History
The first spray-and-vac system was developed by inventor Robert S. Robinson in 1997. A U.S. Patent was issued in 2001, and the technology has since been licensed by other manufacturers of cleaning equipment. A number of manufacturers in the professional cleaning industry now produce and market spray-and-vac systems or systems that are similar, and approximately 40,000-50,000 units have been sold worldwide Some systems are battery operated; others do not have vacuuming capabilities however they are still classified under this product category.
Spray-and-vac systems first became popular for restroom cleaning. However, over the years, users of the equipment have found a variety of uses for the equipment, including cleaning chairs and tables in cafeterias, cleaning carpets and hard-surface flooring, and deep cleaning a variety of surfaces.
An emerging market for spray-and-vac systems is public schools where the ability of the units to remove organic soils thoroughly, documented by Adenosine triphosphate (ATP) bioluminescence testing, is displacing traditional mop-and-bucket cleaning methods.
Correctional and foodservice markets are also appropriate for this method since they typically feature grouted, ceramic tile floors.

Famous quotes containing the word history:
“Yet poetry, though the last and finest result, is a natural fruit. As naturally as the oak bears an acorn, and the vine a gourd, man bears a poem, either spoken or done. It is the chief and most memorable success, for history is but a prose narrative of poetic deeds.”
—Henry David Thoreau (18171862)
“The history of all hitherto existing society is the history of class struggles.”
—Karl Marx (18181883)
“Humankind has understood history as a series of battles because, to this day, it regards conflict as the central facet of life.”
—Anton Pavlovich Chekhov (18601904)
