Is the mop cloth clean? Try to replace a dry and clean mop cloth.

Hello,

 

I have tested this now. When I use a dry mop, the first run goes quite well.

 

However, during the second run, the robot vacuum loses its orientation.

 

If I stop and restart, it turns into complete chaos.

 

I usually select the maximum moisture setting and have it go over the area three times.

 

It also seems to be related to the fact that problems arise when the mop is wet.

 

Although, it should be obvious that the mop is wet in mopping mode.

 

This issue has been occurring for the past 2–3 weeks. Before that, everything worked fine.

 

I suspect a software problem.

 

Can you help with this?

 

Best regards,

Nils Bödeker

To me, this is more look like a hardware issue, something to do with the wheels. I would recommend getting a replacement first, you may proceed with the warranty with the retailer or the local TP-Link support.

  @Wayne-TP I took an having this exact same issue where the mop is installed and it is making irrational movements and not following a grid pattern.

 

This was all happening with a clean mop and basically started to do this a few minutes in acting like it was stuck but it was on flat level ground. It would also start doing patterns as if there was a table leg in the way trying to circle the table leg but there was no object in the way.

Which model do you have? Check whether the sensor area is dirty, clean it before sending it out.
