In Russia in my school most class coordinators/teachers organized an evening a month to clean up the classroom they are responsible for and spent most time in. There were contracted cleaners, but they mopped only the floor, while the condition of tables, shelves, blackboards etc were on students and their coordinator/teacher. Also in my school, we had regular roles you can fill to help staff by being a helper to a librarian, a dishwasher to a cook or being a coridor cop ensuring no one runs around - I moved lotsa books and washed tonsa dishes to bond with friends, smoke and skip classes.
