It's been 2 months since I purchased this little robot (which I called Jim) and I do not regret my purchase. Quiet, intelligent and goes everywhere, I have not spent the broom since I adopted (though I have a cat that leaves fur mounds everywhere)! The mop mode is surprisingly effective for a 50m square apartment. The wipes are changed and cleaned easily. My friend who was very skeptical was quickly conquered by Jim. In short, very good product.
