Buckets, baskets, and anything that puts the toys into groups. Every child in my house from the youngest to the oldest learns that we play with one bucket or basket at a time. When we get bored, we pick it up and get something else out. Keeping the toys picked up helps. Having them play on a rug or on the couch or at a table helps too. They can be in a bedroom, at my feet when I sit in a chair, whatever...but they can't drag their toys around the house.
The big people in the house HAVE to follow the same rules...make a sandwich, put the stuff away BEFORE you eat it. The bathroom...clean part of it every time you go in there. The counters...wash them over and over all day long...dishes, keep the sink full of hot soapy water all day so that you can do them and clean stuff anytime it needs it.
It seems like I am always cleaning or sweeping something. But I sit for hours too and my house is always clean...put away the shoes, hang things up, have a place for your purse, buckets for bills with lids, clean out those closets... It works.
Commercial paper towel racks are awesome. It gets one thing off the counter and I have to bring paper towels in less often. Rolling toy carts with multiple baskets works wonders too.
Make those beds, keep the laundry going through everyday so it doesn't pile up.
Who said we shouldn't be cleaning most of the day at least some? I would say 15 minutes of work, 15 minutes of childcare, and 30 minutes of whatever else I want is how each of my hours break up all day and all night. I'm tired when I go to bed and sleep pretty darn well, even though I get up too often to use the potty.
