1. An autonomous cleaning robot comprising:

  • a chassis of the autonomous cleaning robot having a lower surface defining at least a portion of a channel open toward a cleaning surface;

    a drive system carried by the chassis and configured to maneuver the robot over the cleaning surface, the drive system comprising right and left driven wheels defining a transverse axis and configured to move the robot along a fore-aft axis substantially perpendicular to the transverse axis;

    a waste storage container carried by the chassis; and

    an air moving system carried by the chassis, the air moving system configured to generate a negative pressure and a positive pressure, and the air moving system comprises conduits configured to apply the positive pressure at a first portion of the channel and configured to apply the negative pressure at a second portion of the channel, the second portion of the channel in fluid communication with the waste storage container, whereinthe first portion of the channel defines an air jet port lateral to the fore-aft axis,the second portion of the channel defines an air intake port aft of the air jet port, andthe air jet port directs air along the channel in a lateral direction toward the air intake port.
