When emptying a conventional potty you have to pour the pee and/or poo over the area where the child sits and any pee dribbles down the side of the potty.

You can pour the poo and wee through the duct out of the back of the Pourty away from where your toddler sits or touches with no messy dribbles. Simply clean by refilling the pourty with water and pouring it out the back again.

We cannot think why anybody would buy a normal potty when they could buy a Pourty.
