This is my first wireless vacuum after a life of corded uprights. I can't believe how great it is - if I see dirt or a ball of dust - just grab the vacuum off the rechargeable stand, vacuum it up and return it. No more unwinding the cord, vacuuming, then winding it back up. Also - if you are used to a corded vacuum like me - this one is so light! Vacuuming stairs has never been easier (or safer in my opinion). It has a spare battery if you have a lot of cleaning to do. I have not needed it yet. The suction on it is great and it is very easy to steer around corners. A great vacuum indeed!
