I think the fact that cleaning services are a lot less standardized is what drives the need to hire people. There's very little difference in logistics: its both easy to do an average job (just take the route google maps suggests) and its easy to monitor if contractors are doing a reasonable job. The impression I get for cleaning services from people who have hired them is that the person doing it will generally do the smallest/easiest amount of work possible in the allocated time, which leads to poor customer satisfaction/retention, so exercising more control as an employer is necessary.
