The confirmed cleanup loop
Clean the School is presented by its creator as a classroom restoration game: find misplaced objects, interact with them and return them to the appropriate visible place. The public description specifically mentions books, supplies, chalkboards and desks, and says the experience contains more than 1,000 items. It also confirms that upgrades exist. It does not publish a named map list, room-by-room route, quest table, boss system or exact upgrade catalog. Plan around what the live classroom shows rather than assuming a location copied from a different cleaning game.
