1. A portable surface cleaning apparatus, comprising:
- a base module for movement along a surface;
an upright handle pivotally attached to the base module;
a liquid dispensing system comprising;
a liquid dispensing nozzle for applying liquid to a surface to be cleaned;
a fluid supply chamber for holding a supply of cleaning fluid;
a fluid supply conduit fluidly connected to the fluid supply chamber and to the dispensing nozzle for supplying liquid to the dispensing nozzle;
a fluid recovery system comprising;
a fluid recovery chamber;
a suction nozzle;
a working air conduit extending between the recovery chamber and the suction nozzle; and
a vacuum source in fluid communication with the recovery chamber for generating a flow of working air from the suction nozzle through the working air conduit and through the recovery chamber to thereby draw dirty liquid from the surface to be cleaned through the suction nozzle and working air conduit and into the recovery chamber;
the improvement comprising;
the suction nozzle includes a window that is at least partially transparent and an illumination source is mounted behind the window for illumination of the surface to be cleaned.
