Unfortunately, all hoovers with camera and 3D recognition have this problem when objects are not very high. The database in the robot probably has no idea what kind of toy object it is and if the objects are only a few centimetres high and very small and not very wide, it rattles over them. Unfortunately, the front bumper can't be triggered either because the little toy offers too little resistance. I would make sure that the latest firmware can be installed, because this is usually how you optimise your hoover. But you can only do that via the app. What else you could do, there is the option of displaying photos in the app of what it detects or thinks it detects. You could still see what detected or non-detected objects are mixed up with. However, you can also simply set up a prohibited zone in the app, where the track is usually located, and then he would drive around this zone.
