleaning fluid to water as well as to assure the degree of mixing. The outlet of the mixing device is provided to a spray nozzle wherein the mixed fluid is projected onto a cleaning surface by an air stream through the spray nozzle. A common pump provides two levels of air pressure, a high one to the spray nozzle and a lower one to the pressurized sources of water and cleaning fluid.

Abstract: A cam latch is provided to axially move a liquid container on a cleaning device and latch it thereto. The cam latch is received in a recess in the bottom of the cleaning fluid container thereby engaging a camming surface and aligning the container relative to the frame.

Abstract: A separator for a cleaning device having the air-liquid mixture introduced tangentially about the periphery of the conical shroud and the air outlet being interior the shroud.

Abstract: A suction nozzle for a cleaning device having a viewing area which slows down the speed of the liquid in the nozzle to permit viewing by the operator during operation of the cleaning device. The viewing area has a greater cross-sectional area than the nozzle as well as having eddy currents produced therein by a U-shaped nozzle to produce the slowing down.

Abstract: A suction nozzle having a horizontal trough at its outlet passage for retaining fluid left in a conduit connecting the nozzle to a suction source when the suction source is deactivated.

Abstract: A spotting control and trigger assembly having a first actuator for selecting the flow rate and a second actuator for selecting the mixing ratio of a control element which determines the flow rate and mixing ratio of water to cleaning fluid in a dispensing device. First and second actuators are interconnected to each other and are connected to the mixing and flow rate control by a common linkage.

Abstract: A tank unit to be removably mounted to a cleaning device having a clean water tank and a waste fluid tank displaced along a common axis and joined together by a connector which also provides an inlet to the waste fluid tank adjacent the top of the cleaning fluid tank.

Abstract: In order to provide a more compact package for economical storage and shipment, of a vacuum cleaner, or the like, the handle is manufactured in two portions. The two portions are configured to fit together in a predetermined manner with a telescoping relationship and to concomitantly complete electrical connections through connectors which are affixed to and internal to respective handle portions. At least one of the electrical connectors is allowed some longitudinal and rotational motion relative to its handle portion to facilitate electrical connector engagement and alignment. The assembly is held together by a fastener passing through the telescoped handle portions and one of the connectors. A portion of one of the connector assemblies also serves to limit the excursion of a compression spring surrounding a portion of the associated handle portion.
