Abstract:
A portable surface cleaning apparatus, comprising:a base housing adapted for movement along a surface to be cleaned; an upright handle pivotally mounted to the base housing; a liquid dispensing system mounted at least in part to the base housing and comprising: a first liquid dispenser associated with the base housing for applying liquid to a surface to be cleaned; a liquid supply tank for holding a supply of cleaning liquid; a first liquid supply conduit fluidly connected to the liquid supply tank and to the first liquid dispenser for supplying liquid to the first liquid dispenser; a second liquid dispenser separate from the base housing and including a spray nozzle for dispensing liquid onto the surface to be cleaned; and a second liquid supply conduit fluidly connected to the liquid supply tank and to the second liquid dispenser for supplying liquid to the second liquid dispenser; a cleaning fluid pump for delivering cleaning liquid from the liquid supply tank at least in part to the second liquid dispenser; a liquid recovery system comprising: a recovery tank mounted on the base housing and having a liquid recovery chamber for holding recovered liquid; a suction nozzle associated with the base housing and adapted to draw dirty liquid from the surface to be cleaned; a working air conduit extending between the recovery tank and the suction nozzle; an above-floor hose connected at one end to the recovery tank and having an open end for alternatively recovering liquid from the open end through the above-floor hose, the above-floor hose carrying the second liquid supply conduit and mounting the second liquid dispenser at the open end therof; a vacuum source in fluid communication with the liquid recovery chamber for generating a flow of working air from the nozzle through the working air conduit, or alternatively from the open end of the above-floor hose, and through the liquid recovery chamber to thereby draw dirty liquid from the surface to be cleaned through the nozzle and working air conduit, or from the open end of the above-floor hose and into the liquid recovery chamber to thereby recover the dirty liquid from the surface to be cleaned; the improvement comprising:a fluid reservoir mounted to the second liquid dispenser for dispensing a fluid onto the surface; and a fluid reservoir pump mounted to the second liquid dispenser for drawing fluid from the reservoir and for spraying the fluid onto the surface along with the fluid from the liquid supply tank.
