I have an earlier version of this and the newer one has some improvements. More powerful than the first one and equally light in weight. I like having the longer lasting battery, too. Also, the controls up higher on the handle are an improvement from the older version but occasionally my finger will inadvertently shut it off - maybe designers need to refine a bit. Expensive, but overall a good product. Wish your hardfloor product were a better performer. Get a really good product designer to work on that. I have two but really wish performance was better.
