I used HomeJoy once, a student showed up and said "Wow your house looks pretty clean already, I'm not sure what I would even do". My apartment was tidy, but it wasn't clean (at least by my standards)
This actually highlights a big problem we had - aligning expectations of what "clean" meant between a customer and cleaner. Everyone has a different definition!
So your point is that you are unable to articulate what your standards are?
