Small dust leakage into dustbin area X50 Ultra

Hello,

I observed that sometimes fine dust leakage(not a big leakage) from main dustbin into dustbin area in robot X50 Ultra, around connection between dustbin and robot dustbin area through gasket. I was using before a model of roborock, it has also the same issue. I would like to know if you also experinced it, is it normal or not? If there is a air leakage on gasket, it can also affact badly the vacuum performance, so just I want to be sure about it.

Thanks in advance.

Just to be more clear, I added the screenshot to show where was the exact fine dust in dustbin area. I marked it with green color, dust was at that area. In this screenshot you cannot see the dust, because I already cleaned it

Hello, I also checked again after many runs, it is in reasonable manner, actually I dont see it again, just very small dust sometimes, but generally the dustbin area is clean.
