Petkit’s latest Eversweet 3 Pro brings UV sterilization and a three-layer filter to the automatic fountain market, promising cleaner water and smart alerts-though its app has some hiccups.

Features and Design
The fountain’s plastic body houses a stainless-steel reservoir and a 2-ounce water reserve, ensuring cats always have water even if the main supply runs low. It uses a high-density fiber, coconut-shell activated carbon, ion-exchange resin, foam filter, and UV light to keep water clean. The USB-powered pump is wireless, and the app can show water level and filter status, but sometimes fails to notify when the flow stops.
