The present invention relates to a multi-functional surface cleaning machine having a fluid tank, a primary fluid pump, a secondary priming pump, and at least one receptacle for holding concentrated cleaning chemicals. The receptacle(s) are in fluid communication with an operator controllable selector. The selector, either alone or in combination with a metering valve, may control which chemical(s) and the amount of such chemical(s) that will be allowed to flow to an inlet of a multi-inlet mixing member. A second input to the mixing member is a fluid to be stored within the fluid tank. The fluid and chemical which may be supplied to the mixing member may be mixed within the mixing member to create a cleaning solution, which may be supplied to any number of dispensing devices. One such device may be a spray gun for dispensing pressurized cleaning solutions onto a surface to be cleaned.
