The main trade-off
Multi-Tier combines a larger reservoir and two bowls with wall power. HydroSphere trades that arrangement for a bubbling tray and rechargeable placement.
Quick verdict
Choose Multi-Tier for its two drinking levels and larger reservoir when wall power is available. Choose HydroSphere Cordless for a bubbling tray or outlet-free placement, accepting a smaller reservoir and motion-triggered battery flow.
Choose PetSafe Drinkwell Multi-Tier Pet Fountain PWW00-13708 (Taupe) if
- The upper/lower bowl arrangement is your priority.
Choose PetSafe HydroSphere 60 oz Cordless Fountain PWW00-18313 (Black) if
- You need an outlet-free spot and can recharge it.
- You want the bubbling-tray arrangement.
When the recommendation changes
- You need continuous flow away from power: neither documented setup meets that combination.
- An outlet is available, so cordless placement adds little to your setup.
The differences that matter
| Decision point | PetSafe Drinkwell Multi-Tier Pet Fountain PWW00-13708 (Taupe) | PetSafe HydroSphere 60 oz Cordless Fountain PWW00-18313 (Black) |
|---|---|---|
| Reservoir And Drinking Layout | 100 oz reservoir; upper and lower bowls with a free-falling stream.[1] | 60 oz reservoir; bubbling water through a stainless-steel tray.[2] |
What this changes: Choose the drinking arrangement you want. More reservoir capacity does not establish a refill interval or predict what your pet will use.[1, 2] The better fit depends on your priorities | ||
| Placement And Power Mode | The pump connects to a wall outlet through its inline plug and adapter.[3] | Rechargeable operation uses motion-detected flow; plugged-in operation provides continuous flow.[7, 6] |
What this changes: An outlet-free location favors HydroSphere if you accept recharging and motion-triggered operation. With power available, decide by the drinking layout instead.[3, 7, 6] The better fit depends on your priorities | ||
Best for your routine
Two drinking levels at an outlet-equipped spot
Best fit: PetSafe Drinkwell Multi-Tier Pet Fountain PWW00-13708 (Taupe)
Based on listed features, not comparative testing.
Multi-Tier matches that layout; its wall-power requirement remains part of the choice.
An outlet-free drinking location
Best fit: PetSafe HydroSphere 60 oz Cordless Fountain PWW00-18313 (Black)
Based on listed features, not comparative testing.
HydroSphere supports the location if motion-triggered flow and recharging suit your routine.
Bubbling-tray presentation with power already available
Best fit: PetSafe HydroSphere 60 oz Cordless Fountain PWW00-18313 (Black)
Based on listed features, not comparative testing.
HydroSphere fits that presentation even plugged in. You still give up Multi-Tier’s larger reservoir and two bowls.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
If HydroSphere costs more, outlet-free placement should solve a real location problem, or its tray layout should be one you specifically want. If Multi-Tier costs more, weigh its larger reservoir and two-level arrangement.
There is not enough price history here for a purchase-timing recommendation. Compare current exact-model offers.
Limitations
- This is a manufacturer-document comparison, without hands-on testing of noise, battery runtime, cleaning effort or reliability. No drinking, health or water-quality advantage is established.
- Reservoir capacity does not establish how long either fountain can operate unattended or how often you will refill it.
- HydroSphere’s wall-adapter inclusion is unconfirmed. Current availability and matched live prices have not been established. Follow the supplied operating instructions; this comparison is not a complete setup guide.
Questions shoppers ask
What if I want both two bowls and outlet-free operation?
Neither documented setup combines those requirements. Decide which constraint can change rather than treating HydroSphere as a direct upgrade.
Can the whole fountain go in the dishwasher?
No. Both pumps need separate care. Multi-Tier also excludes its adapter and filters; HydroSphere’s electrical base must only be wiped. Follow each model’s component instructions.
What should I check before setting it up?
Confirm the power connection and follow the fill instructions. HydroSphere needs 5V, 2A USB-A power for charging or plugged-in use; its listed USB cable does not establish that a wall adapter is supplied.
Methodology and sources
Compared drinking layout and power modes, then checked component-care and setup restrictions.
