I love My "Henry" I Have the Roomba 560 I call her Mable and now with the addition of Henry My floors are always clean. I work about 60 hours a week and it was driving me crazy seeing my floors always needing mopping and no time to do it. i set up Henry at night and wake up to nice clean floors. I use Henry about 4 times a week and Mable every day between the two of them my floors are always clean. Wouldn't want to be without them!!
