☀【Energy Saving and Environmental Protection】: Our fountain is completely powered by sunlight, no battery or external power supply is needed, just enough sunlight to start working (100% environmental protection). ☀【6 Types of Nozzles】: 6 different nozzles can meet your different needs for fountain height or shape. Different water spray effects can be achieved by combining or changing spray heads to create the perfect fountain. ☀【Easy to Install and Use】: Simply replace the preferred spray head. When using the solar fountain, place the pump in the water to expel air from the pump. When there is enough sunlight, the pump will automatically start within 3 seconds. The stronger the sun, the more water can be pumped. ☀【Multiple Uses】: Our fountains are widely used, suitable for bird baths, pools, rockery decoration, pond water oxygenation, etc. You can also use our products to provide water for your dog and add more fun to your dog's water. ☀【Recommendation】: Make sure there is enough water to keep the pump fully submerged. Place the product under unobstructed sunlight when in use. Shade or obstructions will affect the normal operation of the pump. When the sun is weak, the pump will not work continuously, but will start automatically repeatedly until the sun reaches a certain strength to restore continuous operation of the pump. You should clean the pump regularly to prevent debris from clogging the pump.
