Customer Reviews:
Came on time, packaged well, easy to use. I have only own iRobot’s before, this does a great job so far. Always makes it back to the dock. App easy to use. Quiet, I have two cats and a dog, it picks up the hair no problem. My only complaint is long hair wraps around the two front brushes all the time. It’s easy to remove. One thing I really like about this robot is it goes on my black area carpet with no problem, my iRobot’s won’t go on any area rug that has dark designs in it. This robot does. Plus the price is 60% less than iRobot’s. Well update again in future about this product.
