dustbin blockage with R7070

I have the R7070 POWERbot and am overall very happy with it other than a couple of issues.

One of them is the blockage of the dustbin flow.

While the dust gets sucked in at the bottom side hole and twirls up the top, it doesn't always seem to make it over the lip and into the dustbin itself.

What I end up with is a bunch of dust collected at the top like this, and not a lot of dust ending up in the bin like this.

 

It appears to me that the lip at the top of the dustbin needs to be a bit deeper which would allow for more to flow through. I'm tempted to modify it myself.

 

Has anyone else had this issue, and if so - what have you done about it?
