    Abstract: An air purifier includes a housing having a vented upper surface, a motorized fan assembly positioned within an interior volume of the housing and operable for discharging a filtered airstream through the vented upper surface, a hollow top cover, and an electric circuit, e.g., wireless charging electronics. The hollow top cover at least partially defines therein an electronics bay, floor vents configured to admit a portion of the filtered airstream into the electronics bay as a cooling airstream, at least one primary exhaust port for discharging the filtered airstream to a surrounding ambient environment, and at least one secondary exhaust port for discharging the cooling airstream to the surrounding ambient environment. The electric circuit is positioned in the electronics bay within the cooling airstream.

    Abstract: An air/liquid separation system for an extraction cleaner has a recovery tank assembly that includes a recovery tank, an inlet stack for receiving the working air stream with extracted liquid and debris entrained therein, an outlet stack for expelling air separated from the working air stream, and a lid assembly. A float is disposed adjacent to a curvilinear exterior side wall of a recovery tank, and the inlet stack and outlet stack are disposed transversely side-by-side in a tank chamber with the outlet stack between the float and the inlet stack. A bottom of the lid assembly defines an open bottom cavity within the tank chamber and above an outlet of the inlet stack. A lower surface of the lid assembly at the open bottom cavity inclines upward and outward from above the outlet of the inlet stack to an outermost side wall of the lid assembly.
