Instructions for Use 1. Open the water tank cover and add warm water (Adding cold water into the brush may not come with water mist in winter in very cold areas. The brush has no heating function. If the spray port is close to the pet's skin, the water mist that comes out will not be cool. If it is farther away, the water mist will be cool, because the weather is cold in winter) 2. Press the switch and make the steam outlet face the ground (If the steam outlet faces upward to the sky, the brush will stop producing steam. If that, please point the spray nozzle downward and shake the brush a few times, it will work normally) 3. After working for 5 minutes each time, the brush will automatically stop working. You need to press the switch again (This is to prevent forgetting to turn it off after grooming) 4. Comes with a charging cable. The battery can be recharged after it is exhausted. Please use a charger with a power of no more than 5V 1A. Exceeding the rated power will cause damage. When charging, the indicator light is red. The indicator light turns off when fully charged. (It takes 30 minutes to fully charge and can work for 30 minutes after that)
