oneisall Wireless Cat Water Fountain, 3.5L/118oz Battery Operated Pet Drinking Fountain Stainless Steel, Running Water Dispenser Fountains for Cats, Cordless&Rechargeable with Motion Sensor(Hale 3.5L)

I haven't written a review in quite a long time, but I'm SO impressed with this fountain that I knew I had to take the time to do it. Firstly, let me say that I have 2 Eufy fountains and my kitties love them, and so do I. There's no motor, and it's super silent. My cats drink water like crazy from them. Here's the thing. I decided randomly to purchase a wireless fountain to have more flexibility in placement. I picked this one and so far, I'm really glad I did. While it does have a motor, so far it operates perfectly, and after only having it for one week, I took it apart and cleaned the motor assembly just to see how it went. It's definitely upgraded from the older motorized fountains I used before discovering Eufy. It wasn't yucky at all. Also, the filter had lots of cat hair, so it's definitely doing a great job as well. I'm not saying anything bad about the Eufy fountains' functionality because they're fabulous. I DO wish the filters didn't cost a fortune, and now that I've bought this fountain, I really wish they had wireless capabilities. Something else I LOVE about this wireless fountain is that the reservoir is stainless steel (Eufy is plastic) and keeps the water much colder. I have it set on motion sensor and it's perfect. I believe the flow starts when you or the kitties get within 3 ft of it. I love that it saves the charge instead of running constantly. My cats and I love this fountain. I will need to give it more time to see the longevity of the motor before purchasing more and switching entirely from my Eufy ones, but so far, it's amazing. It was so easy to set up, it runs silently, and I can place it wherever I want. It's great not having to worry about an electric outlet. I decided to do a little test today with my Willy boy and brought a Eufy on the table next to this one. My 4-second video shows the result, and Eufy wasn't the winner. That's why I needed to post this review! Oh, I had to come back to add. It comes with a nice, long, high-quality charging cord, AND a charger brick! Whoa! Two more things I forgot to add: I love the change filter light that comes on when it's dirty. Very helpful. I only had to recharge it after 3 WEEKS of using it in motion detection mode. Very impressed!

The Oneisall Wireless water fountains work great and are easy to clean and keep free of contaminates. I've been using two of these fountains for about six months and had the blue water level light quit working on one of them. Customer service was exceptional - they answer their phone and quickly respond to emails. I received a replacement within a few days.

So far I like this fountain more than my cordless petlibro docstream. I needed a second fountain since I got a second cat and didn't want to spend a lot on another fountain. It works great, love the cordless feature, is pretty quiet and has multiple settings. I love that this is more dishwasher friendly than my petlibro so it's easier to clean and more hygienic. I also love that the battery power is on the top of the fountain making it easy to charge and it holds a little bit water on the top tray even when the fountain is not running so cats always have access to water, I do love my petlibro fountain but I hate that when the charge runs out my cat doesn't have access to water. Can't speak on the durability yet since I've only had it two weeks but so far so good.

Update 6/8/26 - after using this wireless water fountain for a year, I can say that this is my least favorite one of the 3 that I own. Cleaning is quite a chore - you have to be very careful not to get all the electrical connections wet ÀND it’s sharp edges on the stainless steel tray are very dangerous when disassembling. I have sliced my finger more than once when trying to pry the tray off. There are 4 electrical connections that you need to avoid getting wet which is difficult when trying to fully clean the unit. I would NOT recommend this product. I own a motor-less water fountain which is very easy to clean. New update: Be careful when cleaning - the stainless basin has sharp edges that can cut your finger when trying to remove it. I have 3 wireless fountains and this brand/model is the hardest to clean. There is no way to clean the spigot as it is incorporated into the top power module. You also have to be very careful to not get the cable connections wet (the power module plugs into the top of the plastic basin and the pump plugs into the basin from the bottom). Water can be easily splashed onto the connections. Stopped working after 6 months. Purchased in April 2025. It worked fine until October 2025 and then the pump wouldn’t start even after charging. The fountain had been cleaned and charged weekly. I had already purchased a replacement pump to have on hand after reading reviews that they could go bad but the new pump didn’t work either. It gets power, as indicated by the LED light but does not operate. I can only assume that the main power control module is faulty. I reached out to the Oneisall customer support email and they want me to send a picture?!! of my problem. I’m not sure how a picture or even a video is going to show anything even if I did have the ability to take and send a video. I have had several cat water fountains in the past 4 years and none of them stopped working after only 6 months! I’m very unhappy and disappointed with this Oneisall Wireless Cat Water Fountain and would NOT recommend it. *Update 11/11/25- Oneisall Customer Service reached out again and said they would send a replacement part. Hopefully this will solve the issue. 11/13/25 - they sent me a new water fountain, not just the control module. I actually like the new one better as it’s smaller than the original. There is a 2 year warranty on the product. Very good customer service. I’m changing my rating to 4 stars although it shouldn’t have malfunctioned after only 6 months. I’m very satisfied with my customer service experience.

