Abstract: A system and method for dispensing a treatment fluid is provided. The system includes a surface maintenance machine, a fluid reservoir, an air blower, and one or more fluid dispensing systems. The one or more fluid dispensing systems each include one or more nozzles in fluid communication with the air blower. The air blower generates an air pressure and dispenses air through the one or more nozzles while the treatment fluid is dispensed through the one or nozzles. The dispensing of air and treatment fluid dispenses the treatment fluid in a mist, fog, or spray to a surface. A method for dispensing a treatment fluid is also provided. The method includes generating an electrically charged treatment fluid and dispensing the electrically charged treatment fluid from the one or more nozzles to a surface.

Abstract: A surface maintenance machine comprises a surface maintenance head assembly with attached surface maintenance tool for collecting debris/fluid using a fluid delivery/recovery system. Embodiments include an outlet nozzle configured to dispense cleaning fluid exiting the outlet nozzle on the surface maintenance tool. The outlet nozzle is fluidly connected to a cleaning fluid source which can vary the intensity of cleaning fluid exiting the outlet nozzle such that different intensities of the cleaning fluid correspond to the cleaning fluid being dispensed on different areas of the surface maintenance tool. Embodiments also include a second outlet nozzle, located opposite the first, which is configured to dispense cleaning fluid exiting the outlet nozzle on the surface maintenance tool. Further embodiments include a pump which can vary the intensity of cleaning fluid exiting the outlet nozzle in a cyclical manner and suspend the cleaning fluid from exiting the outlet nozzle.
