Robot Vacuum Cleaner Mobile

Japan's Fuji Heavy Industries Ltd. has launched a high-floor, dust-proof robot that looks like a portable washing machine.

Researchers hope that such robots will help solve the pressing problem facing the rising sun: how to cope with aging population and declining labor force. .

The RFS1 vacuum cleaner will be equipped with 10 high rise buildings in Japan, including a 54 storey building in central Tokyo. The robot will operate overnight after the office workers have gone home. It will go up each floor by elevator to clean the corridor.
