When QQ-1 gets into a tight spot, it will usually find its way out after some times. We recommend that you watch QQ-1 the first couple of times you use it, so you can see if there are cleaning areas where it gets stuck, and move things and set up barrier as needed. Because QQ-1 lightly bumps walls and other objects as it cleans, remove any light items that may be pushed or knocked over. Of course, you will get better results if you clear the floor of any loose items before cleaning, just as you would if you were using a traditional upright vacuum.
