I wanted to use this robot vacuum mainly in my bedroom where my dog likes to hang out most of the time. After downloading the app I tried unsuccessfully to connect the vacuum, and it was until the next day when I tried multiple times and it finally connected. I have hardwood floors and two smaller area rugs on my floor, the vacuum was constantly getting stuck on the area rugs, so whenever I decide to use the vacuum I have to pull up the rugs. 
The vacuum does cover all of my bedroom and is great and going under the spaces which I can not easily reach. However a major downfall is that the dog hair tends to wrap and the brush and I have to manually pull off the hair around the brush. 
The vacuum is lightweight and the battery lasts long enough to clean around the room multiple times.
