Claims26
A cleaning system for a passenger conveyor system, the passenger conveyor system comprising one or more conveying devices, the conveying device being an escalator or a moving walkway, the cleaning system comprising:
- a self-mobility cleaning device configured to move, in response to a cleaning request, to an entrance or exit of the conveying device designated by the cleaning request and to perform a cleaning operation on the designated conveying device.
A cleaning device for a passenger conveyor system, the passenger conveyor system comprising one or more conveying devices, the conveying device being an escalator or a moving walkway, the cleaning device comprising:
- a wireless communication unit;
- a moving mechanism;
- a cleaning mechanism;
- a processor coupled with the wireless communication unit, configured to:
