Abstract:
1. A mobile surface cleaner comprising: a mobile body configured to travel over a surface; a source of a liquid; a liquid dispenser; a flow path from the liquid source to the liquid dispenser; an electrolyzing sparging device in fluid communication with the flow path and which lacks an ion exchange membrane; a functional generator in the flow path, which comprises an anode chamber and a cathode chamber separated by an ion exchange membrane and which electrochemically activates at least one of the liquid from the source or sparged liquid from the sparging device, wherein a flow of the liquid from the anode chamber is combined with a flow of the liquid from the cathode chamber along the flow path, or at the liquid dispenser to form a combined flow, or a combination thereof, which is dispensed from the liquid dispenser; and a control circuit which applies power to the sparging device and the functional generator such that the sparging device is operable to generate nanobubbles in the liquid by electrolysis, wherein the nanobubbles have a size that is too small to break surface tension of the liquid.