After trying several pet fountains, this oneisall Wireless Cat Water Fountain has become one of my favorites! I originally switched from the Veken model to this one because I needed something cordless—my curious kitten loves to chew on wires—and this fountain solved that problem perfectly. No cords, no mess, and total peace of mind! I love the three mode options, especially the motion sensor mode, which only runs when my kitten approaches. It’s a genius feature that helps preserve battery life and keeps the water fresh throughout the day. The thoughtful low-water, low-battery, and filter indicators are also a big plus—no more guessing when it’s time for maintenance or refills. The design is sleek and modern; I really like the white exterior paired with the stainless-steel interior and lid, which keeps things clean and hygienic. My only small wish is that the filter holder were also stainless steel, like the Veken fountain—it would make it feel even more premium. I also miss the flower-style fountain head from my previous fountain since my kitten loved having multiple flow angles to drink from. Still, this is an excellent fountain overall—quiet, functional, and beautifully designed. If oneisall ever combines this cordless, feature-rich setup with a flower-style flow option, it would be the perfect cat fountain.

Over the past 10 years I have owned an assortment of water fountains for our cats. Each one of them had a some good features and some bad features. This one is terrific. The cats like it, it is easy to clean, the water is purified and I don’t have to fill it every few days. I give this 5 stars - no question about it. I had a problem with my cat who liked to play with the water and splashed it on the floor under the metal bowl. The feet on the bottom of the bowl weren’t high enough to allow any air circulation to dry the pool that collected beneath the device, so I bought some plastic feet and raised it up. Problem solved.

My cat likes this better than his old one with the high-arc spout (guess he didn't like getting his whiskers wet). Also this one seems to have a better/easier recharge process; no issues at all with starting up again after recharging the battery. Easy to fill & clean, quiet operation, promises to last at least a year.

This would be essentially perfect if it worked consistently. But there have been a number of times in the 9 months I've had this fountain that it just randomly stops working. The only way to tell is to be mindful enough to notice that the internal light doesn't turn on when you walk by or when the cat comes to drink from it. There don't seem to be any tricks to getting it working again. Turning off and back on, plugging in the power, disconnecting the motor and reconnecting, changing from motion sensor to timed function, taking the entire motor apart and cleaning thoroughly...none of these made it work again. It seems to start working again as spontaneously and inexplicably as it stops. This makes it extremely unsafe to use in the hot summer, if this is your cat's only water source. Additionally, tiny rust spots started forming in the base within 3 months. They can be scrubbed almost all the way off, but clearly that effects the safety & flavor of the water. This model is designed so that if filled to the max line, the motor's plug is submerged. I'm certainly no pro, but it seems to me this is a design flaw, and may contribute to the spontaneous malfunction issue. I do not recommend.

Just wonderfull 👍👏 love it ,wofks judt perfect.my cats and fogs liked it ,very eady to use and very practical. Thank hou Amazon.sa😍👍👏👏

Very happy with this cat water fountain. My cats love to drink from it and it's very easy to clean and maintain. I'm a cat sitter and I've seen a lot of different fountains in my clients' homes and I think this is defintely one of the easiest to put together. I like that you can change the setting from proximity to timed as my cats were initially a bit spooked by it coming on when they approached, evn though it is pretty quiet. The charge lasts a good while and it holds plenty of water. I usually charge and refill it after a week. I think it can last a little bit longer (I have two cats) but I don't think it's good for the pump if you let the water run out so I just do it weekly to be safe. I've had it almost a year now and the pump just failed. I notified the seller and they sent me a replacement straight away. Very pleased with the customer service too.

lovely fountain. it’s so quiet and i love that you can have it on through 3 modes: 1) sensor, 2) 30second activation every 30-minutes, and 3) always on (if plugged in). i got this fountain to replace the AONBOY because it was plastic and i noticed my kitten always drank water from the basin not the stream. this one had a wide basin and was perfect for her! i was really sold on the fact that water always remains in the basin even if the stream isn’t on, which is important in case the battery dies or your power goes out - your cat should still have a place to drink! i also like how compact this fountain is. it doesn’t take up so much space, yet has a capacity of 3.5L. i initially thought my kitten would get scared if the stream came on through motion sensor, so i kept the fountain plugged in for the first 3 days to get her used to the new fountain. i still kept her old fountain nearby, but off, as well as a regular bowl if she was to nervous to drink from the new fountain. it took her about 3 days to finally drink from it confidently and she wasn’t spooked by the stream coming on as she approached! i love that the fountain is stainless steel! it means it won’t hold on to odour and that it’s more difficult for bacteria to proliferate! the water also stays colder longer :). it was great to see that the fountain also cane with two extra filters! the wireless aspect was not one of the original motivators for my purchasing of this fountain, but it’s actually come to be one of my favourite features. i love that the battery lasts 60 days. that’s phenomenal. my kitten drinks water much more frequently now!

Tengo 5 meses con el y no he tenido ningún problema, me encanta, es muy útil porque no se tiene que estar limpiando diario, y la fuente llama la atención y se acerca para tomar, no hay que estar precupado porque se quede sin agua, porque el mismo dispositivo te avisa. El único incoveniente es que no es fácil encontrar en línea los filtros, sólo hay un proveedor que te vende en cantidades muy grandes :(

It was working good until it wasn’t. After 3 months connecting the pump was problematic, it wasn’t working properly. It died completely after 9 months of use. I am disappointed.
