I looked into getting one a few years ago. The best price I could find after researching was at Kohls when they have the 30% off coupon on top of a sale. I researched reviews and I decided not to buy one. I have a sunken living room (steps down) and I would have to buy a beam thing that prevents the Roomba from going into the living room, because if would fall down the step, and other rooms where i didn’t want it to go, I’d have to buy the beam for that, too. The beam was about 80 dollars at the time, for each one, so when I added that to the cost of the Roomba it wasn’t a good total. I think I also didn’t like the idea of a thing running independently, possibly getting stuck somewhere and just whirring and whirring and getting hot, possibly blowing the motor.
