Roidmi Eve Plus Robot Vacuum Not Connecting to Wi-Fi

I purchased the Roidmi Eve Plus robot vacuum, but I haven't been able to connect it to Wi-Fi since day one. There is no video guide or customer support line available to help resolve this issue. The authorized service directs me to a support service, which never answers. I even searched YouTube for tutorials, but there’s nothing there either. The user manual doesn’t provide any useful solutions, and I’m left with a vacuum that I haven't been able to use even once. The device just won't recognize Wi-Fi, and there seems to be no solution in sight. It’s incredibly frustrating to spend money on a product that comes with zero effective customer support or troubleshooting options.
