Maybe my point of view is a bit old-fashioned. I don't think it is necessary to buy a smart toilet. First of all, the toilet is a tool for going to the toilet. The hand-flushed toilet is very mature. Nowadays, the smart toilet only adds some electrical equipment, but its price is relatively expensive. In addition, although it is convenient to use, it is hard to throw away when it is not used, so I don't think it is necessary to buy a smart toilet.
