Multiple uses: Place this water fountain in your birdbath, pool, pond or other water source to create a beautiful water decoration. Solar powered: The fountain is powered by solar cells and therefore does not require batteries or electricity. The fountain only needs a few seconds of direct sunlight to start working. It sprays about 10 - 20 cm into the air depending on how strong the sunlight is on it. 4 different nozzles: You can choose from four different interchangeable nozzles to get different effects on the water that is sprayed. Keep in mind that the fountain pump must be covered with water for it to work. Note: 1. This product is a solar-powered water pump without an external battery. The height of the water jet depends entirely on the strength of the sun. When the sun is weak, the pump will not work continuously but will automatically start over and over again until it has enough energy to return to its continuous working mode. Place the product in direct and free sunlight. In the shade, the pump does not receive enough energy for normal operation. 2. The pump must be completely submerged in the water and the water pump should be cleaned regularly. 3. Handle the water fountain with care as the solar panel is very sensitive. 4. Contact customer service if you notice any cracks or damage to the solar panel.
