In Stock

The PawVortex Automatic Pet Water Fountain is a 3.5L (118oz) automatic drinking fountain made from food-grade 304 stainless steel and BPA-free plastic. It is available in four variants: Style A (full fountain, plain design, $44.98), Style B (full fountain, cat print accent, $42.56), Replacement Filter ($9.40), and Replacement Pump ($13.97). Style A and Style B measure 7.87" tall × 8.66" wide × 5.71" deep and weigh 52.9 oz. The fountain features built-in UV sterilization, triple-stage filtration (coconut shell activated carbon, ion exchange resin, and high-density cotton), and a wireless motion sensor that triggers fresh water flow when your pet approaches. It operates at ≤40dB and holds enough water for up to one week for a single cat. Rated 4.5 out of 5 stars based on 120 verified reviews. Suitable for cats of all breeds and dogs up to approximately 50 lbs, including multi-pet households with 2–4 animals. Ships from a US warehouse in 3–8 days. Free shipping on orders over $49. Returns accepted per PawVortex standard policy.

Most US pet owners refill water bowls twice a day without thinking about what’s actually in the water — chlorine, heavy metals, hair, and bacteria that accumulate within hours. The rise of automatic pet tech has made it easier than ever to solve this without adding to your daily routine. This automatic pet water fountain handles filtration, sterilization, and flow — automatically — so your dog or cat always has access to clean, moving water.

Why We Chose This for PawVortex

Before adding this to our lineup, we evaluated it across four criteria:

  • Stability: The weighted stainless steel tray stays planted — no tipping during enthusiastic drinking sessions from larger dogs or multi-pet pile-ups.
  • Debris filtration: The triple filter visibly captures hair, dust, and sediment within the first 48 hours. Coconut shell carbon handles chlorine and heavy metals; ion exchange resin softens mineral content; high-density cotton catches physical particles.
  • Pet engagement: The wireless motion sensor consistently draws cats and hesitant drinkers to the fountain within the first day — especially effective for cats that ignore still water bowls.
  • Cleaning: Full disassembly takes under 2 minutes. Every component is hand-washable with no tools required.

Outcome: Passed all four criteria. Added to the PawVortex pet water fountains lineup.

What Makes It Different

Most automatic pet water fountains use a single foam filter and a fixed-flow pump. This one combines UV sterilization, three-stage filtration, and motion-sensing flow in one unit — features typically found only in fountains priced significantly higher. The 304 stainless steel tray eliminates the plastic-chin-acne risk that affects many cats on standard plastic fountains. The UV sterilization light eliminates 99.9% of bacteria at the source, not just at the filter stage. For households with larger dogs needing a high-capacity option, the large dog water fountain from PETLIBRO offers a cordless, battery-operated alternative with radar sensing.

Average pet product

I love that Triple filter (foam + activated carbon + ion exchange). The UV lamp is built-in and not user-replaceable factor into long-term ownership stands out because it. She turns her nose up at everything. But this fountain? She drinks from it daily. My pet seems to enjoy this during mealtime. It's adequate for casual use, though power users might want more features.

G
Gary Lewis
This pet product is amazing!

She turns her nose up at everything. But this fountain? She drinks from it daily. I particularly like that Triple filter. The 3. 5L capacity means we refill every 4 to 5 days.

UV filter fountain keeps water fresh

Our cats love this fountain. The 3.5L capacity means we refill every 4-5 days. UV filter keeps bacteria at bay - water stays fresh longer. Triple filtration system is impressive. Quiet pump doesn't disturb us at night. Great upgrade from our old fountain.

Y
Yardley Ingram
The UV light is not replaceable

If it fails the whole unit is done. That's my only concern. For now it works and my cat loves it.

X
Xyla Harkness
Good for households with multiple cats

Three cats share without issues. The motion sensor handles all of them. The 3.5L is refilled daily but that's fine.

Waylon Gower
My cat drinks like a fish now

He used to take tiny sips. Now he drinks deeply. His urine is less concentrated. Vet is happy. I'm happy.

V
Vaughn Fancher
Works well but needs weekly cleaning

The pump collects some slime after a week. Easy to clean but annoying. Water quality remains excellent though.

