Hi, This is my 4th Roborock vacuum. I have 3 S5's and now this new S4. The problem is straight out of the box the S4 will not operate on carpet with the side brush installed. It does circles and errors out. I removed the side brush and now all is well. Obviously this causes an issue for areas where there is no carpet on the floor it is vacuuming. Is this a typical thing with the S4? I have an email into support for this as well.
