EverSweet Ultra with Camera Pet Water Fountain
EverSweet Ultra is a water fountain that keeps water fresh without the upkeep. OneWay Mechanism sends fresh water to the tray and drains used water out. SpringFlow mimics natural running water, even the pickiest drinkers keep coming back. PETKIT AI camera tracks each pet and alerts you the moment something looks off. One tap cleans the tray. Fewer to-dos, for good.
Freshness shouldn't be built on any of these.
Fresh source built in, not filtered in.
Tired of changing filters just to keep water clean? OneWay Mechanism means water never recirculates, so there's nothing to filter. Fresh water goes straight to the tray. Used water drains into a separate tank on your schedule.
5L
Clean Tank
Holds up to 15 days of fresh water for a single pet.
1.8L
Waste Tank
Stores used water separately.
Fresh Springflow, even the pickiest ones drink.
Some pets just won't drink from a still bowl. SpringFlow gives them flowing water the way they naturally prefer. Three modes to find the one they actually like.
EverSweet Ultra delivers clean water on its own. CUBE C takes it further, inhibiting biofilm buildup and extending the time before residue forms. Optional, but worth it.
Fresh that requires less from you.
No filter changes.
OneWay Mechanism means water never recirculates. Nothing to filter, nothing to change.
No dead corners.
The pump is sealed separately from the water path. Fewer components in contact with water. Less residue, less buildup.
No hard disassembly.
Three parts, all dishwasher safe. Pop off, rinse or dishwasher, snap back on.
*Smaller parts can be easy to lose in the dishwasher. Put them in a container first.
An extra hand when life gets in the way.
Didn't get around to cleaning the tray? One tap flushes it with clean water, clears out the hair and buildup, drains everything into the waste tank, and refills itself. Not a full clean, but enough to keep things fresh between proper washes.
Note: this uses a good amount of clean water. Worth checking your tank level before running it.
No more guilt seeing an empty tray.
When the tray drops below 220ml, EverSweet Ultra refills it automatically. Turn it on once in the app, and it handles the rest. They never wait. You never have to worry.
In a multi-pet home, no one gets missed.
PETKIT 140° AI lens identifies up to 15 pets and flags irregular drinking patterns automatically.
A full visual history of every visit: when they arrived, how long they stayed, and how much they drank.
Get notified when the tank needs refilling, the waste tank is full, or a pet's drinking pattern looks off.
One tap turns the camera off, or set custom monitoring hours. End-to-end encrypted, only you can see the footage.

FAQ
Does the water actually stay clean without a filter?
Yes, because the water never loops back. Most fountains recirculate the same water, which is why filters are needed to manage buildup over time. Eversweet Ultra removes the loop entirely. Fresh water flows from the clean tank into the tray. Used water drains straight into a separate waste tank. They never mix. If you use SpringFlow mode, water in the tray will circulate to keep it moving, but you can always drain and refill the tray automatically or on a set schedule.
What makes this the best filterless pet water fountain?
Most filterless fountains remove the filter but keep the recirculating pump, so the water still loops through the same path. Eversweet Ultra replaces the entire architecture. OneWay Mechanism, split clean and waste tanks, AI health monitoring, and a self-cleaning tray. No filterless fountain offers all of that together.
How does it tell my cats apart? Do I need to train it?
Just add each pet's profile in the PETKIT app with a photo. The 140° AI camera learns to recognize each one from there, no additional training required. It supports up to 15 pets in one household.
How long does the 5L tank actually last with multiple cats?
For a single cat, up to 14 days. For two cats, roughly 7 to 10 days. Depending on how much each cat drinks. The transparent tank and app refill reminder mean you'll always know before it runs out.
How often do I need to empty the waste tank?
It really depends on your pet's drinking habits. If they drink quickly, you may rarely need to empty it at all. For slower drinkers or households that prefer fresh tray water more often, most single-cat homes drain it every 3 to 5 days. The PETKIT app sends an alert when the waste tank is full, so you never have to guess.
Do I need the CUBE to use the fountain?
Cube C is a structural component of the fountain and must remain installed at all times. It comes included in the box. Replacement every 30 days is recommended for optimal water quality, but the fountain continues to function beyond that period.
How often do I replace the CUBE?
We recommend replacing Cube C every 30 days for the best water quality. The fountain continues to function past that point, but replacing it on schedule ensures optimal performance. Simply swap the old one out when you're ready.
Will it spill or overflow?
No. The tray water level is monitored by AI camera continuously and only refills when it drops below 220ml, stopping automatically once full. The 1.8L waste tank holds used water between drain cycles without overflow. You'll also get a notification in the PETKIT app when it's time to drain.
Is it easy to clean?
Very. Three parts need regular cleaning: the fountain outlet, the magnetic strainer, and the water tray. All three are dishwasher safe. Pop them off, rinse or run them through the dishwasher, and snap them back on. For a deeper clean, pour boiling water into the tray to activate deep clean mode. That's genuinely everything.
How loud is it? Will this pet water fountain wake me up at night?
Generally no. EverSweet Ultra runs at 26dB, roughly the level of a whisper, and most owners forget it's on. During flushing and refilling cycles, it will be a little louder since the water needs enough force to clear out fur and buildup. We'd suggest placing it outside the bedroom if you're a light sleeper.
Can I see how much water is left in the clean tank?
Yes. The clean tank is transparent so you can check the water level at a glance. There's also a built-in indicator light that turns red when the level gets low - could be hard to miss. You can customize lighting when it triggers in the PETKIT app, which will also send you a refill reminder at the same time.
Does the water ever smell or go stale?
Much less than a traditional fountain. Because used water is immediately isolated in a separate tank, there's no stagnant loop building up bacteria over time. We do recommend keeping the fountain at room temperature and away from direct sunlight to get the best results.
Can I use this pet water fountain without the app?
Yes. The touch panel has a drain button and refill button for quick access. That said, we recommend pairing it with the PETKIT app to get the most out of it, including AI pet recognition, hydration tracking, and smart alerts.

