In a machine which cleans or buffs a floor by rotating a cleaning or buffing pad against the floor at high speed, simplified means are disclosed for supplying a controlled amount of cleaning fluid to the floor at the center of the cleaning pad. Vacuum which is created within the pad housing by the centrifugal action of the cleaning pad draws cleaning fluid out of a reservoir and into the central region of the pad. Flow is controlled and flow rate is set by limiting atmospheric vents. There is precisely controlled flow to the center of the pad, which may be continuous or on demand, no pump or moving parts of any kind are required, and the system is self-cleaning.

In a cleaning machine for removing soilage from a surface, a mobile frame, a rotary cleaning element on the frame for working on the surface and power means for rotating it, the rotary cleaning element being constructed and arranged so that, when rotated at a relatively high speed, it will create an air pressure differential, a source of cleaning solution on the frame, and a connection between the cleaning solution source and the air pressure differential so that the air pressure differential causes cleaning solution to be supplied from the source to the center of the rotary cleaning element.
