It is a good idea to make a list of the things you want done, and to what level, and then to walk round with the cleaner, discussing it and listening to their suggestions, so you are in agreement.
The list should have things to be done on every visit (e.g. hoover the stairs, bl;cklead the grate), things to be done once a month (e.g. wash the door handles, polish the brass knocker) and a list of things to be done in rotation when they can be fitted in, one of them to be done each visit, start at the top and work down, (e.g. dust the cobwebs off the ceiling with your special long brush).
It is important to walk round with the cleaner annotating the list. Some will, and some won't. e.g. clean the oven; take your sheets off the bed and put them in the washer, change the towels, iron your shirts, polish the silver, put clean things in the drawers. Some won't dust your glass and china ornaments, either because they are too fiddly, or they don't want the blame for breakages. IMO you need, for example, to keep the loo clean yourself so they are not expected to do vile cleaning, and I think you ought to collect up the washing and put it in the machine, they may not want to handle your family's grimy stuff.