It’s the BEST PET WATER FOUNTAIN EVER in my 25 years live with dogs.
They prefer their old fountain, the Petlibro Dockstream. I love the concept and tech, but they won’t drink from the new fountain so far.
Love not having to get filters anymore! Instructions could be better but no biggie I got it figured out. Camera is excellent
I've had this fountain now for several weeks. Out of the box, the fountain did not function properly. It continuously refilled until I had to empty and refill the tanks within one day. I emailed customer service, never got an email respond, the next day I contacted customer service via the app chat. They took some information from the back of my machine and it downloaded an update to the software. The fountain functioned properly for several days after that. Then I turned on the auto flush. Apparently, that went off in the middle of the night, and frightened my siamese cat. She was loving the fountain, but won't go near it anymore. Additionally, the refill began malfunctioning again. I cleaned up the fountain, and it worked properly again for about a day, then the refill kept going off every two minutes again. I emptied the waste water and filled the tank, unplugging it a while to get it to reset again. This cycle repeated again the next day. This time I turned off all the auto features. It appears to work properly, but if I try to use the auto features, it begins to malfunction until I clean and reset it. So, I love the fountain, but it doesn't function properly. Maybe mine is a lemon. Customer service told me they would email me, but that has yet to happen. Luckily, one of my cats still uses it.
Cats are drinking and it works great. Instill have not figured out how to get notifications when they do drink but I seen the video after searching for it. Great product.
Very good even if a bit louder than previous fountain.
Our dog and cat wont drink from this. I think its because the fountain spout is not reachable and the water tray is very swallow. Dont waste your money
This is one outstanding machine. It came beautifully packaged. It tracks my cats. It cleaned the water. It disposes of used water. The machine notifies me when things need to be done or the machine needs attention. It is by far the best fountain on the market. The PETKIT team is responsive if I have a question or a replacement part needed. PETKIT!
Cannot get the new fountain to pair with my other PetKit appliances in my account

Works great! Now i can monitor my cats water intake -very helpful
Awesome product… cats are getting use to it as they get nervous with all the amazing bells and whistles this product offers
EverSweet Ultra with Camera Pet Water Fountain
Nice! Everything had been great so far but I hate that I have another subscription to add. I already have multiple products so I’m hoping in the future they’ll definitely work on having a discount for having more than one of their products.
We've been loyal PETKIT users for years, and this fountain has exceeded our expectations. The smart alerts for low water and when the waste tank needs to be emptied make it incredibly convenient and take the guesswork out of maintenance.
With six small-to-medium dogs, we were especially impressed by the capacity. Our previous fountain needed to be refilled every day, but this one lasts about three days before needing more water. It's been a huge time-saver and has made keeping fresh water available for our dogs so much easier. We couldn't be happier with this upgrade!
it crashes for at least the movie gen
This machine is ultra quiet. My cats seem to prefer it over others they have had in the past. It was easy to assemble and easy to maintain.
My cats love it and after losing my first cat to ckd its nice knowing more about their daily water intake.
This fountain came with clear instructions and was easy to set-up. I downloaded the app and was ready to monitor my cats hydration. I have a cat who has FIC. He does not like water, which can worsen his condition. This fountain alerts me when he hasn’t had any water for a certain timeframe. This allows me to treat him accordingly. But my other cats LOVE this fountain. And I have fun watching them come up and drink. I have used all of the features and they work precisely and clearly. The flow of the water is just right and you have choices (I like the continuous flow). And draining the water into the overflow couldn’t be easier. Overall, I am extremely happy with the EverSweet Ultra and highly recommend it!
Amazing
Worth the wait. This water dispenser is truly the best.
Expensive but very good quality looks great
I have multiple Petkit products and each one requires it's own subscription. It would be nice if you offered a bundling plan so that I could have on charge for my account that would cover all the devices I want…eversweet, duel hopper feeder, puremax ultra and puremax duel. 3 picky cats multiple litter needs. I would
Like to monitor all of them but that adds up fast. I can't be the only one with more than one Petkit product.
Hi Lora, thank you for your feedback. We understand that managing multiple subscriptions can be frustrating when you have several PETKIT devices. A bundled subscription plan is already being considered by our team, and we hope to offer a more convenient solution in the future. Stay tuned, and thank you for helping us improve the PETKIT experience!
Best water fountain I’ve used to date. They got everything right with this one. Easy to clean and holds good amount of water with a stainless steel tray. Also I love how the water is always fresh and just not recirculating old water. Amazing job!
This unit is amazing. I have 2 pets in the home and finally it can last an entire week. Plus, it’s all fresh water instead of recirculating dirty water.
I already had an Eversweet fountain, which is the round style where the water bubbles from the top, and my cat loves it. I was excited about this new Eversweet Ultra, but unfortunately my cat doesn’t want to drink from it. I think the design of the tray may not be ideal for her, ergonomically, as she has to reach her neck across the wall of the drinking tray. This product may be better for larger pets such as dogs.
I’d been waiting for a self cleaning high capacity water fountain for ages. The Eversweet Ultra is so far everything I ever wanted.
