First time I sent down, they say same thing as you. Then wife said they change wifi module. After that briefly connected and then spoil again. My wife is banker not engineer. But if my washing machine, smart light, lock, fan, tv, dishwasher all can connect, cannot be my wifi issue right? Elvin Tay also not engineer trained but i think simple logic I also can understand.
I see a few new models broke down lei. Like T30 omni, another one flagship x series I think. My ex roborock 4 years retire in glory. Backside itchy, now I do housework myself.
