Depends on the size of the toy or object. If the object doesn't trigger the sensor that says the robot hit something, it will more than likely push the toy until it does hit something. If the toy won't go under the edge of the robot, then it shouldn't suck it up, but that is a possibility again based on the toy size. That isn't much different than a regular vacuum though. As for moving furniture, we sometimes put our table chairs up, and sometimes leave them down, and the robot seems to adjust accordingly to the changes. You do need to be careful with cords on the floor that the vacuum might come in contact with as those can get sucked into the cleaning mechanism. If the robot gets jammed, it will stop and let you know until you clear the jam.
