Founded in 1993, Janitor University’s initial course was designed to deliver a graduate-level education experience in a one-week immersion program, equivalent to one semester of study. The curriculum incorporates best practices and standardized processes in the cleaning industry, drawing on the accumulated wisdom collected from (OS1) users. Attendees of the course will gain an in-depth understanding of the essential elements required for a successful (OS1) operation, guided by the Janitor University Philosophy of Cleaning.
