PetSafe Oasys 64 oz vs HydroSphere 60 oz Cordless: Which Setup Fits Your Home?

Choose by outlet access and the component-care steps you want to follow. Oasys is plug-in powered; its manual describes routing the cord through the bowl and disconnecting the inline plug before cleaning, with a separately hand-washed pump. HydroSphere can run plugged in or on battery; its wire-free pump lifts out magnetically and is also hand-washed, its bowl/splash guard/tray are top-rack-safe, and its base is wiped with a damp cloth. These instructions do not show which fountain takes less effort to clean.

The buying question

Should you choose the plug-in Oasys, whose cord routes through the bowl and whose pump is hand-washed separately, or the rechargeable HydroSphere, whose wire-free pump lifts out but also needs hand-washing?

Oasys is plug-in powered; its manual describes routing and disconnecting the cord and hand-washing the pump. HydroSphere offers rechargeable battery or plugged-in operation; its wire-free pump lifts out magnetically and is hand-washed, its bowl/splash guard/tray are top-rack-safe, and its base is wiped with a damp cloth.

Quick verdict

Choose PetSafe Oasys Pet Fountain (64 oz) if

  • You specifically prefer the Oasys cord-routing, inline-disconnect, and separate pump hand-washing routine; outlet access alone does not distinguish these fountains.

Choose PetSafe HydroSphere 60 oz Cordless Fountain if

  • You want the rechargeable placement option or the choice of plugged-in continuous flow and battery motion-activated flow; note that HydroSphere’s pump still needs hand-washing.

When the recommendation changes
  • If the fountain will sit where a cord is inconvenient, HydroSphere's rechargeable operation may matter more; check PetSafe's setup and charging instructions for your intended use.
  • If care workflow matters, note that both pumps are hand-washed. Oasys instructions include routing the cord through the bowl and disconnecting its inline plug before cleaning; HydroSphere instructions describe a wire-free pump that lifts out magnetically, hand-washed pump parts, dishwasher-safe bowl/splash guard/tray, and a base wiped with a damp cloth. No comparative cleaning-effort result is available.

The differences that matter

Placement And Power Workflow

PetSafe Oasys Pet Fountain (64 oz)

The selected 64 oz configuration is listed as plug-in powered.[1]

PetSafe HydroSphere 60 oz Cordless Fountain

Rechargeable cordless operation supports placement without an outlet; plugged-in operation is continuous-flow, while battery operation is motion-activated.[2]

What this changes: A fixed location near an outlet suits the Oasys power setup. HydroSphere adds a battery-powered placement option and a different operating mode; its runtime and charging interval are not established here.[1, 2]

The better fit depends on your priorities

Cleaning And Component Workflow

PetSafe Oasys Pet Fountain (64 oz)

PetSafe says the fountain parts may go on the top rack, but the pump must be hand-washed separately. Its manual also says to unplug and disconnect the inline plug before cleaning, route the cord through the bowl and rubber seal during setup, and keep the pump and adaptor out of the dishwasher.[1, 3]

PetSafe HydroSphere 60 oz Cordless Fountain

PetSafe says the HydroSphere pump lifts out of the bowl through a magnetic connection and is wire-free. The pump must be disassembled and hand-washed; the bowl, splash guard, and tray are top-rack dishwasher-safe, while the base is wiped with a damp cloth only.[2, 4]

What this changes: Both pumps require hand-washing. The published steps differ in cord handling and how the pump and surrounding parts are removed and cleaned; use those instructions to compare the workflow with your routine. They do not establish that either fountain is easier, faster, cleaner, or safer to maintain.[1, 3, 2, 4]

The better fit depends on your priorities

Both support plugged-in use, so a fixed spot near an outlet does not distinguish them. Compare the documented component-care steps, or choose HydroSphere if its battery mode is useful.

A buyer who wants a rechargeable fountain option for a location without an outlet, with a choice of battery motion-activated or plugged-in continuous flow.

Best fit: PetSafe HydroSphere 60 oz Cordless Fountain

Based on listed features, not comparative testing.

PetSafe documents both operating modes for HydroSphere; this is a feature-fit choice, not a claim about runtime, noise, or better real-world results.

Limitations

  • The 64 oz Oasys and 60 oz HydroSphere capacities are the selected configurations; the four-ounce difference is not used as a recommendation axis.
  • Cleaning steps summarize manufacturer instructions; no hands-on cleaning-effort, hygiene, or safety comparison was conducted.
  • Pickoryx did not test either fountain hands-on; this is a comparison of the manufacturers' published setup and care instructions.
  • The Oasys manufacturer page also presents 128 oz and 256 oz options; this comparison covers only the selected 64 oz item.

Questions shoppers ask

Can the HydroSphere run without staying plugged in?

PetSafe says the rechargeable HydroSphere can run in motion-activated mode on battery or provide continuous flow when plugged in. The page does not establish how long a charge lasts.

How do the published cleaning steps differ?

Both fountains require hand-washing the pump. The Oasys manual also describes routing the cord through the bowl and disconnecting its inline plug before cleaning. For HydroSphere, PetSafe says the wire-free pump lifts out through a magnetic connection, the bowl, splash guard, and tray are top-rack dishwasher-safe, and the base should be wiped with a damp cloth only. The instructions do not compare cleaning effort.
