Xiaomi Zanjia Water Saver Nozzle Tap – Automatic Sensor Faucet with USB Rechargeable Battery

The Xiaomi Zanjia Water Saver Nozzle Tap is a smart touchless faucet adapter designed to convert a compatible regular faucet into an automatic sensor-controlled water outlet.

Instead of touching the faucet handle every time you need water, the Zanjia adapter uses infrared sensors to detect hand movement and automatically control water flow. Its dual-sensor design provides different sensing areas for convenient everyday use.

The device also uses water-saving and air-injection technology to create a comfortable water stream while helping reduce unnecessary water consumption. Current product specifications list a 550mAh rechargeable battery, USB charging, approximately 3 hours charging time and up to 6 months of battery endurance under stated conditions.

The Zanjia is commonly sold as a Xiaomi ecosystem product, although some versions may carry Zanjia or Xiaoda branding rather than a Xiaomi logo. Buyers should verify the exact branding and version supplied by the seller.

Common Problems with Traditional Faucets

Traditional manual faucets can create several everyday inconveniences:

• Touching the faucet repeatedly with dirty hands
• Leaving water running unnecessarily
• Difficulty controlling water flow while washing
• Wasting water during hand washing
• Reaching for the faucet handle with wet hands
• Water splashing from a strong direct stream
• Needing to replace the entire faucet for touchless operation

The Zanjia Water Saver Nozzle Tap provides a simple way to add automatic water control to a compatible existing faucet.

Smart Solution: Touchless Water Control

The Zanjia combines infrared sensing, automatic water control and water-saving aeration in one compact faucet attachment.

How It Works

Hand Detected → Sensor Activates → Water Flows → Hand Removed → Water Stops

The device uses two sensing areas. The lower sensor is designed for short-duration hands-under-the-tap operation, while the side sensor can be used for longer continuous water flow depending on the operating mode.

This makes everyday tasks such as washing hands, rinsing food and cleaning dishes more convenient without repeatedly touching the faucet.

Key Features

1. Automatic Infrared Sensor

The built-in infrared sensors detect hand movement without requiring physical contact with the faucet.

Current specifications list a side sensing range of approximately 0–5cm and a bottom sensing range of approximately 0–10cm.

2. Dual-Sensor Design

The Zanjia uses two sensing areas for different water-control situations.

The bottom sensor is suitable for quick hand-washing or short water-flow actions, while the side sensor can provide an alternative control method for longer water flow.

3. Water-Saving Air Injection Technology

The nozzle combines water with air to create a comfortable and effective stream while reducing unnecessary water usage.

Some Zanjia product listings claim water savings of up to 65% compared with a conventional faucet, but actual savings depend on the faucet, water pressure, usage pattern and operating conditions.

4. USB Rechargeable Battery

The device includes a built-in rechargeable battery rather than requiring regular disposable batteries.

The commonly listed configuration uses a 550mAh battery, with approximately 3 hours charging time and up to 6 months of endurance under specified usage conditions.

5. Convenient USB Charging

The faucet adapter can be recharged using USB.

The charging connection is located on the device body and is protected by a cover on versions designed to help keep moisture away from the charging port.

6. Fast Sensor Response

Some Zanjia product descriptions specify approximately 0.25-second induction response, allowing water to start quickly after the sensor detects a hand.

7. Automatic Water Shut-Off

The touchless system is designed to stop water flow when the user removes their hand from the sensing area in the automatic mode.

This can help reduce water wastage caused by leaving a manual faucet running.

8. IPX6 Protection

Current product specifications list an IPX6 protection rating for the device.

This indicates strong resistance to water jets under the applicable testing conditions. It should not, however, be treated as permission to submerge the entire device.

9. Overflow Protection

The Zanjia is listed with overflow protection, providing an additional safety feature for automatic water control.

10. Multiple Water Flow Modes

Some Zanjia listings describe two water-flow modes, allowing users to choose between different stream patterns for tasks such as hand washing and cleaning.

Exact operating modes can vary by version.

11. Easy Installation

The Zanjia is designed as a faucet attachment rather than a complete plumbing replacement.

Depending on the supplied adapter set, it can be installed on compatible faucets using the included connectors and sealing components. Some product descriptions list six connector types for compatibility with commonly used faucet configurations.

12. Compact & Lightweight Design

The commonly listed dimensions are approximately 60 × 34 × 49mm, with a listed weight of approximately 105g.

Its compact construction keeps the automatic sensor mechanism relatively unobtrusive around the sink.
