I decided to make my life easier and buy an assistant, I chose this model. I figured out the connection quickly and the management is very easy. Cleans instead of me really, remote access, I pressed the button while lying on the couch or doing other things and the robot went. Remarkably leaves from everywhere, overcomes thresholds and ideally bypasses all obstacles, cleans absolutely the entire area and corners where it can call. In general, I am very satisfied, it greatly facilitates the maintenance of cleanliness and an indispensable thing in the house if there are pets and a child.
