Problem addressed

Since bacteria and viruses are more easier to breed and spread in the toilet, cleaning staff who staying and working in the toilet for a long time will increase the risk of infection.

  • With the adoption of the cutting-edge Simultaneous Localisation and Mapping (SLAM) and Automated Guided Vehicle (AGV) driving technology, the toilet-bowl cleaning robot can automatically and autonomously shuttle around the toilet environment and perform its cleaning duties.
  • Using AI-based vision technology, the robot analyses the cleanliness of the toilet while cleaning, provides suitable cleaning strategies, and timely reports the cleaning situation to the administrator.
Key impact
  • With only minimal renovations to the existing toilet, a toilet attendant or administrator can use the toilet cleaning robot to perform scheduled and on-demand toilet bowl cleaning work
  • Reduce the risk of viral transmission
  • Raise the public awareness of public hyigene
