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.

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.
