The first generation of the Internet of Things(IoT)-enabled Smart Toilet Bowl Cleaning System developed by the EMSD was awarded the Gold Medal at the International Exhibition of Inventions of Geneva 2021. The team has continued to make advancement by utilising innovative technologies, and eventually upgraded the system to its second generation, which was given a trial run at the EMSD Headquarters. We will invite client departments to come and experience the system’s performance, as well as exploring its wider application in toilets in different venues upon completion of its commissioning in June.
Both the performance and functionality of the second generation of the IoT-enabled Smart Toilet Bowl Cleaning System have been improved, making it more convenient for application and management in different venues. Compared to the first generation of the system, the new design adds in a full auto mode, providing autonomous cleaning function. The new generation of the system consists of a toilet bowl cleaning robot, an automated guided vehicle, and an IoT-based sanitation monitoring platform. The system can collect data on the usage and odour level of individual toilet cubicles in real time and provide real-time data analysis to monitor the cleanliness of toilets. The second generation of the toilet bowl cleaning robot also features a brand new design that includes an auto-navigation chassis and an enhanced cleaning function, which improves cleaning results. In addition to scheduled cleaning, the robot can increase the frequency of cleaning by navigating itself to individual toilet cubicles according to the actual needs deduced from IoT data monitoring. The robot employs artificial intelligence to carry out real-time image analysis of the inner wall of toilet bowls, and assesses their cleanliness which are categorised into three levels, namely “clean”, “normal” and “dirty”. Upon the assessment, the robot uses specific cleaning modes with varying amount of water and scrubbing procedures to clean the inner walls and rims of the toilet bowls. Following the cleaning process, the robot will evaluate the cleaning results and initiate another cleaning cycle if stains are still found.
Smart toilets are an essential and indispensable facility of a smart city. The new IoT-enabled Smart Toilet Bowl Cleaning System not only enhances hygiene of toilets and lowers the risk of the spread of germs and viruses, but also improves the working environment of cleaning staff and reduces their workload, achieving a comprehensive enhancement of management effectiveness of toilets with innovative technologies.
