Cat water fountains · Choose by your needs
If you need both a stainless-steel drinking surface and rechargeable operation, Catit PIXI UV-C #43761 supports sensor or timed battery flow; PETLIBRO Dockstream 2 Cordless has continuous or sensor battery flow; PetSafe HydroSphere Cordless uses battery-triggered flow. These are not the same mode, and none is an all-steel water path just because its drinking surface is steel.
Comparison updated 29 October 2026.
| Model | Exact model | Battery flow and capacity | Surface/care tradeoff |
|---|---|---|---|
| Catit PIXI Stainless Steel UV-C Fountain 43761 | Catit PIXI UV-C #43761 | 5 L; battery sensor or timed, not continuous | Stainless tray plus wet components; only stainless parts are dishwasher-safe. |
| PETLIBRO Dockstream 2 Smart Cordless Fountain PLWF116 / 6236116 | PETLIBRO Dockstream 2 Cordless PLWF116 | 3 L; battery continuous or sensor | Steel tray over ABS tank; dishwasher permission unresolved. |
| PetSafe HydroSphere Cordless 60 oz PWW00-18313 Black / PWW00-18311 White | PetSafe HydroSphere Cordless PWW00-18313/18311 | 1.7 L; battery motion or USB continuous | Steel tray and splash guard; pump hand-washed, base kept dry. |
Choose it when: The exact #43761 manual documents a rechargeable plan for a steel-surface fountain and specifies its sensor/timed battery choices.
The limit: Continuous operation requires a compatible adapter; battery mode cannot be treated as continuous circulation. The tray is only one part of the wet assembly.
Choose it when: The exact PLWF116 is a rechargeable fountain with a stainless-steel drinking tray and continuous or sensor flow documented on battery.
The limit: The maker's runtime claim is limited to one pet in sensor mode. The exact U.S. guide conflicts with the current product page on tray dishwasher use, so permission is not confirmed.
Choose it when: The exact U.S. Cordless configuration has a stainless-steel tray and rechargeable motion-flow plan, so it meets both material and power conditions.
The limit: Battery operation is not continuous flow; USB power is required for continuous circulation. Do not transfer the exact Cordless claims to a different HydroSphere finish/configuration without checking its own record.
PETKIT EverSweet Max Cordless has a nonstick-coated steel tray, which is a different supplied surface from bare stainless steel and is not included in this steel-only answer. See the coated-steel page if that is what you want.
These models use different tanks and pumps. If dishwasher use is essential, confirm the exact component's permission separately; for example, Dockstream 2 evidence conflicts, whereas the HydroSphere's named bowl, tray and guard have top-rack directions.
No. Dockstream 2 documents battery continuous flow; Catit #43761 documents battery sensor/timed modes; HydroSphere battery flow is motion-triggered. Their plugged-in modes differ.
No. Each fact record identifies additional tank, pump and wet components. The steel answer applies to the supplied drinking surface.
No. The P4115 coating is classified separately. If you want nonstick-coated steel, use the coated-steel answer rather than this surface condition.
