Surface cleaning apparatus having a fluid distributor

A surface cleaning apparatus comprising:

• a fluid delivery system configured for storing a fluid and delivering the fluid to a surface to be cleaned;
• and
• a fluid recovery system configured for removing spent fluid and debris from the surface and storing the spent fluid and debris, wherein the fluid delivery system includes:
• a fluid container configured for storing the fluid and having a container outlet;
• a fluid distributor configured for delivering the fluid to the surface to be cleaned and including a spray bar having a plurality of spray bar outlets configured for dispensing the fluid to the surface to be cleaned;
• a flow controller configured for controlling a flow of the fluid from the fluid container to the fluid distributor, wherein 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;
• wherein the adjustable valve has a valve body that includes an inlet, a first outlet spaced apart from the inlet and having a first diameter, a second outlet spaced apart from the first outlet and having a second diameter, and a valve piston slidably mounted within the second outlet;
• and
• wherein the fluid delivery system further includes:
• a flow control valve disposed between the container outlet and the flow controller;
• and
• a Y-connector that couples the flow control valve and the flow controller to the spray bar;
• wherein the Y-connector includes an outlet, a high-flow arm fluidly coupled to the outlet and to the second outlet of the flow controller, and a low-flow arm fluidly coupled to the outlet and to the first outlet of the flow controller.
