Check out this new portable, auto-butt-cleaning toilet bowl from Toto. It has a folding top for comfortable sitting and controls on the side for a bidet, butt spray (strong), butt spray (soft), and most importantly, the OFF button. It's made of wood (I have no idea why) and all the waste falls neatly into the tray below, so that you can pull it out, throw shit out, and then take the 44-lb potty to the next bedridden user.
