1. An autonomous cleaning robot comprising:

  • a bottom surface having a first opening associated with a first cleaning zone;

    a drive system configured to maneuver the autonomous cleaning robot over a cleaning surface, the drive system comprising right and left driven wheels defining a transverse axis perpendicular to a fore-aft axis in a plane substantially parallel to the cleaning surface;

    a waste storage container;

    an air moving system configured to generate a negative pressure in the first cleaning zone, in which the first opening in the bottom surface is configured to allow particulates on the cleaning surface in the first cleaning zone to pass through the first opening and enter a receptacle carried by the cleaning robot;

    a second cleaning zone aft of the first cleaning zone, the second cleaning zone comprising a passive cleaning element fixedly attached to the cleaning robot and configured to be held in contact with the cleaning surface, in which the passive cleaning element extends along a cleaning width at least corresponding to a width of the first opening in the bottom surface, and during a wall-following mode operation of the autonomous cleaning robot, the passive cleaning element extends closer to a wall than the first opening in the bottom surface; and

    a liquid applicator configured to apply a cleaning fluid to the cleaning surface along the second cleaning zone.
