My son's allowed to leave up to 2 toys/ projects out and about (so that he can work on them over several days.
Aside from that he makes his bed every morning and picks up his room every morning (we homeschool, he has the time). He washes his sheets once a week, and his clothes twice a week -and puts them away. He vacuums once a week, or as needed (glitter explosions get dealt with as they come;). Until his chores are done he's not allowed electronics time in the morning... so he does them first thing. ((The rest of his chores include making and eating breakfast, showering, teeth, dressing, taking out the recycling, and washing his breakfast dishes.)). I help him do a deep clean of his room about once a month. Crank up the music and dancing and pizza and spotless making time it is.
He gets all of his daily morning chores (he has a few other afternoon things; like helping with projects or dinner) done in the morning in about 15-20 minutes. After his chores are done he can play until 10am.
Now, don't get me wrong... things do occasionally go to hail in a handbasket and things won't get done or they get skipped, imho that's just life... but pick a random day/week/month and that's the norm.
He's 8. ADHD-c (aka cleaning impaired, high energy particle). And this has been the standard for about 2 years.
