We have two Labs who shed as if they’re being paid to, so having a robot vacuum cleaning up after them makes me really happy. We’ve named her Rosie, after the robot housekeeper in The Jetsons, and even the dogs like her, seeming almost mesmerized by her as she quietly goes about the family room doing the household chore I least like- vacuuming. The Roomba works as well on thick carpet as it does on hardwood floors. The reason I deducted one star is because understanding how to make the vacuum do what I want isn’t as user-friendly as I would like, but, overall, I’m very pleased with this robot vacuum.
