I clean by floors. We have a two story house (I never go into the basement - husbands territory).
Monday's - laundry, vacuum and dust the first floor, clean the kitchen (well), clean the powder room
Tuesday's - upstairs bathroom and vacuum and dust the upstairs
Wednesday's - wipe down the counters in kitchen and any touch ups that need to be done on the first floor and clean up the entry way
Thursday's - this is our Co-op day, wipe powder room down
Friday - sheets, any other laundry, clean laundry room and iron anything that needs to be ironed
