The first model has an entirely different mechanism. It consists of a wheel that turns, trapping the waste in sections wrapped around a central "spoke." It's hard to explain. But the downside is that it doesn't use the space inside very efficiently, and you have to end up emptying the device pretty often.

The new one, however, just puts everything into one large bag that is far easier to remove than the current system.

If you're so inclined, there's detailed flash animations of how the two work here.


I figured the shipping would be more than the cost of the product, but I don't mind that. What does make me pause, however, is that I've asked the company, and apparently the replacement cartridges for the old model don't work for the new one. So I'd probably want to get the 19.99 AND one of the replacement packages.

Any idea how much that would cost to ship? Looks like I'd have to commit to $35 to $80 before shipping...hmm...


Heh, I thought the same thing. I should just get a diaper genie!
