Abstract
A cleaning system includes a supply of purified water, a supply of cleaning agent, a mixing junction, and a distributor. The mixing junction is configured to combine a flow of the purified water and a flow of the cleaning agent and output a flow of cleaning liquid comprising the flows of the purified water and the cleaning agent. The distributor includes an output through which the cleaning liquid can be discharged. In a method of cleaning a surface, flows of purified water and cleaning agent are provided. The flow of purified water and the flow of cleaning agent are mixed to form a flow of cleaning liquid. The flow of cleaning liquid is then discharged to the surface.
Claims20
A surface cleaning system comprising:
- a supply of purified water selected from the group consisting of a supply of de-ionized water and a supply of filtered water;
- a supply of cleaning agent;
- a mixing junction configured to combine a flow of the purified water and a flow of the cleaning agent and output a flow of cleaning liquid comprising the flows of the purified water and the cleaning agent;
- and
- a distributor having an output, the distributor configured
- to discharge the cleaning liquid through the output.
A cleaning system comprising:
- a water filter configured to remove minerals from a flow of non-purified water received at an input port and discharge a flow of purified water through an output port;
- a first fluid flow path connected to the output port of the water filter;
- a supply of cleaning agent;
- a second fluid flow path connected to the supply of cleaning agent;
- a mixing junction configured to combine the flow of purified water from the first fluid flow path with a flow of the cleaning agent from the second fluid flow path and output a flow of cleaning liquid comprising the flows of purified water and cleaning agent;
- an aerator configured to aerate the flow of cleaning liquid and thereby form a foamed cleaning liquid;
- and
- a distributor having an output, the distributor configured to discharge the foamed cleaning liquid through the output.
- wherein the flow of filtered water is less than approximately 0.9 liters/min.
A method of cleaning a surface comprising:
- providing a flow of purified water;
- providing a flow of cleaning agent;
- mixing the flow of purified water and the flow of cleaning agent to form a flow of cleaning liquid comprising the flows of purified water and cleaning agent;
- discharging the flow of cleaning liquid to the surface.
