This is actually what I do... I printed off cards to put in each room and the kids and set a 15 minute timer, in that 15 minutes we do as much as we can and move to the next room. Every 30 minutes we get a 15 minute break, usually for a "dance party" :)
You give them the detailed job cards and then off they go to help you keep a clean house! I usually keep a point tally with my smaller kids (big kids dont really care for the point system, you just take away privileges from them if they don't cooperate!) Points = rewards like: dollars, soda, gum, movie rentals, screen time, etc.
