Patent ID: 7959789

Claim:
A method comprising: a) moving a mobile floor cleaning device along a floor; b) electrochemically activating a liquid on the mobile floor cleaning device by converting the liquid into an anolyte electrochemically activated (EA) liquid and a catholyte EA liquid with a functional generator comprising an ion exchange membrane, where the anolyte EA liquid and the catholyte EA liquid have oxidation reduction potentials (ORPs) outside a range of ±50 mV; c) combining all of the anolyte and catholyte EA liquid produced in step b) to form a combined anolyte and catholyte liquid on the device without an intermediate step of storing either of the anolyte or catholyte liquids produced in step b), wherein the combined anolyte and catholyte liquid neutralizes to an ORP between ±50 mV within 1 minute from the time the anolyte EA liquid and the catholyte EA liquid are produced by the functional generator; and d) dispensing substantially all of the combined anolyte and catholyte liquid from the mobile floor cleaning device upon electrical activation in step b), while moving the mobile floor cleaning device in step a).
