I purchased this vacuum cleaner mainly for frequent use without dragging the cable and attachment of my canister vacuum. This AirRam does exactly what I anticipated and I am satisfied with its performance. The suction is fairly powerful. The vacuum is not designed for cleaning the edges but the opened areas. My only complaint is I cannot purchase a spare battery online. It is out of stock. I wonder if Bissellll is planning to discontinue the battery and this AirRam. If my battery dies, this AirRam will die with it!
