you dont HAVE to tidy his room every day at all ... just leave it and see what happens... the world wont end if he has a messy room for a bit.
as said you need to start now before he gets these ideas too far ingrained in his head - because if you dont you are setting him up for a life of misery, because in 20 years time majority of women definitely wont put up with this and he will be confused and may seek out a women who will be his servant... but there wont be many of them left by then.
start small, with the little jobs, like his bed, washing in basket etc, then start telling his pocket money must be earned... by doing the washing up etc
you will also make him self sufficient, he will be able to cope when he moves out
