The Mijia fountain joins the Mijia ecosystem with app visibility of water level and filter life, built as a pump plus tray. The UAH fountain follows a more traditional appliance approach, emphasising capacity and easy disassembly, with stable output and filtration as the core functions.

Mijia suits owners already using Mijia devices who want unified reminders. UAH suits those who prefer no account binding and value capacity and washing convenience, with longer refill intervals and simpler whole-tank changes in multi-cat homes.

Both share water-path hygiene and filter replacement as the weak point, with the pump and spout the usual places for scale. Smart reminders reduce forgotten swaps but do not replace disassembly, and cordless versions raise charging frequency and battery wear.

Decide whether you need remote reminders and ecosystem links, then whether you will actually take it apart weekly. Drinking volume is a key observation; persistent changes warrant a vet visit, since a fountain only encourages intake.
