First of all, the suction technology was first pioneered by Hansgrohe. The suction position is at the head of the shower head. Someone has analyzed the principle of it before. Here I will focus on several previous technologies. Effect difference.
Undoubtedly, Hansgrohe's suction effect should be recognized as the best. As the first manufacturer to develop such technology, it occupies the most advantageous position of the suction port. The inhalation effect is full, and since the water contains air, it can save water without weakening the strength when hitting the body. As for what the promotion says about beauty, there is no practical value.
As for Moen’s suction technology, it simply uses a suction hole at the plug. Since water in this position is prone to backflow, it will cause the illusion of water leakage, so this product often has customer complaints. This is not Moen’s patented technology. As a leading brand in the United States, its shower design capabilities are constantly weakening. Without innovation, it can only use the existing technology of Chinese manufacturers for development. The inhalation technology here is Xiamen Songlin’s technology. Songlin has a strong reputation in shower technology in the industry and has strong proposal capabilities. From my observation, this suction technology is average, and the air content and water-saving effect are naturally inferior to Hansgrohe.
