Hi,
I have an S7 and it works great, however when the front half of the robot is on hardwood floor and the back half is on carpet, the robot thinks it's completely on hardwood floor so it lowers the mop. When that happens the robot gets stuck on the carpet and errors out because of the wet mop sticking to the carpet. It would be beneficial to incorporate a secondary carpet sensor at the back of the robot to prevent this from happening.
Good point. We would note it down. Thanks for the feedback.
