Full Disclosure: After being married for over 10 years I did what I knew was wrong and bought my wife a Roomba for Christmas. But you readers don't know my wife, she loved it! Okay, I know some of you guys are saying I could get up from my seat and help with the vacuuming. I did my fair share for those who wondered. So yes, I was selfish in buying this gift. Our Roomba was wonderful. He did a great job and all the woman had to do was push a button. After all, it was "her" gift. I am a child. I am a child. Seriously, this is one of the best products I've ever bought, but the cleaning wasn't up to the manufacturer's standards, so we needed replacements. This product is exactly that. It was a great award and I was appointed for a few more years. The parts fit perfectly and were easy to swap out. Advertising is present in what you get. It only took me a few minutes to swap out parts and try it out on my office floor. It worked great and still works. Our only problem is finding Roomba when it shuts down because it's stuck somewhere. On the other hand, I was selfish and bought a cheaper model. With the parts included, we won't have to buy this product any time soon. But I will buy again if needed.
