1. A vacuum cleaner air/liquid separator, comprising:

  • an offset air/liquid airflow inlet for receiving an air/liquid airflow, with the offset air/liquid airflow inlet possessing a width and a height;

    a substantially cylindrical separator chamber communicating with the offset air/liquid airflow inlet, wherein the offset air/liquid airflow inlet is radially offset from the separator chamber;

    a lead-in track extending from the offset air/liquid airflow inlet and at least partially around the circumference of the separator chamber, with the lead-in track tapering from substantially the width of the offset air/liquid airflow inlet into the separator chamber, wherein the air/liquid airflow is entrained into a downward spiraling path in the separator chamber by the lead-in track;

    an impeller air inlet tube extending down through the separator chamber, with the impeller air inlet tube including an air only inlet; and

    a separator impeller chamber adapted to house an impeller for generating the air/liquid airflow, with the separator impeller chamber communicating with an air outlet located on an exterior of the air/liquid separator and with the impeller air inlet tube.
