Abstract: A fluid delivery system for a surface cleaning apparatus includes a fluid container configured for storing a fluid, a fluid distributor configured for delivering the fluid to a surface to be cleaned, and a flow controller configured for controlling a flow of the fluid from the fluid container to the fluid distributor. The flow controller includes an adjustable valve and is configured for operating in a first mode of operation that supplies the fluid to the fluid distributor at a first volumetric flow rate; a second mode of operation that supplies the fluid to the fluid distributor at a second volumetric flow rate that is lower than the first volumetric flow rate; and a third mode of operation that supplies the fluid to the fluid distributor at a third volumetric flow rate that is lower than the second volumetric flow rate.

Abstract: A surface cleaning apparatus includes a recovery tank, a suction nozzle in fluid communication with the recovery tank, and a suction source in fluid communication with the suction nozzle and the recovery tank to generate a working air path to transport debris-containing fluid including air and liquid from the suction nozzle into the recovery tank. An air/liquid separator can be provided within the recovery tank for separating liquid from air in the debris-containing fluid.
