Autonomous surface cleaning robot for wet cleaning
First Claim
1. A surface cleaning apparatus comprising:
- a chassis defined by a fore-aft axis and a perpendicular transverse axis for supporting cleaning elements thereon and for transporting the cleaning elements over the surface along the fore-aft axis and wherein the cleaning elements are disposed to clean across a cleaning width disposed generally orthogonal to the fore-aft axis with a left end and a right end defining opposing edges of the cleaning width; and
, a liquid applicator comprising at least one nozzle disposed at one of said left end and said right end for ejecting cleaning fluid therefrom, said cleaning fluid being ejected with sufficient volume and pressure to distribute cleaning fluid across the cleaning width.

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.

18. A method for cleaning a surface with a cleaning apparatus, comprising:
-
transporting a chassis over the surface in a forward transport direction defined by a defined by a fore-aft axis, said chassis including cleaning elements supported thereon, and wherein the cleaning elements have a cleaning width disposed generally orthogonal to the fore-aft axis and wherein the cleaning width has a left end and an opposing right end; and
,ejecting a volume of cleaning fluid from a first nozzle attached to the chassis at one of said left end and said right end, said first nozzle being configured to eject cleaning fluid therefrom, said cleaning fluid being ejected with sufficient volume and pressure to distribute cleaning fluid across the cleaning width. - View Dependent Claims (19, 20, 21, 22, 23)
