Our kids, the ones that live with us, are 14, 9 (who has autism) and 8. All three of them are expected to keep their rooms tidy and put their ironed clothes away, thats a given.
If they want extra money, they either clean the car (one does the outside, one does in the inside), or hoover right through, clean the bathroom, something like that.
I know everyone has different views but they are expected to clean up after themselves without reward because we believe it simply instills a sense a self worth, pride and sets them on a good path not to live like a dosser when they are older!
If their rooms aren't tidy when they have been in from school for about half an hour or more, they lose privileges such as going on the wii, or going out with their friends. It was tough for them when we first introduced these things but fine now.
They are also expected to put their washing in the linen basket, take their plates out after dinner, scrape them and put them in the dishwasher. When we have all the kids here its a family of 7, soon to be 8, and there would be a ridiculous amount of todying up after the kids to do if they didn't do these basic things, plus, it means we are out and about quicker so they have more fun!
