The Petkit Eversweet Ultra is a large fountain with a 5-liter fresh tank, a separate 1.8-liter waste tank and a built-in AI pet camera. CNET's Tyler Lacoma scored it 8.5/10, finding it silent in continuous mode and praising the non-recirculating design, water heating and the features available without a subscription. He called it expensive at about $250, large, and slow to learn because of the number of app controls.

Full review
A two-tank fountain with a camera
CNET's Tyler Lacoma describes the Eversweet Ultra as large: a 5-liter water tank sits above a 1.8-liter wastewater tank, and the semi-transparent body makes water levels easy to see. He wrote that it takes up more space than most pet fountains.
The fountain does not recirculate water. CNET explains that it cycles water between the two tanks, with one small Cube C filter to replace occasionally, and that the waste tank needs emptying; Petkit recommends every few days. Lacoma found the components well made and durable, with a lift-out handle on the tank and dishwasher-safe key parts.
Camera and pet recognition
The camera has a 140-degree viewing angle and points downward, which CNET said limits privacy concerns. It pairs with a rear speaker for talking to pets, though Lacoma said the audio quality is not especially impressive.
The fountain supports up to 15 pet profiles built from face and body photos. In CNET's testing the camera identified the reviewer's cat whenever he came near even without a profile, and the app sorted clips by whether a pet only appeared or actually drank.
Controls and noise
From the app, CNET lists controls to drain and refill the tray, run a full flush, switch between continuous, intermittent and motion-activated flow, set automatic refills and heat the tray water to a chosen temperature.
Petkit says the fountain stays below 30 decibels. Lacoma heard it when it switched modes and refilled or emptied tanks, but in continuous mode he found it silent across days of testing.
Price and subscription
CNET's stated drawback is cost: the features make the fountain expensive at $250, and the controls take time to master. Longer cloud storage and vlogs of seven to 30 days need a Petkit Care Plus subscription starting at $4 a month, but CNET says AI recognition and a one-day video history are free, so a subscription is not necessary.
Strengths
- +CNET found it silent in continuous mode over days of testing
- +Water is not recirculated; it moves from a 5-liter fresh tank to a waste tank
- +AI camera recognised the reviewer's cat and supports up to 15 pet profiles
- +Most features work without a subscription, per CNET
- +Key parts are dishwasher-safe
Watch-outs
- −Expensive at about $250
- −Takes up more space than most pet fountains, per CNET
- −The many app controls take time to learn
- −CNET heard noise when it switches modes or refills and empties tanks; speaker audio quality is not impressive
How it compares
The Eversweet Ultra is the only fountain on this page with a camera, and CNET describes it as cycling water between two tanks instead of recirculating it as a pumped fountain does. Its 5-liter tank roughly matches the 168 oz PetSafe Drinkwell Platinum and is smaller than the 2.1-gallon Petlibro Capsule Dog Fountain. At $249.99 it costs several times as much as the Petcube Fountain, the other app-connected model here, and unlike the Petcube it has to be plugged in.
