Abstract: The present invention relates to an aqueous ozone floor disinfection system. A floor cleaning machine traverses a floor surface entering a pre-hygienic zone prior to cleaning, cleaning within a midst-hygienic zone for a cleaning period, and moving away from the midst-hygienic zone creating a post-hygienic zone. An aqueous ozone generator receives water and generates an ozonated concentrate liquid. A post-hygienic mixer ratiometrically blends the ozonated concentrate liquid and water to form a post-hygienic ozone disinfection solution having a predetermined post-hygienic ozone treatment concentration. A post-hygienic nozzle spray of the post-hygienic ozone disinfection solution onto the post-hygienic zone portion of the floor surface for at least a post-hygienic treatment time absent agitation or removal by the floor cleaning machine improving disinfection of the floor surface. The service life of the aqueous ozone generator can be tracked and the disinfected floor surface can be GPS geofenced.
