As the header mentions, sometimes the brush extend works under my cabinets and other times it does not. See video where half the cabinets gets the treatment but the other half does not. A lot of dirt gets missed this way.
The special structure of the groove at the bottom of the cabinet is indeed very challenging for the sweeper, and many similar products will have the same problem.
In this environment, the groove height is generally similar to the radar height. The robot will mistake it for a straight wall, resulting in the cleaning mechanism not extending outward and not cleaning in place. We pay great attention to user experience. You can turn off the low collision mode on the APP, open the gap and reach in to wipe. If you can't clean it, you can use a brush to clean it manually.
