I'm interested in exploring your range of toilet models that come equipped with automatic open/close lids as well as automatic flushing features. Could you provide details on the various options available, along with their pricing? Additionally, I'd like to know whether these models require a power outlet installed within the toilet unit itself for operation. Also, can you clarify the installation process for these toilets? Is it straightforward, or are there specific requirements or complexities involved? Any information you provide will be helpful as I consider my options. Looking forward to your detailed response!
