Update: corrected the rating. The company has contacted me and is doing their best to help me resolve this issue. They kept in touch with me and were vigilant in responding to emails and step-by-step instructions. First, I can't connect the device to my WiFi. I tried to contact the company and they sent me a youtube video. I tried that but it didn't work. I've tried to contact them again a couple of times and I haven't received a response. Such lousy customer service. Second, the suction power isn't great. I really think he needs 2 brushes, I've noticed he misses what isn't swept with a brush. So the suction power of the vacuum cleaner is not strong enough. i can return it He didn't decide.
