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.

24. A surface cleaning apparatus comprising:
-
a chassis defined by a fore-aft axis and a perpendicular transverse as tor carrying and transporting cleaning elements along a direction of the tore-aft axis over a work surface supporting the surface cleaning apparatus, the cleaning elements disposed to clean across a cleaning width generally orthogonal to the fore-aft axis; a scrubbing module carried by the chassis, the scrubbing module comprising a smearing element and a rotatable scrubbing brush defining the cleaning width and located aft of the smearing element; and a liquid applicator disposed on the chassis and comprising a pump arranged to dispense cleaning fluid from a fluid supply container; wherein the smearing element extends from the chassis to reach the work surface across the cleaning width for smearing dispensed cleaning fluid along the work surface; and wherein the scrubbing module is formed as a separate subsystem that is removable as a unit from the chassis. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
