I salute you, Cleaners

Yesterday was a labour day. I was thinking something " Labour ".
Every morning,when I wake up and go for jogging, I find the streets are so clean, who does it? When the shopping centre is opened in the morning, we can see the whole shopping centre is so clean,who does it?
All the school / factory / government offices, corridors are so clean,who does it? This is because our cleaners. Without cleaners, you can imagine how is look like, so I respect cleaners, in flat cleaning job is one of the profession. I think we should call them environmental professional, this is my personal view, do you agree? Do you clean your house daily? Do you consider yourself the cleaner?
