Cat water fountains · Choose by your needs
When the fountain must be both rechargeable and app-controlled, four exact configurations match. PETKIT EverSweet Max Cordless P4115 and Max 2 UVC P4116 document Bluetooth app use with battery interval flow; PETLIBRO Dockstream 2 Cordless and its Starter Pack support battery sensor or continuous flow with direct dual-band Wi-Fi and one-pet records. Bluetooth is not direct Wi-Fi, and the PETKIT guides require a compatible master for remote interconnection.

| Model | Exact fountain/package | Battery and app arrangement | Important limitation |
|---|---|---|---|
| PETKIT EverSweet Max Cordless EverSweet Max Cordless P4115 | PETKIT EverSweet Max Cordless P4115 | Battery interval plan; Bluetooth app activity records and settings | Guide baseline is 25 seconds per hour; coated tray is hand-wash only; no direct Wi-Fi is documented. |
| PETKIT EverSweet Max 2 UVC EverSweet Max 2 UVC P4116 | PETKIT EverSweet Max 2 UVC P4116 | Battery interval plan; Bluetooth app and energy management | Guide baseline is 25 seconds per hour; app connection is not direct Wi-Fi; UVC is included in this exact package. |
| PETLIBRO Dockstream 2 Smart Cordless Fountain PLWF116 / 6236116 | PETLIBRO Dockstream 2 Cordless PLWF116 | Rechargeable sensor or continuous plan; app, dual-band Wi-Fi and single-pet records | The up-to-30-day claim is for one pet in sensor mode, not continuous flow. |
| PETLIBRO Dockstream 2 Cordless Starter Pack PLWF116 Starter Pack with PLSS106 shield | PETLIBRO Dockstream 2 Cordless Starter Pack | Same PLWF116 battery, app and direct dual-band Wi-Fi setup | The package adds the PLSS106 shield and filter refills; it does not create a different app or pump system. |
Choose it when: The exact P4115 page and guide document app-linked activity and a rechargeable interval plan, so this is a cordless app choice with a nearby Bluetooth workflow.
The limit: Its records describe frequency and average duration, not measured milliliters or individual cats. The current U.S. FAQ prohibits dishwasher cleaning, and remote interconnection requires the compatible PETKIT master arrangement.
Choose it when: The exact P4116 page documents app control, while its model-specific guide documents the rechargeable interval plan and identifies Bluetooth rather than direct Wi-Fi.
The limit: The guide separates battery intervals from wired continuous flow. Remote interconnection depends on a compatible PETKIT master and its setup conditions; the product's motion-sensor advertising is not enough to infer a battery sensor mode.
Choose it when: The exact PLWF116 product and guide document app setup, direct 2.4/5 GHz Wi-Fi, one-pet records and a rechargeable plan with sensor or continuous flow.
The limit: Calibrate the empty base for the one-pet record setup. Multi-cat identity is not established, and the maker's runtime statement is conditional on sensor mode and one pet.
Choose it when: The exact Starter Pack listing includes the rechargeable PLWF116 fountain and documents the same app, dual-band and one-pet setup, while identifying its added shield and filters.
The limit: Choose this package only if its included shield and filter supply are useful. It retains the same one-pet record limit, conditional battery claim and unresolved dishwasher guidance as the PLWF116 fountain.
The P4115 and P4116 connect to the PETKIT app by Bluetooth; their exact guides describe a compatible PETKIT master-device arrangement for remote interconnection. Their fountain entries do not list direct Wi-Fi bands. The Dockstream 2 PLWF116 products document direct dual-band Wi-Fi. If remote access or a particular router band is essential, verify the compatible network and master setup rather than treating all app connections as equivalent.
The PETKIT guides document battery interval dispensing, with a baseline of 25 seconds each hour; their wired continuous/intermittent choices do not transfer to battery mode. The Dockstream 2 Cordless plans document sensor or continuous battery operation. Its up-to-30-day claim is specifically for a fully charged unit, one pet and sensor use, not continuous circulation.
The Dockstream 2 Cordless Starter Pack contains the same PLWF116 fountain as the standard package, plus the listed shield and filter supplies. Those additions do not change its app functions, flow modes, one-pet record setup or runtime conditions. PETKIT P4116 includes UVC hardware, but that is separate from its app and battery schedule.
No. PETKIT P4115 and P4116 use Bluetooth app connections; remote interconnection needs a compatible PETKIT master arrangement. The exact Dockstream 2 PLWF116 products support direct dual-band Wi-Fi.
No. The P4115 and P4116 guides document battery interval schedules. Dockstream 2 Cordless documents continuous or sensor operation on battery; its up-to-30-day statement applies only to one pet in sensor mode.
No. It contains the same PLWF116 fountain, with the listed shield and filter supplies. The app and one-pet record setup remain the same.
Catit PIXI Smart #43751 is an outlet-powered app-controlled option; PETKIT EverSweet Ultra P4117 is a plug-in camera-profile system. They do not meet the rechargeable condition, so use the broader app-control answer if an outlet is acceptable.
