I'm having issues where my RV30 Plus will not always hoover right up under the kitchen cupboards and right up to the kickboards. They're all the same height, there's sufficient height for the robot to get underneath, but oddly the robot will only go right underneath some of them. To the extent, that it will hoover along a few metres under the cupboards, then decide it needs to move out from underneath for the rest of the length of the cupboards and leave a ~10 cm gap of unhoovered crumbs.

Any ideas or tips on how to get the RV30 to hoover right underneath all kickboards?
