A cleaning system of the invention may include an operator wearable torso belt, a swivel hook fastened to the belt, and a holder releasably hung on the hook, with the holder sized to releasably hold a chemical container. The cleaning system further may include a chemical container, a spray gun, a chemical draw line connecting the chemical container to the spray gun, and a liquid supply line extending from a multi-functional cleaning machine to the spray gun. If desired, the chemical holder may include a first compartment, a second compartment, and a third compartment. The first compartment holds the spray gun when the spray gun is not in use, the second compartment holds the chemical container, and the third compartment is sized to hold a tool such as a squeegee or the like.

What is claimed is: 1. A method of cleaning with a cleaning system, comprising the steps of: providing a cleaning system comprising: a fresh liquid tank, the fresh liquid tank containing water; a waste recovery tank; a fresh liquid pump operable to pump the water from the fresh liquid tank; a vacuum source for enabling a soil-containing fluid to be vacuumed into the waste recovery tank; a fresh liquid supply line fluidly connected to the fresh liquid tank and the fresh liquid pump, the fresh liquid supply line including an outer end; a spray gun/venturi chemical injector assembly comprising a spray gun assembly and a venturi chemical injector assembly at the spray gun assembly, the venturi chemical injector assembly including a fresh liquid inlet, a liquid cleaning chemical inlet, and an outlet, the outer end of the fresh liquid supply line fluidly connected to the spray gun/venturi chemical injector assembly; a liquid cleaning chemical container including an opening and containing a liquid cleaning chemical, the liquid cleaning chemical container wearable by an operator; a liquid cleaning chemical draw line including an inlet end and an outlet end, the inlet end fluidly connected to the opening of the liquid cleaning chemical container, and the outlet end fluidly connected to the liquid cleaning chemical inlet of the venturi chemical injector assembly, the liquid cleaning chemical draw line having a length sufficient to enable the operator to maneuver and use the spray gun for cleaning a surface when the operator is wearing the liquid cleaning chemical container; the spray gun assembly including a low-pressure setting in which the liquid cleaning chemical is drawn by suction into and through the venturi chemical injector assembly when the water is pumped into and through the spray gun, the spray gun assembly further including a high-pressure setting in which the liquid cleaning chemical is not drawn by suction into and through the venturi chemical injector assembly when the water is pumped into and through the spray gun; wearing the liquid cleaning chemical container, whereby the liquid cleaning chemical container stays with the operator but the operator is not hand-carrying the liquid cleaning chemical container; activating the spray gun in the low-pressure setting, and spraying a mixture of the water and the liquid cleaning chemical from the spray gun onto a surface being cleaned, the mixture formed at the spray gun/venturi chemical injector assembly, the liquid cleaning chemical supplied from the liquid cleaning chemical container worn by the operator; and activating the spray gun in the high-pressure setting, and spraying the water from the spray gun onto the surface being cleaned, the water sprayed from the spray gun having a pressure sufficiently high to provide a mechanical cleaning action on the surface being cleaned without damaging the surface being cleaned. 2. The method of claim 1 wherein the fresh liquid pump is rated at from about 200 pounds per square inch (PSI) to about 400 PSI. 3. The method of claim 1 wherein the surface being cleaned is a hard surface within an interior of a building. 4. The method of claim 3 wherein the hard surface is one or more of a floor, a wall, a divider, a door, a counter, and a bathroom fixture. 5. The method of claim 1 wherein the method steps are performed in a restroom, thereby cleaning the restroom. 6. The method of claim 1 including support structure operable to assist the operator in wearing the liquid cleaning chemical container. 7. The method of claim 6 wherein the support structure includes an operator-wearable torso belt. 8. The method of claim 7 wherein the support structure includes a fastener connected to the operator-wearable torso belt. 9. The method of claim 8 wherein the fastener includes a hook. 10. The method of claim 9 wherein the support structure includes a holder operable to hold the liquid cleaning chemical container, the holder adapted to be hung on the hook. 11. The method of claim 7 wherein the support structure includes a holder connectable to the operator-wearable torso belt and operable to hold the liquid cleaning chemical container. 12. A cleaning system comprising: a fresh liquid tank operable to contain water; a waste recovery tank; a fresh liquid pump operable to pump the water from the fresh liquid tank; a vacuum source for enabling a soil-containing fluid to be vacuumed into the waste recovery tank; a fresh liquid supply line fluidly connected to the fresh liquid tank and the fresh liquid pump, the fresh liquid supply line including an outer end; a spray gun/venturi chemical injector assembly comprising a spray gun assembly and a venturi chemical injector assembly at the spray gun assembly, the venturi chemical injector assembly including a fresh liquid inlet, a liquid cleaning chemical inlet, and an outlet, the outer end of the fresh liquid supply line fluidly connected to the spray gun/venturi chemical injector assembly; a liquid cleaning chemical container including an opening, the liquid cleaning chemical container operable to contain a liquid cleaning chemical, the liquid cleaning chemical container wearable by an operator; a liquid cleaning chemical draw line including an inlet end and an outlet end, the inlet end fluidly connected to the opening of the liquid cleaning chemical container, and the outlet end fluidly connected to the liquid cleaning chemical inlet of the venturi chemical injector assembly, the liquid cleaning chemical draw line having a length sufficient to enable the operator to maneuver and use the spray gun for cleaning a surface when the operator is wearing the liquid cleaning chemical container; the spray gun assembly including a low-pressure setting in which the liquid cleaning chemical is drawn by suction into and through the venturi chemical injector assembly when the water is pumped into and through the spray gun, the spray gun assembly further including a high-pressure setting in which the liquid cleaning chemical is not drawn by suction into and through the venturi chemical injector assembly when the water is pumped into and through the spray gun, whereby the operator may wear the liquid cleaning chemical container, whereby the liquid cleaning chemical container stays with the operator but the operator does not hand-carry the liquid cleaning chemical container, whereby the operator may activate the spray gun in the low-pressure setting, and spray a mixture of the water and the liquid cleaning chemical from the spray gun onto a surface being cleaned, the mixture formed at the spray gun/venturi chemical injector assembly, the liquid cleaning chemical supplied from the liquid cleaning chemical container worn by the operator, and whereby the operator may activate the spray gun in the high-pressure setting, and spray the water from the spray gun onto the surface being cleaned, the water sprayed from the spray gun having a pressure sufficiently high to provide a mechanical cleaning action on the surface being cleaned without damaging the surface being cleaned. 13. The cleaning system of claim 12 wherein the fresh liquid pump is rated at from about 200 pounds per square inch (PSI) to about 400 PSI. 14. The cleaning system of claim 12 wherein the surface to be cleaned is a hard surface within an interior of a building. 15.
