Effectively reduces bacteria. The module has built-in small beads that filter clean water to reduce bacteria more effectively, providing peace of mind during use. Function: Utilizes electrolytic silver technology, allowing the water in the clean water tank to contain a certain concentration of silver ions. These ions help sterilize the floor during mopping, achieving a sterilization rate of up to 99.9%. The clean water tank is specially designed for easy installation. Remove the filter accessories at the bottom of the clean water tank and install the silver ion module by pressing it tightly. This dual-function system ensures fresher floors, making barefoot play safe and worry-free. Silver ions travel through the waterway to deliver effective cleaning performance. Children can run barefoot indoors while mothers stay confident about cleanliness. When inserting the silver ion module into the middle of the water pipe for the first time, the front of the pipe may feel tight. Apply slight pressure to ensure proper insertion. Reinsert the water pipe into the water outlet of the clean water tank with firm pressure to ensure a secure fit.
