20 facts in comparison
PETKIT EverSweet Solo 2 vs PETKIT EverSweet Solo SE
These two are the same fountain with different brains. PETKIT sells the Solo 2 and the Solo SE at much the same size, in much the same shape, holding within a couple of hundred milliliters of each other, and the two differences between them are both about electronics rather than about water.
The first is app control. The Solo 2 connects to PETKIT's app over Bluetooth, and the useful part of that is knowing the water is low or the filter is due without standing over the bowl. It is a same-room convenience: with no Wi-Fi in the fountain, the app cannot tell you from work or from a weekend away whether the pump is still running. The Solo SE does none of it. It is a pump, a filter and a switch.
The second is flow. The Solo 2 offers three modes and the SE runs one. In practice this is less about a cat preferring a particular stream than about noise and duty cycle: an intermittent mode runs the pump less, which means less hum in a quiet room and longer between filter changes. Some cats do prefer constant movement, and for those the single mode is not a limitation at all.
What does not differ is most of the product. Both are shaped the same way to keep whiskers clear of the edges, both need taking apart and washing on the same sort of schedule, and both live or die on whether their filter gets replaced. A fountain's real running cost is filters and effort, and this pair shares both.
That makes the decision unusually narrow. You are paying for notifications and a choice of flow, and nothing about the water itself changes.
Editor’s note
My skepticism about connected pet gear stops at the water bowl. A feeder that fails is a missed meal. A fountain that fails silently is a cat that drinks nothing, and the alerts on the Solo 2 are aimed squarely at that. It is a better justification for connectivity than most of this category manages.
The app still carries the usual caveats. It expects an account, and the value it provides depends on notifications staying reliable enough that you leave them switched on. If you already ignore alerts from three other apps, this one joins them and the Solo 2 quietly becomes an expensive SE.
The flow modes are more marginal than they look. Cats are individual about moving water and neither model lets you audition its behavior before buying. A cat that already drinks from a running tap will take to either. If yours is wary of noise, the quieter intermittent setting on the Solo 2 is a real if small advantage.
Both need the same weekly clean, and neither survives being ignored. No app changes that part.
Head-to-head points: every spec is scaled between these products only, so a product can score high here and modestly on its own page, where the VS Score measures it against the median of its class.

What reviewers say
The bottom line
Where the fountain sits decides this. Out of sight (a spare room, an upstairs landing, a house you leave overnight), the Solo 2 earns its app by telling you about a problem you would otherwise find late. In the kitchen, where you pass it every day, the Solo SE is enough, and it keeps another appliance off your phone. For a single cat in a busy household the SE does the same job for less, and the difference covers a year of filters. For anyone who travels, or for a multi-cat home where an empty bowl becomes urgent quickly, the Solo 2's alerts are the difference between noticing tonight and noticing on Sunday.
