Automatic pet feeder Xiaomi Smart Pet Fountain 2 3 L waterer carbon filter plastic white battery/DC 5 V 2 A 230×180×190 mm

The Xiaomi Smart Pet Fountain 2 is a 3 L automatic waterer for cats and small dogs that supports both a 4000 mAh rechargeable battery and DC input (5 V, 2 A). Designed for continuous healthy hydration, the fountain combines a compact white plastic body (230×180×190 mm) with four-stage filtration and three selectable water-output modes. The unit is IPX7 water-resistant, easy to disassemble for cleaning, and can be monitored and controlled via the Xiaomi Home app.

Advantages

The rechargeable 4000 mAh battery provides up to 100 days of operation on a single charge, allowing placement anywhere without needing a permanent power socket and reducing the risk of chewed cables. A four-stage filter (high-density microporous PP, activated carbon granules, mixed ion-exchange resin, and bacteriostatic cotton) removes impurities, absorbs odours, reduces hardness ions and inhibits bacteria to keep water fresh and safe. The fountain offers quiet operation suitable for bedrooms, IPX7 protection for easy rinsing, a transparent water window for level monitoring, boil-dry protection to stop the pump at low water levels, and anti-slip feet for stability.

Suitable for

• Cats and small dogs
• Households with one or several pets
• Owners who need a wireless solution for temporary absences
• Homes where quiet operation and easy cleaning are required

How to use

Fill the 3 L reservoir with fresh water, install the four-stage filter according to the included instructions, and choose the desired water-output mode: Sensor mode (dispenses 10 seconds when the pet approaches), Intermittent mode (scheduled intervals), or Continuous mode (constant flow). For wireless placement, charge the 4000 mAh battery fully before first use or connect the fountain to a 5 V, 2 A DC adapter. Use the Xiaomi Home app to monitor water level, receive filter and battery alerts, and adjust settings remotely.

Usage recommendations

Replace the filter according to the manufacturer’s schedule and clean the fountain weekly. Keep the water reservoir topped up to avoid activating boil-dry protection and ensure the pump’s longevity. If used in multi-pet households, check water level more frequently and select a suitable output mode to maintain fresh water for all pets.
