The Roomba 690 is a great robot vacuum from iRobot. As you'd expect from iRobot, it is able to get into all of the corners around your house, as well as cleaning the hardwood and tile floors in addition to carpet. It does also feature a 3-stage cleaning system, which will keep your home nice and clean. The Roomba 690 is able to go around your home and clean it for a few hours before it needs to return to the charging station. That should be good enough for most people to get their entire home cleaned with the Roomba 690 before it needs a recharge.
