As a student I worked as a cleaner in private homes.
I quickly learned at interviews to ask precisely what the lady who was considering employing me wanted done.
I wrote things down as she mentioned them, asked her if there was anything else and then if she wanted me to start made a fair copy of the list, which I asked her to sign.
I made it clear as politely as possible that I was not prepared to risk my neck by cleaning windows in flats on the third storey or higher, nor to balance on rickety stepladders to take down curtains or the like.
At that time, emptying bins, cleaning hair traps, toilets and fridges were expected of a cleaner.
I always asked how often they wanted the fridge cleaned, and made a point of saying that defreezing and cleaning a freezer was not part of my regular work, but that we could agree that I came in on another day to only do that, but that it would take longer than an hour to do.
I made sure to ask whether they wanted me to do laundry, as usually a wash-cycle took longer than the hour or so they were paying me for.
Most ladies preferred to load and start the washing-machine themselves, asking me to take out the washing and hang it to dry.
My system worked , so I suggest as others have that you specify your needs and expectations.
I would never assume that this or that was part of what a cleaner automatically would do, even although I am surprised to hear that bins were not emptied.
I remember once being asked next time I came to wash the doors and door frames. I had actually just done so, but felt that if I said that the good lady would probably comment that I hadn't done it well enough, so I said, "certainly" and the following week made a point of telling her I had done so.
She remarked that the paintwork looked so much better now, so I smiled and said I was glad to hear it, and didn't point out that they had looked like that the previous week too.
