Summary
The most feature-packed smart fountain available — UV-C antibacterial light, four-layer filtration, motion-activated flow, and app alerts for filter changes and cleaning schedules. Wireless battery lasts several days and the ceramic design is genuinely beautiful.
Good Housekeeping's top-rated fountain overall after testing 15 models — the quietest of the bunch, stainless steel bowl goes in the dishwasher, and the 3.2L capacity handles multiple pets for days. Comes with four filters included.
Pros
- UV-C antibacterial light plus four-layer carbon filtration system
- Motion sensor activates flow when pet approaches, saving battery
- Wireless/battery-powered — no cord needed for placement flexibility

- Stainless steel bowl is dishwasher safe for easy cleaning
- 3.2L capacity handles multiple pets for several days

Cons
- Motion sensor inconsistent — often activates on close inspection rather than approach
- Only suitable for cats and small dogs — not large breeds
- Filters must be replaced every 30 days, sold in 3-packs for $10
- At $70-$90, one of the pricier options on the market
- No visible water level indicator — must estimate by feel or schedule
- Not suitable for large dogs who need more than 3.2L daily
- No smart features or app connectivity
- Filter replacement needed every 2-4 weeks
Our take
If you want the smartest fountain on the market and don't mind paying for it, Petcube's is in a class of its own. The UV-C light and motion sensing are features you won't find elsewhere at this price.
For most dog and cat owners who don't need smart features, the Rellaty is the sweet spot: genuinely quiet, easy to clean, and built from stainless steel at a price that won't hurt. It's the 'set it and forget it' pick.
