I was very happy with its performance for many months but my S4 is no longer working right. As soon as it leaves the dock for cleaning it exhibits very strange behavior, running into the dock multiple times before finally giving me an Error 8. I've linked to a video showing the S4 shortly after starting cleaning. Any thoughts?
Two thoughts. When was the last time you cleaned the sensors? While probably less of a concern, the manual calls for more free space to the left of the dock.
I just tried both of your recommendations and got the same erratic behavior. But thank you for the suggestions!
Hello,
Thanks for reaching out.
Turn over the robot and ensure that there is nothing stuck in the wheels.
From the video attached, I found that the dock locates on the carpet. Try to move the dock to hard floor and The space for the dock should be no less than 0.5 m wide on the left and right side, and 1.5 m wide in front of it.
Besides, did it work well on the carpet before? Please tell us the purchase info, including seller's name, purchase date and order number.
Note: You can email us these info via support@roborock.com
Another customer support member communicated with me by email. A popped balloon had been lodged in the right wheel and, once removed, the S4 resumed operating normally. Thanks!
Gotcha, thanks for your updates. It is glad to hear that you figured it out.
If you have any further question, be free to let us know.
Update: I have reset the S4 multiple times, but that hasn't fixed the issue.
Another update: I tried using the remote control function today. When I pressed forward, the S4 moved backward. Any thoughts?
