I have tried several different robot vacuums and was never super impressed by any of them. We have a dog and 2 toddlers that leave messes all over and all the other robot vacuums couldn't handle the hair. The Roomba Combo does the most amazing job getting all the pet hair up and all the little crumbs and messes my toddlers leave. The best part is that it doesn't get stuck under furniture either. I can extend vacuuming now to once a week when I previously would need to vacuum twice a day. I'm beyond thrilled with this vacuum and have told all my friends and family to get one.
