Summary
WIRED's top pick after testing multiple fountains — cordless for 30 days, app-connected, and features a wireless pump that makes cleaning dramatically easier. Tracks your pet's water intake over time so you can spot health changes early.
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
- Cordless for up to 30 days on battery, or can run plugged in
- App monitors water intake, water levels, and battery life with daily/historical comparisons
- Wireless pump design makes disassembly and cleaning much easier
- Four-layer filtration: nonwoven fabric, activated carbon, ion-exchange resin, high-density sponge
- Detachable basin for easier cleaning
- Quietest fountain tested across 15 models in Good Housekeeping's evaluation
- Stainless steel bowl is dishwasher safe for easy cleaning
- 3.2L capacity handles multiple pets for several days
- Generous 6-foot cord for flexible placement
- Comes with four filters included to start
Cons
- Plastic basin is less hygienic than stainless steel or glass
- Requires more frequent cleaning than stainless steel alternatives
- Ongoing filter replacement costs
- 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
This is the fountain to get if you want the full package: smart features, easy cleaning, and cordless flexibility. WIRED tested it head-to-head against the competition and it came out on top.
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.
