L10 Prime is making strange noise.

My L10 prime started to make strange noise today when I started it for cleaning. I checked the bush and mop pads but the sound persists.

Hi, this noise is caused by dust/debris entering the vacuum pump of the robot. This may happen due to overuse of the filter even after it is worn out, causing the dust to pass through filter and enter the vacuum pump.

You may want to replace the filter and raise service ticket for cleaning of vacuum pump
