Petkit mechanism

Petkit Eversweet has a water re-circulating system the pump is located at the bottom of the inner tank and the water wells up to the top of the tank through the sides and then the water falls through the center opening for re-circulation.  To fill the tank just pour water into the center opening located on top of it. The inner tank of PETKIT pet fountain is removable so you just need to lift it out the base to fill/refill, making it convenient and much easier than carrying the whole unit to the sink. When taking out the inner tank, the pump will turn off automatically.

The concept of this cat water fountain is making any dirt that doesn’t pass through the small center opening (to be re-circulated) to stay on top so you can clean them on the surface, they don’t go to the filter so this way the pump doesn’t get clogged with dirt as seen with other pet fountains. The filtering system ensures purified and good tasting water.

Removable water tank

Petkit Eversweet cat water fountain works in 2 different modes: Smart Mode and Normal Mode. When set on Smart Mode and due to the unique technology equipped with a light sensor and water volume indicator the fountain has the ability to sense day or night, adjusting automatically the frequency of water being welled up. The unit wells up more water in the daytime and less at night. When the unit senses daylight it wells up purifying water every 2 minutes and sends fresh water out for 3 minutes. When it senses night time, the unit purifies water every 2 hours, sending up water for 3 minutes. This uses the energy efficiently since pets don’t drink as much at night.

On the other hand, when Petkit fountain is setup in Regular Mode, the fountain wells up water 24 hours. Regular Mode is especially recommended for pets that need to have access to fresh water at all times, such as cats. When setup on Regular Mode, the fountain needs filter replacement more often.

Filter-Change Reminder & Low Water Indicator

Cat drinking from Petkit Eversweet

Petkit Eversweet cat fountain tells you when it’s time to change the filter so you don’t have to guess when the filter has reached its lifespan. Also, this intelligent pet water fountain has a special sensor that detects when the level of water is too low, showing a blue light alert.

When the water level is low the fountain will turn off automatically to ensure safety. This feature is excellent to avoid burning the pump as it happens with other automatic water pet fountains.

How does the Triple Filter work?

The circularly shaped filter contains 3 materials on the inside and each one has a different function in the filter processing:

  • Mesh Screens: It filters dirt from the water that can go through the center opening.
  • Activated Carbon Filter: Ensures the water is always fresh with a sweet taste.
  • Ion-Exchange-Resin: It filters heavy metal ions in the water to protect the pet’s health.

When using Petkit Eversweet pet fountain in Normal Mode, you need to change the filter every 4 weeks. When used in Smart Mode you need to replace the filter every 12 weeks. The decision of how often to change the filter will depend on the quality of water you want for your cat.

  • The design doesn’t allow certain hair and particles go into the filter located under the tank. Only very small dirt can go through the filter.


  • You can find replacement filters at
  • The water fountain features a sensor that detects daylight and identifies this as daytime. When lack of light it identifies it as nighttime. If you set the fountain in Smart Mode you need to place the fountain in a place with enough light for the sensor to recognize it as daytime because if the room or is too dark the fountain will be automatically set in nighttime mode with less frequency of water re-circulation.
  • It may happen that once you change the filter the remainder is still active. To reset this, you need to press the small dark button at the bottom of the fountain for about 5 seconds. With this the reminder will update the changing.
  • To clean the surface of the water from bigger dirt you can use a fine mesh strainer.


Petkit Eversweet cat water fountain works as advertised in the sense of filtering and re-circulating water to get a fresher and better-tasting water for your cat. Also, this fountain allows you to save energy by recognizing the day from the night and adapting this to the cat water intake. However, the point of having a water fountain is for it to automatically clean the water from hair and other elements and in this case, Petkit doesn’t filter bigger particles like these, only very small like dust or similar.


If your cat’s water bowl doesn’t get too dirty or if you don’t mind screening the water occasionally on the surface the Petkit Eversweet could be a good energy saving choice for you. On the other hand, if you have a cat that sheds a lot or if you notice the water in your cat’s bowl gets dirty very quickly, you may want to look for another alternative.
