I am interested in this mower but have seen what a robot mower with tiny razor blades does. I live in an area that the grass can grow very fast and thick during the rainy seasons and my neighbor had a Husqvarna and honestly the cut was not very good and left long blades of grass. That looked honestly bad.  They finally had to pull out the old mower to properly get the lawn back into shape. 

I would love to see an attachment with proper blades that can actually lift and much the grass. Lymow has one with blades. I would love to have an answer on this because I do love the snowblower attachment but the mower I'm not very excited about.
