Roomba is my new best friend. He cleans up when I am too tired and does not complain at all. In fact, Roomba sings a song when he starts and when he is done. Roomba does a better job than I do and gets under the couch and the buffet console. Dog hair and bird seed are not a problem for this tough little guy. The hair and dust is vacuumed up instead of being thrown into a whirlwind of dust to resettle on the furniture and floors. Roomba keeps my house cleaner than I get it an hour before company arrives for a holiday gathering. Impressive. I absolutely love the little guy.