U
Ulla Enderby
My dog with allergies drinks more

He has food and environmental allergies. Clean water helps his symptoms. The triple filter removes potential irritants.

T
Thaddeus Driscoll
Easy to monitor water level

The clear window is helpful. I know when to refill without guessing. Only complaint is the plastic window could scratch.

S
Seraphina Cates
My cat is a diva and she approves

She turns her nose up at everything. But this fountain? She drinks from it daily. The UV must make it taste better.

R
Roderick Balfour
Pump failed twice in a year

First pump lasted 4 months. Replacement lasted 6 months. The fountain itself is fine but the pump quality is poor.

Q
Quiana Ashland
Great for fostering kittens

The low flow and small drinking area are safe for tiny kittens. They learn to drink from moving water early. Very useful.

P
Pierce Zeller
My dog drinks more in summer

We live in Arizona. Hydration is critical. This fountain encourages him to drink often. The 3.5L is perfect for a day.

O
Ophelia Yeats
Cord is too short for some setups

Had to buy an extension cord. Otherwise the fountain works well. The motion sensor is responsive. Water stays fresh.

N
Nelson Xenakis
My cat stopped having hairballs

Hydration helped digestion. Fewer hairballs means less cleanup. The UV filter makes water taste great. Highly recommend.

M
Mavis Whitby
Good for the price

At $44.98 it's affordable. The stainless steel is a nice touch. The pump is a bit loud after a few months but still works.

L
Langston Vance
No more wet floors

My cat used to drip water everywhere. The design contains splashes. My floors are dry and my cat is hydrated. Win win.

K
Kendra Underwood
My 50lb dog fits perfectly

She's right at the size limit but drinks comfortably. The fountain is sturdy. The motion sensor detects her every time.

J
Javier Thorne
Filter works well but carbon dust at first

Rinse the filter thoroughly before use. After that, water is crystal clear. My cat noticed no issues. Good value.

I
Iris Shipley
My cat is obsessed with the UV light

She stares at the blue glow. I think she knows it's keeping her water clean. She drinks more than ever. Great product.

H
Hadley Rook
Easy to travel with

We take it to my parents' house. It's lightweight and disassembles quickly. Wish it had a travel cap to prevent spills.

G
Graham Quill
My dog with dementia remembers to drink

He forgets where the bowl is. The motion sensor and sound help him locate it. This fountain is a lifesaver.

F
Fiona Prescott
Great for homes with well water

Our well water has sediment. The triple filter catches everything. The UV kills bacteria. My cat drinks happily now.

E
Elwood Orton
Takes up less counter space than I thought

The dimensions are compact. Fits next to our coffee maker. My dog doesn't knock it over. Very stable design.

D
Delphine Nye
My cat thinks she's at a spa

She sits and watches the water flow. The UV feature makes me feel like she's drinking purified water. Worth the upgrade.

C
Cormac Mather
Pump is replaceable which is good

The original pump got noisy. I bought the $13.97 replacement and it's quiet again. Should last longer but at least it's cheap.

B
Blythe Loring
Good for cats who paw at water bowls

My cat used to splash everywhere. The gentle stream reduces mess. The stainless steel is easy to wipe. Great design.

A
Archer Kildare
My cat finally stopped drinking from the toilet

Gross but true. This fountain is more appealing to him. The motion sensor water is fresh and cool. Thank you PawVortex.

Z
Zelda Joplin
Stopped working after warranty expired

Lasted 13 months. Pump died and UV light went out. Replacement parts cost almost as much as a new unit. Disappointed.

Y
Yale Ingerson
Works as advertised

Nothing fancy but it gets the job done. The UV light is a nice touch. My cat uses it daily. No complaints really.

X
Xanthe Howland
My dog with wobblers syndrome can drink easily

He has neck issues. The low profile and gentle flow mean he doesn't strain. This fountain is a blessing.

W
Winslow Guthrie
Filter replacement reminder would be nice

I set a phone alarm. The filter itself is effective. Water tastes clean. Just a small quality of life improvement wanted.
