What actually goes wrong between visits
Very little of what makes a washroom unusable is dirt in the technical sense. It is an empty hand towel dispenser, a full bin, paper on the floor, a basin surround that has been splashed for six hours, and a fixture that somebody reported to nobody. All of those are the result of elapsed use since the last attendance, and none of them are fixed by scrubbing harder at six in the morning.
That is why an interim check is a different task from a service. A check is short, focused and consumable-driven: restock, empty, wipe surrounds, clear the floor, spot the fixtures, report anything broken. Written that way it takes a fraction of the time of a full service, and it addresses the failures that people actually notice. Write both as separate lines in the scope so a bidder cannot substitute one for the other.
