The hygiene management of the
full body sex doll faces new challenges due to weight gain. The modular design of the
fat sex doll allows for partitioned disassembly and washing, and the weight of each independent component is controlled within 8kg. The application of nano self-cleaning coating reduces the surface stain adhesion rate by 73%. With the rotatable base design, a single person can complete the full-scale cleaning of 90kg-level products.
