Ithink that it is not correct to call a house cleaner "nany" because "nany" refers to the person whose only job is to take care of children where as a house cleaner is the person called a"maid" who cleans your house

The person who looks after children is called a "nanny" (note the spelling). A person who cleans your house, usually a woman, is often called a "maid."

We can use this word to the woman who looks after our children. And person who cleans we sometimes call caretaker or cleaner.
