Can't help with the peapod (avoided buying these) but All-in-one (aka AIO) is treated basically the same as a sposie - as in it's all in one piece - just rinse (if pooped, or after being on all night - usually stinks), dry pail and then wash, hang out to dry and then use again. You don't have to do anything to with inserts or snap in stuff. they do tend to take longer to dry though.
