Have had great experiences with Roamey thus far. I will be fair in that she got herself stuck behind the couch (still not sure how got back there.) and a small area between the shower and lavatory. Other than that has been a champ and the amount of debris she gets is amazing. I always thought we vacuumed well but she was able to show us differently. We have two cats and no problems with hair. (We do have three girls with long hair and picks it up no problem.)
