Vac makes a squeaky noise when traveling in a straight line (travelling faster). I have done the main brush replacement and cleaned the side brush and the small wheel and every thing else accessible...

@Wayne-TP Ok thank you.

@Wayne-TP Thanks Wayne. I will try that. Yes I did expect the vac would avoid the furniture area. So now I wonder why mark furniture and mats otherwise?

Hi my robo vac does not recognize furniture and a mat which is on the map. Any ideas please
