1. An autonomous cleaning robot comprising:

  • a chassis of the autonomous cleaning robot having a lower surface defining a channel open to a cleaning surface,an air jet port and an air intake port disposed in the channel such that the air jet port is disposed along a first transverse edge of the chassis and the air intake port is spaced apart from the air jet port;

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

    a waste storage container carried by the chassis and in fluid communication with the air intake port;

    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 applying the positive pressure in a lateral direction at the air jet port to move loose particulates on the cleaning surface and applying the negative pressure at the air intake port to remove the moved particulates from the cleaning surface; and

    a debris guiding strip disposed aft of the channel, the debris guiding strip configured to direct the loose particulates moved by air exiting the air jet port toward the air intake port and including a first portion disposed aft of the air jet port and a second portion disposed aft of the air intake port.
