I just received my new AirRam 1984. My previous vacuum cleaner was a Shark. This one from Bissell was easy to assemble, and charged relatively quickly (taking about 2 hours). Relative to my old Shark, I love that fact that the AirRam is cordless with a long charge and is much lighter. It handles well on all my different carpets on 3 floors of my small townhouse. It transitioned very well from carpet to hardwood floor. Cleanup afterwards was also very quick & easy. Again, I've only had the AirRam for a short time but so far, so good.
