The Water Looks Clean. Take The Filter Out.

Pull the filter out of the fountain you have now. If it comes out white, keep the fountain you have. This £53.99 one has no filter at all — what your cat has drunk from drains into a second tank and never goes back up.

#1. It goes in the bowl. A second later, it’s back in the tank.

A filter is a strainer, not a drain. Whatever it catches stays in the fountain, in the same water — and saliva it never catches at all. That water goes round again: tank, pump, spout, bowl, back to the tank. HAPAW doesn’t send it back.

#2. You can rinse it. It comes out the same colour.

The hair comes off. The stain stays. Rinsing washes the surface, but it doesn’t clean everything the filter has trapped inside. That is why the instructions tell you to replace the filter, not wash it and put it back. Every drop your cat drinks is pulled through it.

#3. Two tanks. Used water never goes back up.

3 L of clean water feeds the bowl and moves one way only. What your cat has drunk from drains into a separate 1.35 L tank — on a schedule that runs without you, and the bowl refills from the clean side. You can also trigger it with the button or from the app.

#4. The filter is the part they sell you forever. This one has none.

Most fountains want a new filter every two to four weeks — for as long as you own the thing. There is nothing here to replace and nothing to subscribe to.

#5. Out in seconds. Back in three moves.

The tray and both tanks come away whole and rinse under a tap. Putting it back is fill the tank, set the unit on top, drop the tray in — nothing clips and nothing screws.

What Buyers Keep Saying

Buyer photo

The water keeps moving, and my cat seems to enjoy drinking from it.It’s pretty easy to clean, doesn’t take up too much space, and looks nice in my kitchen.

The water stays looking fresh and clean, which is especially important to me for my cats. It’s easy to use, easy to clean, and my cats took to it right away. Definitely one of the most useful pet products I’ve tried. Highly recommend!

It is quiet and it is running well and we didn’t have to fill it as often as our other ones, it also did not get the slime that we get with the ones that have filters. I liked it so well that I bought two more.

Frequently Asked Questions

A normal fountain runs one tank and pumps the same water back up. This one keeps clean and used water in separate tanks, so what your cat has already drunk from never returns to the bowl.

No traditional filter is needed. The sponge and panel only catch hair and debris — they are not filtering the water, because used water is never recirculated. The sponge is reusable; rinse it periodically. Four spares are included.

The app tells you when it is full, and you can set drainage to run automatically or trigger it manually. For most single-cat homes this is a weekly job.

Yes. There is a version without app control, and the app version runs normally on its own — the app adds monitoring, alerts and drainage scheduling.

A 5000 mAh battery takes over, with more than 20 days of runtime. Plugged in, it charges automatically, so moving it or cleaning it does not interrupt anything.

It runs at about 20 dB. Sensor mode keeps it off until your cat approaches, so it is not running all night.

304 stainless steel. Plastic bowls are harder to keep clean; steel wipes down and does not hold a film the same way.

The spout, the steel tray and both tanks lift out and rinse under a tap. The motor unit is not washable — wipe it with a damp cloth. The black sponge that keeps the water line clear rinses too, and spares come in the box.

Every order comes with a 30-day free trial. Registration adds a second year of warranty on top of the standard one.
