Robot LeoScrubs is in charge of mopping and drying the floor from the splash of the Rain Vortex indoor waterfall at Jewel Changi Airport. Every time there is a puddle on the floor, the robot immediately mops it so that visitors don't slip on the dry floor. Previously, this work was done every 10 minutes by an unknown janitor.

Visitors can also scan the QR code on this robot to display a menu with a list of questions to interact with the robot and even ask the robot to sing.

Jewel is also piloting a robot guiding directions to shops within the mall and also selling tickets for tourist attractions. This robot is planned to be launched at the end of the year.

There is also a robot LeoPull, which is in charge of collecting waste from shops at Changi Airport to be taken to landfills. LeoPull pulled a large trash can and would stop in front of each store and ring the bell to notify tenants of his arrival.

A series of sensors also help the robot avoid obstacles and people, and tell the operator what to do at a given point. Operators can also provide instructions, if needed, through the app.

Among the various robots, the most popular is the Delight robot which distributes drinking water and candy to Jewel visitors in the Canopy Park area.

There are currently more than 40 robots performing various types of work at Changi Airport. According to airport management, the use of robots has helped ease the tedious and tedious task previously carried out by staff.
