Hire a cleaner.
Do not allow any members of your family to buy you knick-knacks that need dusting

I think I could pretty much write a book actually, I used to be very into self-sufficiency and I make my own washing liquid and other such worthy things, even so I am all favour of saving myself from anything too tiring as I have dodgy hips and knees. Because I find bending forwards a problem, as in using a mop, to keep the kitchen floor clean between proper washes I tie a couple of damp rags to my feet and skate around the kitchen floor each evening, much to my GCs amusement. I'll get them doing it for me when they are a little bigger.
