The moisture sensor and indicator for a wet pickup vacuum cleaner, more particularly a wet extraction type carpet cleaner, is positioned in the suction duct to sense when water droplets or moisture is traveling through the suction duct. An indicator is activated to indicate to the operator that water is being extracted from the carpet. The sensor may alternatively be located in the bottom of the floor-engaging portion where it contracts the floor. When the degree of moisture in the carpet exceeds a predetermined threshold an indicator is activated to indicate to the operator that the floor is still wet and to continue extracting moisture from the floor. Alternatively, the moisture sensor can be used as a safety device on a dry pickup vacuum cleaner. When moisture is detected within the suction duct, the motor-fan assembly of the dry pickup vacuum cleaner is disabled to prevent a potentially hazardous condition. Also, another sensor is positioned in the cleaner to detect when the moisture level of the solution or recovery tank reaches a predetermined level. An indicator is activated to indicate to the operator when the moisture level reaches the predetermined level.

Moisture indicator for wet pick-up suction cleaner

A pivoting handle and control arrangement is provided for a floor care appliance such as a vacuum cleaner. An actuator rod in the handle is utilized for remotely triggering a switch located in the lower part of the housing. The switch could be utilized for controlling a feature of the floor care appliance such as a surge control for a vacuum cleaner's suction motor. A trigger positioned on the handle is operatively connected to an actuator rod traversing the interior of the handle. The distal end of the actuator rod is in operative engagement with the switch when the handle is in the upright position. When the trigger is depressed, the actuator rod depresses the switch causing it to close. The feature controlled is thereby energized. When the handle is moved to the folded position, the actuator rod is folded with the handle and moved away from the switch.
