Cat water fountains · Choose by your needs
For battery operation plus dishwasher permission for the supplied drinking surface, compare Catit PIXI UV-C #43761, PETKIT EverSweet Max 2 UVC P4116 and PetSafe HydroSphere Cordless. Each has a documented steel drinking surface, but the permitted parts and battery flow modes differ: Catit uses brief sensor or timed runs, PETKIT documents an hourly interval, and PetSafe uses motion-triggered flow. Dishwasher permission never covers the whole electrical assembly.

| Model | Exact model | Battery plan and permitted surface | Important care limit |
|---|---|---|---|
| Catit PIXI Stainless Steel UV-C Fountain 43761 | Catit PIXI Stainless Steel UV-C #43761 | Rechargeable sensor or timed flow; stainless parts are dishwasher-safe | Continuous flow needs a separate compatible adapter. |
| PETKIT EverSweet Max 2 UVC EverSweet Max 2 UVC P4116 | PETKIT EverSweet Max 2 UVC P4116 | Battery interval: 25 seconds each hour; steel tray permission is part-specific | UVC is supplied; wired modes and battery interval are distinct. |
| PetSafe HydroSphere Cordless 60 oz PWW00-18313 Black / PWW00-18311 White | PetSafe HydroSphere Cordless PWW00-18313 | Rechargeable motion flow; bowl, guard and tray are top-rack safe | Hand-wash pump; keep the base dry. |
Choose it when: The exact #43761 manual documents a rechargeable sensor/timed plan and permits its stainless-steel parts in a dishwasher.
The limit: The adapter for continuous flow is not included, and other wet components need the manual's separate cleaning routine. Do not put the whole fountain in the machine.
Choose it when: The exact P4116 guide names its battery interval schedule and stainless-steel drinking tray; exact cleaning sources permit specified non-electrical surface parts only.
The limit: Do not transfer wired continuous settings or current sensor advertising to the documented battery plan. The direct Wi-Fi band is not established, and electrical parts still need separate care.
Choose it when: PetSafe's exact Cordless guide documents motion-triggered battery operation and permits the bowl, guard and tray in the top rack.
The limit: Continuous flow is a separate USB-powered plan. The pump must be hand-washed and the base is not waterproof or submersible.
The battery-plus-dishwasher set is also the exact battery-plus-steel-plus-dishwasher set. The distinction is still useful: dishwasher permission applies to named steel parts, not the pump, cord or base. Follow the exact care instructions and hand-wash components excluded from machine cleaning.
Catit and PETKIT describe scheduled or sensor battery circulation; HydroSphere uses motion flow on its battery and continuous flow only when plugged in. A dishwasher-safe tray does not extend runtime, and a battery claim does not make the whole fountain washable.
No. The permission is part-specific. Remove only named drinking-surface components; keep the pump, adapter, cable and electrical base out of the dishwasher and follow the exact cleaning manual.
No. Its rechargeable plan is motion-triggered; continuous flow uses the separate USB-powered plan.
No. The surface-and-battery article includes other steel models whose dishwasher permission is unknown or not confirmed. Keep the cleaning requirement selected if it is essential.
