Actually, that is all you have to do with an exclusively breastfed baby. If that grosses you out and you don't want to use a sprayer, you can use flushable diaper liners that you toss in the toilet with any solid waste on it. I'm not sure about formula fed babies. I'm sure you could get more info on that in the cloth diapering forum. When baby starts eating solids so that poop gets more solid, I do use a sprayer to get solid poop off before throwing the diaper in a dry pail.
It's really not that much work. If you are truly interested, you should look into it further.
