Liquid Extraction Cleaning Device
A liquid extraction cleaning device comprises a vacuum pump, a liquid pump, a cleaning solution tank, a recovery tank, first and second spray nozzles, a spray selection switch, a vacuum inlet port, an agitator assembly, and a handle. The spray selection switch controls whether liquid is expelled from the second spray nozzle when liquid is expelled from the first spray nozzle. The agitator assembly comprises first and second agitators. The first agitator is configured to rotate. The second agitator is configured to reciprocate. The handle is pivotally connected to the rest of the liquid extraction cleaning device and is lockable in several pivotal orientations. The handle can also be pivoted forward from a rearwardly extending direction to an extent that it extends forward horizontally.

8 . A liquid extraction cleaning device comprising:
a vacuum pump;
a liquid pump;
a cleaning solution tank, the cleaning solution tank being configured and adapted to store a cleaning liquid, the cleaning solution tank being operatively connected to the liquid pump in a manner such that the liquid pump can draw cleaning liquid from the cleaning solution tank;
a recovery tank, the recovery tank being configured and adapted to store soiled cleaning liquid extracted from a floor, the recovery tank being operatively connected to the vacuum pump in a manner such that the vacuum pump can draw air from the recovery tank;
a vacuum inlet port, the vacuum inlet port being operatively connected to the recovery tank and the vacuum pump in a manner such that the vacuum pump is capable of drawing fluid through the vacuum inlet port and into the recovery tank; and
an agitator assembly, the agitator assembly comprising an agitator that is configured and adapted to move relative to the inlet port;
first and second spray nozzles, each of the first and second spray nozzles being operatively connected to the liquid pump in a manner such that the liquid pump is capable of forcing cleaning liquid from the cleaning solution tank out of the spray nozzle;
a liquid spray selection switch, the liquid spray selection switch being adapted and configured to selectively prevent cleaning liquid pumped by the liquid pump from being forced out of the second spray nozzle while permitting cleaning liquid pumped by the liquid pump to be forced out of the first spray nozzle, the liquid spray selection switch also being adapted and configured to selectively permit cleaning liquid pumped by the liquid pump to be forced out of the first and second spray nozzles simultaneously.
9 . A liquid extraction cleaning device in accordance with claim 8 wherein the liquid extraction cleaning device comprises wheels, the first spray nozzle is between the wheels and the vacuum inlet port, and the wheels are between the first spray nozzle and the second spray nozzle.
10 . A liquid extraction cleaning device in accordance with claim 8 wherein the first spray nozzle is a first distance from the vacuum inlet port, the second spray nozzle is a second distance for the vacuum inlet port, and the second distance is at least three times greater than the first distance.
11 . A liquid extraction cleaning device in accordance with claim 10 wherein the liquid extraction cleaning device comprises wheels, the first spray nozzle is between the wheels and the vacuum inlet port, and the wheels are between the first spray nozzle and the second spray nozzle.
12 . A liquid extraction cleaning device in accordance with claim 8 wherein the liquid spray selection switch is a mechanical fluid valve.
