I bought during a good sale 6 months ago. I am amazed that it is almost as good as the expensive name brand robot I had a few years ago. It is not as smart, but cleans well and picks up all the short dog hair from our beagle. Best use on hard floors and for picking up short animal hair. The battery has also held up nicely, something that cheap electronics usually short change you on. This one seems to be going strong. Don't hesitate if you can get a deal on this model.
