AUTOMATIC SENSOR PET WATER FOUNTAIN · 3 L
YS-4 Automatic Sensor Pet Water Fountain — 3 L Hands-Free Fountain with 120° Auto Flow and Two Water Modes

- Hands-free auto sensor — a 120° sensor starts the flow as your pet approaches, so there is nothing to press and no water wasted while nobody drinks.
- Two flow modes — run it with the gooseneck faucet fitted, or without it as a low fountain stream.
- 3 L food-grade PC tank — transparent, odour-free and strong; you can see the level without opening the lid.
- 20 dB quiet, 5 V safe — sleep-level noise, and 5 V USB input that runs from an adapter or a power bank.
- Filter cotton + activated carbon — a two-stage filter catches hair and takes the smell out of the water.
Hands-Free: Water Starts When Your Pet Arrives
A 120° infrared sensor covers the approach. Your cat walks up, the pump starts; it walks away, the pump stops. No button, no wasted circulation, and a bowl that is always wet when a pet checks it.
Two Flow Modes, One Body
Fit the gooseneck spout for a raised tap-style stream, or leave it off for a shallow fountain. The same unit covers cats that prefer either — useful when you do not know the end customer's cat.
3 L Tank, One Fill a Week
3 L is about five 600 ml bottles of water — roughly a week for one cat. The tank is clear, so the level is visible at a glance, and the tray lifts out for washing.
20 dB — Sleep-Level Quiet
At 20 dB the pump is quieter than a fridge and quieter than a washing machine. It can sit in a bedroom without a hum.
5 V USB — No Leakage Risk
5 V input means an adapter, a laptop or a power bank will all run it, and the low voltage removes any mains-leakage worry near a water bowl. A battery level display sits on the front panel.
Food-Grade PC, Strips Down to Wash
The tank is food-grade polycarbonate — odour-free, high-strength and clear. Tray, tank, filter slot and pump all separate for cleaning, with no sealed corners.

Frequently Asked Questions
Does the fountain run all the time?
Only when the sensor sees a pet. The 120° infrared sensor starts the pump on approach and stops it when the pet leaves, which is why 3 L lasts so long.
Can I use it without the faucet?
Yes. Leave the gooseneck spout off and the water comes out as a low fountain stream instead.
What does it need to run?
5 V USB. Any phone adapter or power bank works; the front panel shows the charge level.
Is the plastic safe for drinking water?
The tank is food-grade PC — odour-free and made for drinking water. The drinking tray itself is 304 stainless steel.
Do you offer OEM / private label?
Yes. Custom logo, packaging and manual from 300 units per model — request a quote with your target market.

Where the YS-4 fits in the range
The YS-4 is the sensor model in a plastic body: 3 L, food-grade PC tank, 120° auto flow and two water modes, at a lower unit cost than the stainless YS-3.
For a wholesale range it is the volume SKU of the sensor pair — same hands-free story, plastic tank, 18 per carton instead of 20, which trims freight per unit on mixed containers.
