Autonomous coverage robot
First Claim
1. A surface treatment robot comprising:
- a drive system configured to maneuver the surface treatment robot over a cleaning surface, the drive system comprising right and left driven wheels;
a supply volume configured to hold a cleaning liquid;
an applicator in fluid communication with the supply volume, the applicator configured to dispense the cleaning liquid onto a portion of the cleaning surface;
a pad configured to engage the cleaning surface to support a forward portion of the surface treatment robot above the cleaning surface and collect the cleaning liquid distributed along at least a portion of the cleaning surface when the surface treatment robot is driven, the pad arranged forward of all of the wheels, the pad extending at least along a cleaning width defined by the right and left driven wheels, and the pad slidably supporting at least ten percent of a mass of the surface treatment robot above the cleaning surface; and
a baseplate configured to hold the pad.

Abstract
A surface treatment robot includes a chassis having forward and rear ends and a drive system carried by the chassis. The drive system includes right and left driven wheels and is configured to maneuver the robot over a cleaning surface. The robot includes a vacuum assembly, a collection volume, a supply volume, an applicator, and a wetting element, each carried by the chassis. The wetting element engages the cleaning surface to distribute a cleaning liquid applied to the surface by the applicator. The wetting element distributes the cleaning liquid along at least a portion of the cleaning surface when the robot is driven in a forward direction. The wetting element is arranged substantially forward of a transverse axis defined by the right and left driven wheels, and the wetting element slidably supports at least about ten percent of the mass of the robot above the cleaning surface.
