Abstract
A particular multi-functional cleaning machine, in accordance with the principles of the invention, includes a water-tank and a liquid delivery line extending from the water tank to a high-pressure spray gun. The liquid delivery line has an inner end, a pump, and an outer end, with the inner end connected to the water tank, and the outer end connected to the high-pressure spray gun. The machine also has a cleaning-liquid draw line which is connected to the liquid delivery line using a cleaning-liquid injector. Because the machine has a separate cleaning-liquid draw line, an operator is able to choose from among any of a number of different cleaning liquids stowed in containers on the machine, and to draw a particular liquid through the draw line, into the liquid delivery line, where it may be combined with water from the water tank and subsequently sprayed onto a surface to be cleaned. The machine also incorporates a vac tank, a vacuum connected to the vac tank, and a vac-hose assembly, thereby enabling a user to vacuum spent cleaning solution and soil into the vac tank. Other aspects of the invention include a grout cleaning tool, a plunger gun, a liquid transport device, and a method of cleaning a soiled surface.

56. A method of cleaning a soiled surface, comprising the steps of:
-
providing a multi-functional cleaning machine, comprising;
a water tank containing water;
a liquid delivery line having an inner end, a pump, a cleaning liquid injector, and an outer end, the inner end connected to the water tank;
a spray gun connected to the outer end and having a liquid passageway and a liquid outlet;
a cleaning-liquid container;
a cleaning-liquid draw line connected to the cleaning liquid container and to the cleaning liquid injector;
a vac tank;
a vacuum connected to the vac tank; and
a vac hose connected to the vac tank;
aiming the liquid outlet of the spray gun at the soiled surface;
opening the liquid passageway of the spray gun, thereby spraying water and cleaning liquid onto the soiled surface, the cleaning liquid being drawn from the cleaning-liquid container, through the cleaning-liquid draw line, into and through the cleaning-liquid injector, and through the liquid delivery line and spray gun;
adjusting the pressure of the water passing from the water tank through the liquid delivery line and spray gun;
opening the liquid passageway of the spray gun, thereby spraying rinsing water onto the soiled surface; and
vacuuming water, cleaning liquid, and soil from the soiled surface, through the vac hose and into the vac tank.
