I just thought of "Blue Moon" laundry detergent, which probably inspired me to think of the concept of "second floor space" with a slightly different name. After all, clothes are also divided into two layers, and stains are also divided into two layers. This name should be more "professional" in expectation. Although we don't think of "laundry detergent" directly when we only face this name, it is easy for customers to think of its "special effects" as a kind of product sales combined with physical objects.
In addition, the name also has the desire to "roam"! That is, "swimming" in this "new feeling and new atmosphere". Recommended!
