Sick and tired of all the dog hair everywhere and you are to busy to vacuum everyday?, well this will solve your problems. The Roomba is becoming one of the "must haves" for a home. You can set it to go around and vacuum at a certain time of the time. It leaves the charging port and cleans the home and when it is done it goes back to the charging port. It is a smaller round vacuum, so very different from the rest, but works very well!
