Staaaaaaay away!!
Staaaaaaay away. They sell machines that do not connect to the internet. The support guy told me to RETURN it because THE DEVICE CONNECT ONLY TO SPECIFIC NETWORK TYPES AND NOT ALL NETWORKS (including condo/university/residence networks). So, their SMART solution was to use hotspot from ANOTHER PHONE to use the machine. What if I do not have another phone? Maybe get married so that you can use their machines. A wife for a hotspot so that roborock can sell their non engineered machines. I pray they go bankrupt soon.
