as a dog owner ... this product comes up way short. we own the previous 9250 powerbot samsung put out and it is a beast, so much so that we didn't hand vacuum for over 2 years (no exaggeration). with this new jetbotai the engineering team used a soft bristle brush which is not picking up dog hair on carpets. not even a clump of dog hair. not worth the cost if it can't do the basics. this product got demoted to the basement and we brought the older model back upstairs. c'mon samsung, you're better than this.
