A self-sufficient, monitoring-free, smart robot vacuum. Wool is great for keeping tiny particles like hair and dirt at bay. Overcomes obstacles with ease. Excellent buy; I'm very satisfied. Six months ago, I made the investment and now I use it nearly every day. And then I was disappointed. offers benefits: Powerful suction (lifts even heavily trampled pile). Intelligent guiding systems. Produces a map. Easy to implement. User-friendly design Cons: Doesn't tidy up the area surrounding the charger. This is not a knockoff
