Do you see the evolution of iRobot-esque autonomous cleaners as a threat to your business? Are you planning on pulling an uber with all the capital you raise and pursuing R&D of said devices?
Cleaning is very sophisticated and complicated work. We observed even small detail can change customers' satisfaction. Current robot technology is still very early to handle complex human work like cleaning.
In a longterm, robotic tech is opportunity rather than threats. Though we do not have specific plan to make autonomous cleaning system, we can take advantage from robot innovation.
