Abstract: A surface cleaning apparatus includes a recovery tank, a suction nozzle in fluid communication with the recovery tank, and a suction source in fluid communication with the suction nozzle and the recovery tank to generate a working air path to transport debris-containing fluid including air and liquid from the suction nozzle into the recovery tank. An air/liquid separator can be provided within the recovery tank for separating liquid from air in the debris-containing fluid.

Abstract: A surface cleaning apparatus includes a proximity-triggered user interface, and configured to provide one or more indicia to a user based on the proximity of the user to the surface cleaning apparatus. The surface cleaning apparatus can be provided with one or more proximity sensors, and the user interface is configured to receive input from the one or more proximity sensors and provide one or more indicia to the user based on the input.

Abstract: The present disclosure provides a surface cleaning apparatus that includes a recovery system that extracts liquid and debris with a drying cycle in which forced air flows through a recovery pathway of the recovery system to dry out components that remain wet and/or retain moisture after normal operation of the apparatus. The post-operation drying cycle can dry out components such as an agitator or brushroll, a brush chamber, a suction nozzle, a recovery tank, a filter, and any of the various conduits, ducts, and/or hoses fluidly coupling components of the recovery system together.

Abstract: A portable solar power management system includes (i) a solar panel interface to one or more solar panels, (ii) an energy storage interface to one or more energy storage devices, (iii) a charging circuit which routes the electrical currents from the solar panels to the energy storage devices; (iv) a load interface to one or more load devices, the load devices being powered independently on primary and secondary load circuits; and (v) a controller for controlling the operations of solar panel interface, the energy storage interface, the charging circuit the load interface. In addition, a secondary load control circuit and a programmable controller may be provided which routes the electrical currents from to the energy storage devices to the load interface, wherein the programmable controller, based on the sensing signals, also activates and deactivates the secondary load circuit.

Abstract: An extraction cleaner having a cleanout tool for use with a surface cleaning apparatus such as an extraction cleaner or vacuum cleaner includes a nozzle cleaning implement and a brush cleaning implement.

Abstract: A method of operating a plurality of power sources is provided. The method includes operating a first power source at a first power output and operating a second power source at a second power output. The second power source has a second operational capacity greater than the first operational capacity. First transient zone parameters are determined to operate in a first transient output power range. The first transient zone parameters include a first planned power output and a second planned power output constrained to be less than the first operational capacity.

Abstract: An extraction cleaner is provided with a removable recovery tank having a recovery container, a drain opening quick-empty valve, and an actuator assembly for emptying the recovery container. The drain opening can be provided on a lower portion of the recovery container. The actuator assembly can selectively open the valve. At least a portion of the actuator assembly can be provided on an upper portion of the recovery container.
