A pet water fountain keeps water moving and is simple to refill. Choosing one comes down to tank size, material, noise, how it is powered and how often you are willing to change the filter. This guide compares the ROJECO cat water fountains on those points so you can pick the one that fits your home.
Quick picks
- Compact space: the 2L stainless steel fountain has a 2L tank and a body of 304 stainless steel and ABS.
- Fewer refills: the 3.2L stainless steel fountain has a larger 3.2L tank.
- Two bowls: the wireless pump fountain has a dual bowl design and a 2.5L tank.
- Cord-free: the 3.2L wireless stainless steel fountain runs on a 4000mAh rechargeable battery with a radar sensor.

1. Tank size
A bigger tank means fewer refills. The manufacturer cites an adult cat drinking 240 to 350ml a day, so a full 3.2L tank lasts a single cat roughly one to two weeks. A 2L tank suits one cat or a small space. Top the water up when it runs low and follow the cleaning schedule on the product page.
2. Material
The 2L, 3.2L and 3.2L wireless fountains use 304 stainless steel with ABS, which is easy to wipe clean. The wireless pump fountain is made of ABS and PC. Our guide Stainless Steel vs Plastic Water Fountains goes through the differences.
3. Noise
The manufacturer lists the 2L and 3.2L fountains at 20dB or below, the pump in the 3.2L wireless fountain at less than 20dB, and the wireless pump fountain at down to 30dB. If the fountain sits in a bedroom or a quiet living room, compare these figures.
4. Plug-in or wireless
The 2L, 3.2L and wireless pump fountains run from a 5V adapter. The 3.2L wireless fountain has a 4000mAh lithium-ion battery rated for up to 50 days of standby, measured at 30 discharges a day. It has three working modes (sensor, timed and continuous) and a 150° radar sensor that works within 2.5 metres. Read Wireless Water Fountains: Are They Better? for the trade-offs.
5. Filters
Every fountain here uses a filter that you replace every 2 to 4 weeks, and the 2L, 3.2L and wireless pump models ask you to soak a new filter before fitting it. Spare filters are sold separately, for example the 2L fountain replacement filter and the wireless pump fountain replacement filter. Browse every spare in our accessories collection.
6. More than one cat
The 3.2L wireless fountain is listed as suitable for multiple cats and medium to large dogs, and the wireless pump fountain has a dual bowl design. Our guides Best Water Fountain for Multi-Cat Homes and How Many Water Fountains Does a Multi-Cat Home Need? help you plan.
7. Want food and water in one?
The 2-in-1 feeder and fountain pairs a 5L food tank with a 3.5L gravity-fed water fountain. Read 2-in-1 Feeder and Fountain: A Buyer's Guide to see whether it suits you.
Keeping it clean
Wash the fountain regularly with warm water and mild soap and change the filter on schedule. See How to Clean a Pet Fountain Step by Step and Signs Your Cat's Water Fountain Needs Cleaning. Browse every model in the pet water fountain collection.
