A method of cleaning a hard floor surface with a surface maintenance vehicle including the steps of generating a foam-like aerated cleaning liquid, selectively conveying the 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 rotating 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. Additional aspects of the present invention include devices for performing the cleaning method.
RELATED APPLICATION
This application hereby incorporates by reference and, under 35 U.S.C. .sctn.119(e), claims the benefit of priority of U.S. Provisional Patent Application Ser. No. 60/308,773 filed Jul. 30, 2001.
The present invention is directed to a method of enhancing the appearance of a soiled porous surface. The inventive method includes applying a concentrated, alkaline, cleaning composition to the soiled porous surface. This concentrated, alkaline, cleaning composition is then allowed to remain on the surface for a period of time before it is rinsed with water. After drying, a maintainer composition is then applied to the surface. The maintainer composition includes a pore-filling component. The cleaning composition includes an alkaline source and, optionally, a solvent.
The present invention relates to an improved grout tool generally employed with a multi-functional surface cleaning machine having a fluid tank, a pump, and at least one receptacle for holding concentrated cleaning chemicals. In one embodiment, the grout tool employs fluid jets, adjustably connected via brackets, such that the jets are positioned at an angle relative to the grout tool body to allow fluid to hit a surface of an angle.
The present invention relates generally to an apparatus for cleaning or otherwise treating a floored surface that includes a platform adapted to support the weight of an operator. In addition, one embodiment of the present invention is capable of generally performing 360.degree. turns to facilitate the treatment of difficult to access portions of the floored surface.
A hard surface cleaner includes a motorized scrub head, a fluid recovery device, a primary cleaning liquid component container, a cleaning agent container, a flow control device and a fluid flow path. The flow control device is configured to supply a flow of cleaning agent from the cleaning agent container at a flow rate of less than approximately 10 cubic centimeters per minute to a flow of primary cleaning liquid component from the primary cleaning liquid component container. The fluid flow path is configured to receive a flow of cleaning liquid, which comprises the cleaning agent and the primary cleaning liquid component.A method of dispensing a chemical for use in a mobile hard surface cleaner includes driving a flow of cleaning agent from a cleaning agent container at a flow rate of less than approximately 10 cubic centimeters per minute, supplying a flow of primary cleaning liquid component from a cleaning liquid component container supported by the hard floor surface cleaner, combining the flow of cleaning agent and the flow of primary cleaning liquid component to form a flow of cleaning liquid, and dispensing the flow of cleaning liquid to either a motorized scrub head or a surface under the hard floor surface cleaner.
In a method of communicating data from a mobile floor cleaner to a remote receiver a data communication is initiated from a communicator of the mobile floor cleaner to the remote receiver and data is communicated to the remote receiver with the communicator.
