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.

Abstract
An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

14. A mobile robot, comprising:
-
a bottom surface that has a first opening associated with a first cleaning zone; an air intake port configured to receive loose particulates suctioned from the cleaning surface, in which the first opening in the bottom surface is configured to allow at least some of the particulates to pass through the first opening and enter the air intake port; a vacuum connected to the air intake port for suctioning; a waste container configured to collect the loose particulates suctioned up by the vacuum connected to the air intake port; a passive scrubbing element attached to a bottom surface of the mobile robot and disposed aft of the air intake port, in which the passive scrubbing element extends along a cleaning width at least corresponding to a width of the first opening in the bottom surface; and a liquid applicator configured to apply a cleaning fluid to the cleaning surface aft of the air intake port, wherein during a wall-following mode operation of the autonomous cleaning robot, the passive scrubbing element extends closer to a wall than the first opening in the bottom surface. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A mobile robot, comprising:
-
an air intake port configured to receive loose particulates suctioned from a surface; a vacuum connected to the air intake port for generating a negative pressure in a first cleaning zone and suctioning the loose particulates in the first cleaning zone through the air intake port, in which the air intake port faces the first cleaning zone or a region above the first cleaning zone; a waste container configured to collect the loose particulates suctioned up by the vacuum connected to the air intake port; a passive scrubbing element attached to a bottom surface of the mobile robot and disposed aft of the air intake port, in which during a wall-following mode operation of the mobile robot, the passive scrubbing element extends closer to a wall than the air intake port; and a liquid applicator configured to apply a cleaning fluid to the cleaning surface aft of the air intake port. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)
