A mobile sanitizing device may include a sanitizer solution dispenser module, a motorized wheel assembly, and a controller module. The sanitizer solution dispenser module may be operable to dispense the sanitizer solution. The motorized wheel includes at least one wheel and is coupled to the sanitizer solution dispenser module. The controller module includes a microcontroller and a memory, and is programmed to log a sanitization record into a sanitization history of at least one user, compare the sanitization history of the user with a sanitization standard, and control the motorized wheel assembly to cause the mobile sanitizing device to approach the user to dispense sanitizing solution to the user when the sanitization history does not meet the sanitization standard.
