Break chores up and divide among those able to do them. Kids can vacuum and dust and even clean the tub and toilets on top of maintaining their own rooms. Schedule one day as normal chore day. I raised four boys. Someone would walk the dog, someone else would do laundry, another would do the dishes and the fourth would dry the dishes and put them away, switching chores daily or weekly. Also count the number of rooms that you have to clean and then "deep clean" one room a week or a month or a day, whichever suits your schedule. DO NOT try to do all of the cleaning for the whole house in one day. You will be exhausted. Remember a little dirt never hurt anybody.
