Maintenance shouldn't be a project. Simply pull out the old core and push in the new one. No tools, no disassembly, and no mess, just a 3-second swap that gets you back to your day.
A fresh month, guaranteed.

*Testing conducted by a third-party laboratory.
Always in the loop.

FAQ
What is Fountain Cube C?
Fountain Cube C is a structural component that sits at the water outlet of Eversweet Ultra. It helps to inhibit biofilm buildup, keeping water fresher for longer between cleans.
Does EVERSWEET ULTRA work without Fountain Cube C?
Fountain Cube C is part of the fountain's structure and must remain installed at all times. One Fountain Cube C is included in the box.
Do I need to replace it?
Replacement every 30 days is recommended for optimal water quality.
How do I know when to replace it?
We recommend following the 30-day schedule for best results. The PETKIT app will also send you a reminder so you never have to think about it.
Is Fountain Cube C the same as a filter?
No. Most fountains require a filter to function. Fountain Cube C is a built-in structural component that adds a layer of freshness protection. The OneWay Mechanism is what keeps water clean by ensuring it never recirculates. Fountain Cube C simply enhances that further.
I absolutely love this fountain. The camera lets me check in on my cat while I’m away, and it’s really reassuring to see that they’re actually drinking water. It’s super quiet, easy to clean, and the app is simple to use. Definitely more expensive than a regular fountain, but for me it’s been worth every penny.
The cube is great. Just need to modify the bowl on the fountain. My high maintenance Persians go to the water fountain, which I have two of. I took one away to get them to use this one. They bypass it. Especially my two boys. The bowl needs to be shorter in the area where they are standing to reach over. They seem to rather drink out of a bowl on the other water bowl, which also dumps the water into a separate bowl and refills. The cube is just fine. I will look into the special cubes, can you make an all in one? The one for uti, bladder stones, fur balls, all that is needed.
It’s just my 4 Persians don’t seem to care about reaching down over the wall, they love how the other is designed to drink out on their face level. Also I love the camera it’s awesome and I love the fountain part, it’s actually too quiet. They need to hear a noise lol
With this fountain i can know which cats drink water or not and can check the camera around there too , can see the cats and what they do . I love it. It’s easy to clean and don’t need to buy filters anymore. I bought a lot of products from PETKIT and will be supporting them in the future
CATS ENJOY SEEING THEM SELFS AND DRINKINF FREASH WATER
I've tried a few pet fountains over the years, and honestly, I thought they'd all reached the point where there wasn't much left to improve. Turns out I was wrong.
The PETKIT EverSweet Ultra does something that made me go, "Why hasn't anyone done this before?" Instead of endlessly recycling the same water, it keeps fresh water coming into the drinking tray while the used water drains away. It's one of those ideas that's so obvious once you see it that you wonder why every fountain doesn't work this way.
I also didn't think I'd care about the camera, but now I check it way more than I expected. It's fun catching my cats sneaking over for a drink, and it's actually pretty useful to know who's drinking and when. If you have more than one pet, it's surprisingly nice to see their habits without playing detective.
Another thing I appreciate is that it doesn't feel like it was designed by someone who enjoys making cleaning difficult. Taking it apart is straightforward, and the automatic flushing feature helps keep everything fresh without me having to constantly think about it. Less scrubbing, more couch time.
My cats took to it almost immediately, which is probably the toughest review that matters. They drink more often, and I have a little more peace of mind knowing they're getting fresh water instead of the same bowl circulating all day.
Is it the cheapest fountain out there? Definitely not. But it also doesn't feel like just another pet gadget with Wi-Fi slapped on it. There are actual thoughtful improvements here that make a difference day to day.
Bottom line: my cats are happy, I'm doing less maintenance, and I get to spy on them being adorable once in a while. I'd call that money well spent.

It’s the BEST PET WATER FOUNTAIN EVER in my 25 years live with dogs.
Love not having to get filters anymore! Instructions could be better but no biggie I got it figured out. Camera is excellent
love it
From taking it out of the box, setting it up and my little frenchies first drunk, this thing is a breeze to use. I tried the deep clean mode, worked perfectly. It’s great peace of mind knowing our pup always has fresh water, highly recommend.
I love the cube. It’s a genius move for the water filtration system. I’m only waiting now for the other 3 cubes that do different things to ensure the health of my cats.
A major downside is the lack of a battery backup for power outages—a problem if the owner is away for a few days. This means the pets could be left without water for hours, requiring a neighbor to step in and put out a bowl of water. The dual-reservoir design is excellent. It would be helpful if the manufacturer specified which type of backup battery is compatible with this fountain model.
I really like this fountain for many reasons. Too many to list here.
I love love love this product. Less refilling as well as separated filter from drinking water.
works as advertised. awesome product!
loving my water fountain so far I do have one cat that is terrified of it so he won't use it yet. he has been getting closer to watch it, hopefully so he'll try. so can't quite get rid of my regular fountain yet.
Fountain Cube C
I love this fountain! It has been the best fountain I have purchased for my cats. They love it, the water constantly stays fresh and clean. I don’t have to refill it every 2-3 days! I recommend this fountain to dog and cat parents!
EverSweet Ultra with Camera Pet Water Fountain
I am loving the water fountain and the recordings to help monitor my pets’ health. It’s easy to clean, refill, and monitor.
Very easy to use and keeps the water clean/filtered.
The first unit worked great for the first two weeks, so I ordered a second unit. Both units are positioned next to each other. The first unit is now approximately one month old, and I am experiencing an issue where the recirculating pump stops flowing once or twice a day.
Each time this occurs, I completely disassemble the pump and clean it. However, there is never any debris or obstruction preventing the impeller from spinning. The app simply reports a “circulation issue,” but it does not provide any additional information about the cause of the loss of flow.
I would appreciate some clarification on how the system determines that there is a circulation problem. Specifically:
* Does the camera detect or verify water flow?
* Is the system monitoring the pump’s voltage or current draw?
* How is the expected or actual water flow calculated?
* What specific conditions trigger the “circulation issue” notification?
The pump and impeller are consistently clean and free of debris. Additionally, the other day the pump randomly began making a grinding noise. Again, there was nothing obstructing the impeller, and I was able to move it freely by hand.
Since the issue is occurring repeatedly despite the pump being clean and unobstructed, I would like to understand how the system is detecting the loss of circulation and whether this indicates a potential problem with the pump itself.
Hi there, we’re sorry to hear about the recurring circulation issue with your unit. We appreciate you providing such detailed information about what you’ve observed. Our support team is following up with you to look into the issue and help determine the cause. Thank you for your patience and understanding.
Cats don’t seem to mind it. I will try the other cubes, and see which ones they like best. Anything, to get them to stay hydrated.
Easy to clean and put together. Cats still getting used to drinking out of it. Easy to get wifi and program up and running. Membership is reasonable.
Interesting product
Great product so far. Item as described
The fountain has tracked my cats drinking accurately and has been a great help with making sure the reminder is consistent for cleaning each cycle. Very happy with it and my cat drinks alot more water than before.
Works very well, camera lets you know who's drinking. Easy to setup
