Identify things that they need to clean (put my clothes in the hamper, picked up my toys before bed, etc) and they get a sticker either from their parents at night or from you in the morning. Offer them a special outing or fun activity if they get stickers for all 5 days.
This could work but make it that they have to earn all 7 days so they're motivated to keep on top of things over the weekend when you aren't there!
