The sensor is the difference from a simpler fountain: it runs when an animal comes near rather than circulating all day, which makes a battery-powered unit last far longer between charges.
Four litres suits a multi-pet household or a dog, where the smaller 3.2 L model is really a cat fountain.

Styling notes
Sensor fountains take a few days for a cat to learn — it starting as they approach can startle them at first, so leave it running continuously for the first day if your cat is nervous. Keep it away from the food bowl. Four litres still wants emptying and rinsing every few days regardless of capacity.
