Most of the cleaners get tipped by the people coming to the Haram. People just dole out money on them.

If this is the case , then those brothers might not feel frustrated or oppressed. I read somewhere that the dua ( or cry ) from a majloom ( oppressed) ,even if he is Kafir , gets accepted readily. Imagine the dangerous scenario if a cleaner makes a bad dua while cleaning the harma sharif !! Big disaster !!
