Your comments work (or not) for a child. But these set a behavioral model that will continue on into the child's teen years. A child is taught respect for him/her self at home. You haven't included any ways to teach responsibility and cause and effect. Just imagine begging or dealing withan ungrateful, disrespectful teen that now uses your whole home as "his" room. Good luck.

I worked full time as did my husband. I told my sons to clean their rooms. I gave them a specific number of days. After the specific day, I came in with a broom, trash bag, and dust pan. I cleaned the room completely and threw the trash bag away in an unknow location. My sons learned that inaction has consequences.
My mom always did the "should I help you clean" phrase and god it's annoying, she has insanly high ocd so my room is clean enough (for normal standards)
Parents should learn to control their kids or dont take them if you arent ready for it. I dont want to listen to your kid yelling and screaming for a toy
