It presents a powerful mode for deep cleaning and a gum massage mode, alongside a whitening option that requires a gel for optimal results. The RONGCHUANG toothbrush similarly features four cleaning modes, including powerful and gum care options, allowing users to customize their brushing experience. Both products promise to deliver three times the cleanliness compared to manual brushes, showcasing their advanced cleaning technology.
Battery and Charging
