Roborock S5 navigation issue after 3.5.8_002034 firmware updatem_____02/01/2021 13:23 1919 3 0

Hi,

I have used my Roborock one year now. There has been few FW updates already and I have not faced any issues with them. Now with latest update to version 3.5.8_002034 I have faced issue with navigation. Roborock seem to randomily vacuum only some areas of house or of certain room. I tried to reset the map by disabling and enabling "Map saved mode (Beta)" from Vacuum settings in app, but it did not have any impact. Here's couple screenshots from app when full house is tried to vacuum, but without success.

What should I do to get my Roborock work as it was before FW update?

Hi,

 

Thanks for your feedback.

I. May I suggest you move the dock to the central area of your house to have a try?

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.

II. Then pls reset the map and create a new one.

III. Please use a piece of cloth the clean the wall sensor at right of device

like attached picture to have a try. If problem still exists, could you please send us a picture of wall sensor? You need to open the flash when taking photo of wall sensor so that it could show inside of sensor clearly.

I reply to my self, issue is solved. This is just FYI for others who may have same problems.

Key word is "wet cloth"! I already clean all the sensors yesterday with dry cloth and sensors were clean, however today I noticed that after yesterday trials they were totally covered by dust. Now I used wet cloth and sensors stayed clean. Might be that sensors plastics were electrostatic charged due to very dry relative humidity (<25%) in my house and it gather all dust to it, but after wet close it might discharge electrostatic charge from plastic..

Anyway impact was huge and I did nothing else for Roborock than just clean sensors with wet cloth.
