The best thing about Bob is that he has a big trash can. Unfortunately, Bob is not the brightest lightbulb in the family tree. , Bob is not a particularly bright kid. He is very picky about grooming - for someone who tidies up dirt and hair. OK. He throws a tantrum every time his wheels get stuck in his hair, which happens all the time - he throws error messages every 5 minutes, resulting in me having to break the tool and remove its wheels to pull it off. gets stuck on the edge of a scratching post, on doormats, and insists on getting under a raised food bowl and dragging it all over the floor. When the dog pulls the fluff out of his squeaky toy, THAT gets stuck in Bob's wheels too. If I didn't have any pets, just dirt on the floor, Bob wouldn't be so bad. But I have cats, dogs and children. That's why I have Bob. Call support hoping they can help you.
