Hello,
I have had the Roborock S4 for about two months and I use the roborock app. It was working fine but lately it keeps saying off-line. When I clicked under the robot it just shows loading a map and won’t load anything so I can’t even click on the icon to update firmware. The other day I played with it by using the plus button to add a new Robo rock and after about five times I finally got it to get online and then I exited back out and went into my robo rock map and it vacuumed. I was hoping that fixed it but today it’s off-line again and when I try to add a new roborock, it’ll connect to the Wi-Fi and connect the roborock to WiFi, but won’t do the third step and just fails. I tried multiple times and can’t get it to get online. What do I do?
We are sorry for the trouble you are facing and for all the inconvenience.
1. Could you please try to delete the S4 in app by long tapping the card as attached picture? And then to reset WiFi for S4.
2. If by any chance, you are able to reconnect it, may we suggest you try to check if there is any firmware update available as attached picture.
