Switched from a plastic fountain to this and the difference in cleanliness is night and day. Steel just doesn't get that slimy film plastic does, so I'm scrubbing way less often.

The sensor-driven version of the fountain, for a cat who only drinks when something is actually happening.
- 304 stainless steel bowl and reservoir, the same non-porous surface as the rest of the Water Office line.
- Motion sensor wakes the pump when a cat approaches, then lets it rest, quieter and gentler on the pump long-term.
- USB rechargeable, so it can sit anywhere in the house without hunting for an outlet.
- Wide, low bowl designed around a cat's whiskers, not a human's idea of a water dish.
- Capacity: 3.2L reservoir
- Material: 304 stainless steel body
- Power: USB rechargeable, 5V
30-Day Cat Approval Trial. If the sensor doesn't earn its keep, return it within 30 days.

steel never gets that gross biofilm plastic bowls get
Holly C. 5/5 Verified
Cleaning is so much easier now that it's steel instead of plastic. No scrubbing out weird residue anymore, just a quick rinse and it's good.
Daniel P. 5/5 Verified
no more cord fuss, moved it three times already
Bella R. 5/5 Verified
3.2L tank lasts almost two days with one cat
Rebecca K. 5/5 Verified
Really solid fountain, the steel construction feels premium and my cat has taken to it immediately, drinking way more than she used to.
Noah W. 5/5 Verified
My cat has always been particular about her water, she'd sniff at her old bowl and just walk away half the time. This fountain changed that almost immediately, I think it's a combination of the steel bowl staying cleaner and the wide shape keeping her whiskers from touching the sides. The motion sensor is a nice touch too, it means the pump isn't just running constantly, it wakes up when she approaches and quiets down when she's gone, which feels a lot gentler on the whole system long term. Being rechargeable via USB was a bonus I didn't expect to care about but ended up loving, I can put this anywhere in the house without worrying about outlet placement. The 3.2L reservoir holds enough that I'm only refilling every couple of days even with regular use. This has genuinely improved how much water my cat drinks daily, which was the whole point of buying it.

This has been a great upgrade from our old fountain, my cat drinks noticeably more now that the water actually looks appealing to her.
Kaitlyn R. 5/5 Verified
We'd been through two plastic fountains before this one and both ended up with that filmy buildup no matter how often we cleaned them. The stainless steel bowl on this one has completely solved that problem, it just wipes clean and stays looking new. The motion sensor is the feature that really won me over though, it wakes the pump up when my cat approaches and lets it rest otherwise, so it's not constantly running and wearing itself out. Being rechargeable meant I could put it on a side table instead of being stuck near an outlet, which opened up way more placement options in our small apartment. My cat took to it within a day or two, she's much more interested in drinking from this than she ever was with the plastic one. Worth every penny if you're tired of scrubbing grime off a fountain every week.

The fountain performs great and my cat loves it, but the delivery timeline was rough, took way longer than the estimate given at checkout.
Luna R. 3/5 Verified
This was an upgrade from a much cheaper fountain that kept building up a weird film no matter how often I cleaned it, and the steel here has completely fixed that issue. The sensor feature genuinely surprised me, I didn't expect it to work as well as it does but it wakes up reliably every time my cat walks up and shuts off again a minute or two after she leaves. That alone seems to be extending the life of the pump since it's not running nonstop all day. Being USB rechargeable meant I didn't have to keep an outlet free near where I wanted to place it, which made setup way more flexible than our old plugged in fountain. The bowl itself is wide and shallow so her whiskers stay clear, and she's noticeably more into drinking from it than she ever was before. Really happy with this purchase, the build quality feels a step above anything plastic.
Aria T. 5/5 Verified
I did a lot of research before buying a fountain because our cat has always been finicky about her water source, often preferring to drink from the bathroom faucet over her bowl. This one solved that almost entirely. The stainless steel surface stays clean without the slimy buildup we always dealt with on plastic, and the motion sensor means the pump only runs when she's actually there, which feels smarter and quieter than a fountain running all day regardless of use. Being rechargeable through USB meant I could set it up on a counter away from any outlet, which made finding the right spot for her so much easier. The wide, low bowl shape seems to have made a real difference too, she's not pawing at the water or hesitating like she used to with her old dish. It's been a couple months now and she still checks this fountain multiple times a day, so I'd call that a win.

sensor actually works, pump kicks on the second she walks up
Violet J. 5/5 Verified
3.2L reservoir keeps up fine for our one cat, only need to refill every couple of days. Wish I'd upgraded from our old fountain sooner honestly.
Michael W. 5/5 Verified
After years of plastic fountains that always seemed to get grimy no matter how often I cleaned them, switching to this stainless steel one has been such a relief. It wipes clean in seconds and never develops that cloudy film plastic always did for us. The sensor feature works better than I expected, it consistently picks up when my cat walks over and starts the pump, then lets it idle when she's not around, which seems like it'll help the pump last much longer than one running all day nonstop. Not being tied to a cord means I've been able to move it around the house depending on where she wants to hang out that week, which has been surprisingly convenient. The bowl is wide and shallow enough that her whiskers never brush the sides, and she's clearly more comfortable drinking from it compared to her old dish. Genuinely one of the better pet purchases we've made this year.
Grace P. 5/5 Verified
Being rechargeable means I could put this wherever made sense instead of wherever the outlet was. Moved it to the hallway and haven't looked back.
Nathan W. 5/5 Verified
Sensor mode means it's not just running the pump 24/7 which I like, feels gentler on the motor and it's basically silent when nobody's nearby.
Sarah G. 5/5 Verified
The motion sensor picks her up from a few feet away and starts the pump right on cue, it's a nice little bit of tech that actually works.
Chloe M. 5/5 Verified
The motion sensor is genuinely clever, it wakes up the second my cat walks near it and goes quiet when she wanders off. Feels like it's actually saving the pump instead of grinding away all day.
Madison N. 5/5 Verified
My cat is a bit of a princess about her water and this stainless bowl seems to have won her over completely. She used to ignore her old dish half the time.
Aurora H. 5/5 Verified
steel bowl stays spotless, no more slimy buildup like our old one
Savannah R. 5/5 Verified
Really like this fountain, only wish the recharge held up a bit longer between charges since I'm plugging it in every few days.
Natalie M. 4/5 Verified
quiet, clean, cat approved within a day
Penelope R. 5/5 Verified
Charging it is easy, just USB into any outlet, and it holds a charge long enough that I'm not constantly plugging it back in.
Ryan R. 5/5 Verified
Great build quality but the pump makes a faint click each time the sensor triggers it on. Not loud, just noticeable in a quiet room.
Kelly H. 4/5 Verified
love that it rests when nobody's around, feels smart

so much easier to keep clean than our plastic fountain ever was
