1. A system for cleaning an object comprising a surface, said system comprising:

  • a steam source comprising a water tank and a heating mechanism to generate vaporized water;

    a cleaning head;

    a chamber mounted to the cleaning head and having an interior and an open end;

    a cleaning medium dispenser mounted to the cleaning head and fluidly coupled to said steam source, wherein said cleaning medium dispenser comprises a nozzle, located within said chamber, to deliver said vaporized water to said surface, and wherein impingement of said vaporized water with said surface partially dislodges debris from said surface and condenses said vaporized water to capture said debris that is dislodged from said surface;

    a first ultrasonic device mounted to the cleaning head and located within said chamber, wherein the first ultrasonic device is configured to deliver first ultrasonic waves to said object and to condensed water on said surface of said object;

    a second ultrasonic device mounted to the cleaning head and located outside said chamber, wherein the second ultrasonic device is configured to deliver second ultrasonic waves, which are different than said first ultrasonic waves, to said object and to said condensed water on said surface of said object; and

    a vacuum communicatively coupled to said chamber and configured to direct a vacuum airflow at said surface of said object; and

    wherein;

    said first ultrasonic waves and said second ultrasonic waves are in combination, focused within a cleaning zone to partially dislodge debris from said surface and to atomize said condensed water containing said captured debris; and

    said vacuum airflow is operable to collect atomized water containing said captured debris.
