I love my Roomba, it is well worth the money for us! We have 1 Newf and another black girl that sheds just about as much. We got new wood floors last year and got a Roomba machine last November to help keep them clean. We love this guy sweeping up the floor every night while we sleep. No longer do I have the hair floating around the floor… I turn it on as I go to bed(quick push of a button), it runs through our great room, kitchen, laundry room and bathroom then returns to the charger and starts again on the timer about 3AM. I also start it in the morning as I head off to work. I hate to admit how much dirt, hair and dust I empty from the tray every morning, but at least it’s off the floor! Every couple days it may get stuck somewhere but we just re-start or recharge. About once a week I have to clean the brushes and wheel, but it only takes about 5 minutes. Also a must have is the added bumper so it doesn’t scratch furniture.
Wouldn’t be without Roomba or the K9III for keeping up with the girls hair and dander!
