  • Patent number: 9788699
    Abstract: A liquid extraction cleaning device comprises a main unit, a liquid pump, a flexible hose, and a hand tool. The main unit comprises a vacuum pump. The hand tool comprises a vacuum inlet port, an agitator, a spray nozzle, and a grip portion. The vacuum inlet port of the hand tool is operatively connected to the vacuum pump via the hose passageway in a manner such that the vacuum pump is capable of drawing fluid through the vacuum inlet port and into the hose passageway. The spray nozzle is operatively connected to the liquid pump in a manner such that the liquid pump is capable of forcing liquid out of the spray nozzle.

  • Patent number: 9717386
    Abstract: 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.

  • Publication number: 20130263404
    Abstract: A vacuum cleaner device comprises a main body, a brush device, and a vacuum driven motor. The main body has a primary vacuum inlet, a secondary vacuum inlet, and a vacuum outlet. The secondary vacuum inlet is operatively connected to the vacuum outlet. The brush device is configured and adapted to reciprocate relative to the main body. The vacuum driven motor is adapted and configured to be rotationally driven by air passing through the secondary vacuum inlet to the vacuum outlet. The vacuum driven motor is operatively connected to the brush device in a manner such that rotation of vacuum driven motor causes the brush device to reciprocate relative to the main body.
