Hard floor surface cleaner utilizing an aerated cleaning liquid

A method of cleaning a hard floor surface comprising the steps of:

• generating a foam-like aerated cleaning liquid by mixing pressurized air with a cleaning liquid;
• selectively conveying said foam-like aerated cleaning liquid to the hard floor surface and a scrubbing medium operatively coupled to the surface maintenance vehicle;
• scrubbing the hard floor surface with said scrubbing medium and said foam-like aerated cleaning liquid so as to loosen soil from the hard floor surface leaving behind a soiled solution of cleaning liquid and soil;
• and
• removing at least a portion of the soiled solution from the hard floor surface through a fluid recovery device.

• non-vacuumized transporting at least a portion of the soiled solution from the hard floor surface and into the recovery tank.

A movable device for a hard floor surface cleaning process comprising:

• an aerator in fluid communication with a cleaning liquid, said aerator generating a foam-like aerated cleaning liquid from the cleaning liquid;
• a fluid conveyor coupled to the aerator, said fluid conveyor transferring the foam-like aerated cleaning liquid into contact with the hard floor surface;
• a rotating scrub medium engaging the hard floor surface and the foam-like aerated cleaning liquid to loosen soil from the hard floor surface to leave behind a soiled solution of cleaning liquid and soil;
• and
• a fluid recovery device removing at least a portion of the soiled solution from the hard floor surface.

A surface maintenance vehicle for a hard floor surface cleaning process comprising:

• a tank holding water;
• a chemical dispenser, said dispenser delivering a chemical into water to form a cleaning liquid;
• an aerator generating an aerated cleaning liquid from the cleaning liquid;
• a fluid conveyor in fluid communication with the aerator, said fluid conveyor directing the aerated cleaning liquid into contact with the hard floor surface;
• a scrub brush engaging the hard floor surface and the aerated cleaning liquid to loosen soil from the hard floor surface to leave behind a soiled solution of cleaning liquid and soil;
• and
• a fluid recovery device removing at least a portion of the soiled solution from the hard floor surface.
