I have 4 large bitches. This vacuum cleaned my entire 1300 square foot house and still had 80% battery left. I love how it automatically adjusts the suction power for hard floors and carpets. Dog hair is not suitable for this vacuum cleaner. Set up was easy as the holes for the dock lined up exactly with the holes for my Dyson V6. I am 65 years old and had no problems unpacking and installing. I wish I could give it 10 stars.
