That really is a very unpleasant job and I wouldn’t expect it of my cleaner, especially if S/he were on minimum wage or not much above it.
However, I do have sympathy for you if you’re unable to do it yourself.
I would either ask her to do ‘the nasty jobs’ as a one off, (deep clean) for additional pay or is there any chance you could use a stool to make it possible for you to do it yourself?

so that's not an option. DM's cleaner had stopped cleaning for her when she needed Carers as she had for other clients.
