I'm envious of the people with no schedule. It's one of those things that I just can't imagine.

I do laundry on Mondays. My mother always did laundry on Mondays, and it just stuck with me. I'll wash a load or two mid-week, but mostly, it's all day Monday. That works out great, because after a busy weekend, we usually have no desire to go anywhere on Mondays, so it's a natural stay-at-home sort of day.
I have 6 tasks I try to do weekly. Dusting, vacuuming/mopping (mop only kitchen), purge magazines, change sheets, empty trash throughout house, and clean bathrooms. I sometimes do all this in one day, but usually it's 1-2 tasks a day. I keep a to-do list, and I just cross them off as I do them. I'm not one that minds a little dirt, so it doesn't ever get to the point where I'm thinking it needs to be done before the one week mark.
Daily, I do dishes (empty dishwasher in AM, load all day, run after supper), wipe down the outside of toilets (first time I use each one--I have a 3 year old boy; enough said), pick up toys (before nap time, before Daddy gets home, and before bed), and make the beds. That's about it for daily.
I try to do a "deep clean" type chore 15 minutes a day 3 or 4 days a week (thank you flylady). This works for me, and my house is usually tolerable.
Every now and then (first trimester pregnant, new baby, or if we've been sick), it gets out of control, and I call a "all hands on deck" clean. We clean like crazy for an hour or two on a Saturday morning or Thursday night. Dh is a really good cleaner, and he's always willing, so if I need it, I can always fall back on that.
