Abstract
A method and apparatus are provided for generating and applying a sanitizing liquid. The method includes moving a mobile floor cleaning device along a floor and electrochemically activating a liquid on the mobile floor cleaning device by passing the liquid through a functional generator having first and second electrode chambers that are separated by an ion exchange membrane such that the liquid activated in the first electrode chamber comprises Omolecules. Substantially all of the liquid activated in the first and second electrode chambers are dispensed from the device within 5 seconds of the time at which the liquids are activated by the functional generator without an intermediate step of storing either of the liquids produced in the first or second electrode chambers. At least some of the dispensed liquid is recovered from the floor with a recovery device carried by the mobile floor cleaning device.
