During Amazon's Prime Day (July 8-11, 2025), emerging smart bathroom brand XCQQ achieved explosive growth with its flagship S9B Series instant-heating bidet toilet seat. Data shows that the series' first-day sales exceeded 2,000 units, a year-on-year increase of 180%, quickly climbing to the 6th position in Amazon US's Bidet Seats category and emerging as one of the most promising dark horse brands in this year's sales event.

The XCQQ S9B Series stands out with its core technological breakthroughs: "instant heating on demand, zero water tank design," perfectly aligning with the dual demands of energy efficiency and health in the North American market. Unlike traditional heat-storage products that continuously heat water in tanks (a high-energy-consuming model), the S9B Series adopts dynamic variable-frequency instant heating technology, which only heats water when in use, saving over 35% in electricity. This technological advantage attracted a large number of eco-conscious household users during Prime Day, with product page views surging 420% compared to usual, and the add-to-cart rate reaching 2.3 times the industry average.
