Area along the underside of my counters - brush extension?

I have ran my back three times in this area of my kitchen and it refuses to get anything that's under this small overhang. I tried to identify it as a small overhang but something's going on with the app and it won't be saved after I identify it. Regardless, I'm shocked that it's not picking these items up because there's only about 3 in of space from the kick plate to the edge of the counter. Any suggestions on how to provoke my back into actually extending the brush arm to try to get the rest of this debris?

While it seems silly, try adding a curtain on the map where your toe kicks are. The robot will travel further under your toe kicks and hopefully the arm will reach better!
