Hi, everyone

I bought the Rv20 Mop about three weeks ago. Since then it has been cleaning every day without any problems using the same pattern and the same map. Since yesterday, it has been spinning and moving the wrong way as if there were objects in the way.

I cleaned all the sensors (which were clean)
The battery was 100% charged
The tank was empty
No changes to the map or new objects

The cleaning time has doubled and there are places it passes several times and others it doesn't pass at all. It seems that there is a problem with the algorithm that causes this problem after a certain number of cleanings. It's desperate to see and hear the robot circling in an empty room when a few days ago it was cleaning at full speed. I can't imagine what the floor will look like if I put the mop down.

Model RV20 Mop
Hardware version 1.0
Firmware version 1.1.3 build 240103 Rel. 150809

Is there an update planned to correct this problem?

Have you identified the root cause?

At the moment the robot is slow and not very useful, what was a positive experience is quickly becoming a bad one.
