Abstract
An apparatus is provided, which includes a sparging device and a functional generator. The functional generator is in fluid communication with the sparging device and includes an anode chamber and a cathode chamber separated by an ion exchange membrane.
Claims26
An apparatus comprising:
- a source of a liquid;
- a liquid dispenser;
- a flow path coupled between the source and the liquid dispenser;
- an electrolysis sparging device, which is in fluid communication with the flow path and lacks an ion exchange membrane;
- a functional generator, which is in fluid communication with the flow path and comprises an anode chamber and a cathode chamber separated by an ion exchange membrane;
- a mobile body, which carries the flow path, the electrolysis sparging device, the functional generator and the liquid dispenser;
- a least one wheel connected to the mobile body to move the mobile body across a surface to be cleaned;
- a cleaning tool connected to the mobile body;
- a pump in fluid communication with the flow path;
- and
- a fluid recovery device connected to the mobile body.
