Shark AI robot vacuum has become a house friend. It does a great job on hardwood floors, and fair on area rugs. Set up is slightly tedious to utilize ALL features. When mapping, make sure to connect rooms at doorways. The AI will try to go through walls if it can't find the door. Also, not having the auto dump feature with mine, I can say that it is probably worth getting. Overall, I am completely satisfied with getting the robot.
