A utility vehicle can comprise a wheeled platform, a motor coupled to the platform and configured to propel the platform, at least one cleaning element coupled to the platform, wherein the at least one cleaning element is movable between a collapsed position and an expanded position, and one or more controls configured to move the at least one cleaning element between the collapsed position and the expanded position. The at least one cleaning element can also be movable between a raised position and a lowered position relative to the wheeled platform, and the one or more controls can further be configured to move the at least one cleaning element between the raised position and the lowered position.

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.
