I have nothing negative to say about this light in weight but heavy duty machine. It is powerful enough to thoroughly clean all of my rugs and runners in one pass. I love the fact that it has such a long charge that I can cover the three floors of my house with plenty to spare. With my limited storage space, it is such a bonus that this vacuum can be compacted down to such a small footprint. The only thing that I can add is IT IS A WINNER.
