Claim:
1. 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 spray nozzle, the spray nozzle being operatively connected to the liquid pump in a manner such that the liquid pump is capable of forcing cleaning liquid out of the spray nozzle; 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 first and second agitators and an electric motor, the first agitator being operatively connected to the electric motor in a manner such that operation of the electric motor causes the first agitator to rotate relative to the vacuum inlet port, the second agitator being operatively connected to the electric motor in a manner such that operation of the electric motor causes the second agitator to reciprocate relative to the vacuum inlet port.
