If you are contemplating a cleaner, perhaps you will find it helpful to look through this list and decide what you need.
Every week:
Kitchen work surfaces to be washed down.

Add any other items you need done and discuss with cleaner which of the above she does weekly and how long that takes, plus whether there are any of the above she is not prepared to do. You can also discuss whether she will do laundry, ironing, windows etc.
If you are not at home while she is working, discuss whether she should or should not answer phone, accept parcels etc.
