Summary
WIRED's pick for best cordless stainless steel fountain — fully stainless construction resists bacteria better than plastic, and the rechargeable battery lasts up to 60 days. A visible water level window and three flow modes round out a well-thought-out design.
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.

Cons
- Poorly translated instructions make initial setup confusing

- Higher price point than basic plastic fountains
- Motion sensor inconsistent — often activates on close inspection rather than approach

- Filters must be replaced every 30 days, sold in 3-packs for $10
- At $70-$90, one of the pricier options on the market
Our take
For pet owners who've dealt with chin acne or slimy plastic bowls, going all-stainless is a game changer. The 60-day battery life means you can put this anywhere in the house without worrying about cords.
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.
