The PETKIT Eversweet Ultra hides its impeller from the app
- Unplug and lift out the motor block — disconnect the power adapter and remove the pump assembly from the reservoir before touching anything.
- Detach the pump faceplate — this exposes the magnetic impeller — the part the app's video never actually shows you reaching.
- Swap the tweezers — use non-magnetic precision tweezers instead of the kit's tool to lift the wet impeller out without dropping it.
- Flush, dry, reassemble — clear the motor cavity with a soft micro-brush, dry every contact fully, then rebuild away from the reservoir opening.
- No instructions in the app — the PETKIT app has nothing written about reaching or cleaning the impeller — only a short video.
- The video isn't the full job — it shows someone poking a small brush through a single hole in the housing, and that's it.
- Tweezers that won't grip — the tool in the box has soft plastic tips that slip off the impeller as soon as it's wet.
- Motor sounding rougher, or water smelling off — even though you rinse the reservoir regularly.
Your cat can still drink, but flow or filtration is off. Keep a backup bowl filled until this is sorted.
Why the app video isn't the complete cleanup
PETKIT ships the Eversweet Ultra with one help video and no written steps, and the video undersells what a real cleaning actually takes. Two gaps show up over and over in owner reports: the video stops short of the impeller chamber, and the included tool can't finish the job it implies you can do.
One video, one hole
The only guidance in the app shows someone inserting a small brush through a single access hole and calling it done. That clears loose hair near the surface, but the impeller chamber underneath keeps collecting biofilm and mineral scale that a hole-sized brush never reaches.
Tweezers that can't grip wet plastic
The double-ended tool in the box pairs a brush with tweezers that have soft, rounded tips. They work fine on a dry impeller sitting in your palm, but slip the moment the part is wet inside the housing — exactly the state it's in mid-cleaning.
The steps below cover the full teardown the app's video skips, plus the tool swap that makes the impeller easy to grab. Expect about 20 minutes.
How to access and clean the impeller
Work through Part A to reach the impeller, then Part B to clean and dry everything before you plug the fountain back in.
Skip the tweezers that come in the box
The kit's plastic tweezers slip on a wet impeller almost every time. A $7 pair of non-magnetic precision tweezers grips it on the first try and won't scratch the housing.
If the issue persists: replacement options
If the pump still grinds, hums, or runs slower after a full teardown clean, the impeller or the magnetic drive underneath it has likely worn down rather than just gotten dirty. At that point, check whether your unit is still under warranty before buying anything — PETKIT covers manufacturing defects on the Eversweet Ultra for a limited period.

Advanced: when cleaning isn't enough
Two scenarios come up after owners have already done the full teardown clean above.
Pump still doesn't run after cleaning
PETKIT's own troubleshooting for the Eversweet pump line points to the connecting prongs on the pump as a common failure point — check them for corrosion or a broken pin before assuming the motor itself is dead. Corrosion usually comes from water that sat on the contacts too long, which is exactly what Step 5 above is meant to prevent going forward.
How often to repeat this teardown
PETKIT recommends a full motor clean weekly for its Eversweet fountains, on top of rinsing the reservoir every 2-3 days. In hard-water areas, biofilm and mineral scale build up faster inside the impeller chamber than the app's quick-brush routine can keep up with — the full teardown above is worth doing every one to two weeks if your water is hard.
Frequently asked questions
Why are there no instructions inside the app for how to get to the impeller?
PETKIT's Eversweet Ultra app only includes a short cleaning video that shows brushing through a single access hole — it doesn't cover removing the faceplate or extracting the impeller. The teardown steps in this guide fill that gap.
What can I use if the tweezers included with my fountain can't grip the wet impeller?
Swap them for a pair of non-magnetic precision tweezers. The kit's plastic tweezers have soft tips that slip once the impeller is wet; precision tweezers hold it firmly enough to lift straight out without twisting the plastic shaft.
How do I prevent water leakage into the base after cleaning the motor?
Keep the motor block, faceplate, and power connector fully separated from the reservoir until everything air-dries completely — a few minutes on a towel is usually enough. Water pooling on the contacts before reassembly is the most common cause of a pump that won't power back on.
Conclusion
A missing how-to video shouldn't mean guessing your way through a wet electronic motor. Once you've swapped the tweezers and done one full teardown, the monthly upkeep on the Eversweet Ultra takes a few minutes. If you run into a step that doesn't match what you're seeing on your unit, describe it in the comments and we'll help you sort it out.
Still not fixed? Here’s what to do next.
Some faults are genuinely hardware, and no amount of cleaning or resetting will clear them. If you’ve worked through everything above and it’s still doing it, stop here rather than taking the unit further apart.
- Go to PETKIT directly. If the unit is still under warranty, let them replace the part rather than paying for it yourself — contact PETKIT support.
- Tell us what didn’t work. We rewrite bulletins when readers show us a case they don’t cover — compliance@pet-infrastructure.com. Tell us the model, what the lights are doing, and which steps you already tried.
- Ask other owners. Search Reddit for your model name plus the symptom (for example “PETKIT Eversweet Ultra Cat Water Fountain (AI Camera) not cycling”). Someone has almost certainly hit the same fault, and owner threads often surface fixes before the manufacturer documents them.
When to stop and call the manufacturer: if the fix needs the base opened, the motor or control board touched, or any tool beyond a screwdriver — stop. On a unit in this price range, opening it yourself usually voids the warranty, and a warranty repair costs nothing.

Where something genuinely isn’t documented anywhere, I say so instead of filling the gap.
