The ROJECO 3.2L Wireless Stainless Steel Fountain is a cord-free pet water fountain with a radar sensor, three working modes and a rechargeable 4000mAh battery. Its 304 stainless steel body holds 3.2L of water, a four-layer filter keeps the water clean, and the pump runs at less than 20dB. It can run on battery or plugged in, so you can place it wherever your cat likes to drink, indoors or outdoors.

Six features at a glance
The manufacturer's feature cards are Radar Sensor with 24-hour fresh water flow, Wireless Water Pump with free positioning, Multiple Filtration System, 304 Stainless Steel, Ultra Quiet Working at less than 20dB, and 3.2L Large Capacity. Each one is covered below.

Radar sensor: fresh water when your cat arrives
The 150° radar sensor captures your cat's movement within 2.5 metres. In Sensor Mode the sensor light comes on and water is dispensed when the cat approaches, so the water is not running all day and the battery lasts longer.

Timed and continuous modes
Timed Mode releases water for 15 seconds every 15 minutes, which suits pets that prefer to find fresh water at regular intervals. Continuous Mode is for pets who like a steady stream: plug the fountain in and the water keeps coming out. The picture shows the fountain plugged into a wall socket for continuous running.

Wireless or plugged in
The fountain supports dual power, so you can use it on battery or plugged in. The manufacturer notes it can be placed flexibly indoors and outdoors, and running it on battery means there is no cord lying around for pets to chew. The photo shows a cat walking up to the fountain, with its faucet, the blue water-level window and the black host module.


Four-layer filtration
The filter is built from four layers that intercept impurities and remove odours so the water stays fresh:
-
Activated carbon: purification and deodorisation.
-
Ion exchange resin: softens the water and removes heavy metals.
-
Non-woven fabric: intercepts hair and debris.
-
High-density pump sponge: adsorbs small particles.
The manufacturer recommends replacing the filter every 2 to 4 weeks, and soaking and washing a new filter before you install it.


4000mAh battery and 50-day standby
A 4000mAh lithium-ion battery lets you use the fountain wirelessly, and the manufacturer lists up to 50 days of standby from a full charge. That figure is measured at 30 water discharges per day, so heavier use will shorten it.


3.2L capacity for multi-cat homes
The 3.2L tank can support 1 to 3 cats drinking from it. The capacity cards describe it as suitable for multi-pet families and for short trips, with a full tank lasting a pet 9 to 14 days of drinking. The cutaway shows the round water-level window, the filter and the pump inside.


304 food-grade stainless steel
The tray and water container are 304 food-grade stainless steel, which the manufacturer describes as rust-free and corrosion resistant, and states complies with the Chinese national GB4806 safety standards. The comparison picture sets the ROJECO Stainless Steel Pet Fountain against a plastic pet water fountain.


Ultra-quiet pump
The upgraded mute pump runs at less than 20dB. The manufacturer's chart places the drinking fountain below a murmuring human voice at 30dB and close to the sound of falling leaves at 15dB, so it sits quietly in a bedroom, living room or study.

Easy to clean
The simple structure comes apart quickly. The manufacturer shows the water container and tray being washed by hand under a tap or in a dishwasher. The host body is not waterproof and cannot be washed, so wipe it with a damp cloth and keep it out of the water. Our guide to how to clean a pet fountain step by step has a full routine.

-
Visualisation window: makes it easy to see how much water is left.
-

Frequently asked questions
How does the sensor mode work?
A 150° radar sensor detects your cat's movement within 2.5 metres. When the cat comes close the sensor light comes on and the fountain dispenses water.
What are the three modes?
Sensor mode dispenses water when a cat approaches. Timed mode runs the water for 15 seconds every 15 minutes. Continuous mode keeps the water coming out while the fountain is plugged in.
How long does the battery last?
The manufacturer lists up to 50 days of standby from a full charge of the 4000mAh battery, measured at 30 water discharges per day. Heavier use will shorten this, and some listings of this model quote about 35 days, so treat 50 days as the best case.
Can I use it plugged in?
Yes. It supports battery and plug-in dual power, and continuous mode needs the fountain to be plugged in.
How many pets can drink from it?
The manufacturer says the 3.2L tank supports 1 to 3 cats drinking at once, and the parameter card lists multiple cats and medium to large dogs.
How often should I change the filter?
The manufacturer recommends every 2 to 4 weeks. Soak and wash a new filter before you install it.
Can I put it in the dishwasher?
The water container and tray can be washed by hand or in a dishwasher. The host body is not waterproof and cannot be washed, so wipe it clean instead.
How loud is it?
The silent pump runs at less than 20dB, quieter than a murmuring voice at 30dB on the manufacturer's chart.
