PetSafe HydroSphere 1.7L Cordless Pet Water Fountain
Put fresh, flowing water where your pet actually wants to drink with the PetSafe HydroSphere 1.7L Cordless Pet Water Fountain. Powered by a rechargeable battery, this automatic water fountain can operate without being permanently connected to a power point, giving you far more freedom to position it around your home. A quiet bubbling flow, motion-activated cordless operation, UVC sanitation and Ion-X™ filtration help provide fresh and inviting drinking water for cats and small dogs.
A Cordless Pet Fountain You Can Put Almost Anywhere
Traditional electric pet fountains need to stay close to a power point. The PetSafe HydroSphere cordless water fountain uses a rechargeable battery, allowing you to place your pet's water in the kitchen, lounge room or another favourite drinking location without running a permanent electrical cord across the floor.
When operating cordlessly, the fountain uses motion-activated water flow to detect when your pet is nearby. For continuous flowing water, simply connect the HydroSphere to power.
Fresh, Flowing Water Encourages Better Drinking Habits
Many cats and dogs are naturally attracted to moving water. The HydroSphere produces a gentle bubbling flow that makes drinking more interesting than water sitting still in a conventional bowl.
Its quiet operation is designed for use inside the home without creating unnecessary pump noise, making it particularly suitable as a cordless cat water fountain or water fountain for smaller dogs.
UVC Sanitation
The PetSafe HydroSphere uses UVC sanitation as water circulates through the fountain, helping maintain fresher drinking water throughout the day.
Ion-X™ Water Filtration
An included PetSafe Ion-X™ filter helps remove impurities and improve the taste of your pet's water, working alongside the UVC system to provide a cleaner and more appealing drinking experience.
Stainless Steel Drinking Surface
The HydroSphere features a stainless steel drinking tray that provides a durable and easy-to-clean surface for your pet. Stainless steel helps resist residue and build-up and does not absorb odours in the same way as many plastic surfaces.
This makes the HydroSphere a practical choice for pet owners looking for an easy-to-maintain cat or dog water fountain for everyday use.
Designed for Easy Cleaning and Refilling
Pet fountains require regular cleaning, so the HydroSphere has been designed to make routine maintenance straightforward.
- Wire-free internal pump allows the bowl to lift away from the base without an electrical cord running through it.
- Removable bowl makes refilling and rinsing easier.
- Dishwasher-safe components include the removable bowl, stainless steel tray and splash guard.
- Splash guard helps keep circulating water contained inside the fountain.
LED Indicators Take the Guesswork Out of Maintenance
Built-in LED indicators provide useful reminders for everyday fountain maintenance, including water level, filter replacement and battery status.
This makes it easier to see when your cordless pet fountain requires attention without repeatedly dismantling or checking the unit.

PetSafe HydroSphere Cordless Fountain FAQs
Is the PetSafe HydroSphere actually cordless?
Yes. The PWW10-18312 HydroSphere contains a rechargeable battery, allowing the fountain to operate without remaining connected to a power point. This gives you much greater flexibility when choosing where to place your pet's water.
How does the cordless HydroSphere fountain work?
When used on battery power, the HydroSphere uses motion activation and starts the water flow when your pet approaches. This helps conserve battery power rather than running the pump continuously when your pet is not drinking.
Can the HydroSphere run continuously?
Yes. If you prefer continuous circulating water, the fountain can be connected to power instead of using the motion-activated cordless mode.
Is the PetSafe HydroSphere suitable for cats?
Yes. The HydroSphere is particularly well suited as a cordless cat water fountain. Its 1.7 litre capacity, gentle bubbling flow and quiet operation provide an inviting source of drinking water without requiring the fountain to stay beside a power point.

Yes. PetSafe designed the 1.7 litre HydroSphere for both cats and small dogs.
Does the HydroSphere filter the water?
Yes. It uses PetSafe Ion-X™ filtration to help remove impurities and improve taste. The cordless HydroSphere also features UVC sanitation to help maintain freshness as the water circulates.
What does the UVC system do?
The built-in UVC sanitation system works as water circulates through the HydroSphere, helping maintain fresher drinking water alongside the Ion-X™ filtration system.
Does the HydroSphere have a stainless steel bowl?
The HydroSphere uses a stainless steel drinking tray, providing a hygienic and easy-to-clean drinking surface for your cat or dog.
Is the HydroSphere easy to clean?
Yes. The detachable wire-free pump allows the bowl to be easily removed from the base. The removable bowl, stainless steel tray and splash guard are dishwasher safe for convenient regular cleaning.
