Both new robo-vacuums will go on sale in Europe and the US in early October, with China and Japan coming later in the year.

As before, Neato's main advantage over rivals remains its laser navigation. The new models continuously map your rooms and detect objects in real-time, helping them adapt to room conditions and clean in straight lines. We found the high-end Botvac Connected roughly equal to the more expensive iRobot Roomba 980, albeit prone to catching on cables and furniture. The lower prices make those quirks a little more forgivable. While the whole point of a robot vacuum is to clean while you're off doing something else, you might not mind babysitting the D-series Connected models for the money you're paying.
