Apparatus and method for cleaning surfaces

An apparatus for cleaning a surface comprising:

• a) one or more constant pressure pumps;
• b) one or more fluid distribution manifolds;
• c) one or more one-way valves;
• d) one or more fluid vessels;
• e) one or more fluid vessel pipes;
• f) one or more downward pointing sprayer elements;
• wherein said one or more constant pressure pumps are operably linked to said one or more fluid distribution manifolds;
• wherein said one or more one-way valves are located along said fluid distribution manifolds below the linkage points of any of said one or more fluid vessel pipes to said one or more fluid distribution manifolds and above said one or more constant pressure pumps;
• wherein said one or more fluid distribution manifolds link to said one or more fluid vessel pipes;
• wherein said one or more fluid vessels are operably linked to said one or more fluid distribution manifolds through said one or more fluid vessel pipes;
• wherein said one or more fluid distribution manifolds are oriented to have an approximately horizontal section above said one or more constant pressure pumps;
• wherein said one or more approximately horizontal sections of the fluid distribution manifold are operably linked to said one or more downward pointing sprayer elements.
