We use a professional cleaning company and have every house inspected before and after cleaning. Every now and then we miss something. If it is major and we missed it, we can reschedule them to come back as their time allows. If it is not major, please simply clean it yourself. You will be responsible for doing that over the term of the lease anyway. If it is something you cannot live with contact the cleaning company directly and ask them to come review it. Much of the time, the houses are cleaned when the company leaves, but over several days of moving or measuring, the house accumulates foot traffic and lots of open doors, etc. quickly becomes dirty.
