1. A robot vacuum cleaner comprising:

  • a cleaner body having a wheel disposed at a lower portion and a suction port through which contaminants can be drawn in from a cleaning surface;

    an air circulating mechanism for filtering contaminants from contaminant-laden air drawn in through said suction port and then jetting the contaminant-free air to an air jet opening, to scatter contaminant off the cleaning surface, said air jet opening formed adjacent to said suction port; and

    a sealing member for sealing off an area between the cleaning surface and said cleaner body to prevent contaminants scattered by the pressure of air jet from the air jet opening from being dispersed outwardly.
