Elis vs Roomba This type of behavior is common, also seen with brooms, rakes, lawnmowers, cars, other types of vacuums, and anything else that moves and make noises. Some might think this is funny and will encourage this type of behavior, please don't!! Not healthy at all. This entire session was only 15 minutes, now if only purely positive methods were used, it would have taken 15 weeks, medications, calming blankets, euthanasia, etc...🤣 NOTE: No Roomba was injured during this training session
