The best vacuum for cat hair and even dog hair is the Roborock S5 Robotic Vacuum and Mop cleaner because it is dual purpose. Additionally, the super suction function is very powerful that it can pick up hard-to-reach dust, pet hair, and other debris from the floor. It will navigate the room and even go under your furniture, and if you turn the mopping mode on, then it does both. You can rely on it not to leave any streaks because it will mop it off.
