1. A surface cleaning apparatus (100) comprising:
- a chassis (200) defined by a fore-aft axis (106) and a perpendicular transverse axis (108) for supporting cleaning elements thereon and for transporting the cleaning elements over the surface along the fore-aft axis (106) and wherein the cleaning elements are disposed to clean across a cleaning width W disposed generally orthogonal to the fore-aft axis (106) with a left end L and a right end R defining opposing edges of the cleaning width; and
, a liquid applicator (700) comprising at least one nozzle disposed at one of said left end L and said right end R for ejecting cleaning fluid therefrom, said cleaning fluid being ejected with sufficient volume and pressure to distribute cleaning fluid across the cleaning width W.

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 cleaning elements arranged to spray a liquid cleaning fluid onto the cleaning surface across a cleaning width. The cleaning fluid mixes with contaminated on the floor, which become emulsified or otherwise mixed with the cleaning fluid. The robot further include cleaning elements configured to suction up waste materials and particularly the liquid waste material generated by the mixing of the cleaning fluid and contaminates.

18. A method for cleaning a surface with a cleaning apparatus 100 comprising the steps of:
-
transporting a chassis (200) over the surface in a forward transport direction defined by a defined by a fore-aft axis (106), said chassis (200) including cleaning elements supported thereon, and wherein the cleaning elements have a cleaning width disposed generally orthogonal to the fore-aft axis (108) and wherein the cleaning width has a left end L and an opposing right end R; and
,ejecting a volume of cleaning fluid from a first nozzle (712) attached to the chassis (200) at one of said left end L and said right end R, said first nozzle (712) 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 W. - View Dependent Claims (19, 20, 21, 22, 23)
