It's Bluetooth enabled too, so it can connect to the Moona app.  > The pump looks like a smart speaker, but it's designed to send water to Moona's pillow pad. The pillow pad consists of a plastic layer that holds the water. It doesn't sound very cozy, but Moona says the plastic is "surrounded by memory foam for comfort." A motion sensor on the pad is supposed to monitor your sleep.
