I love this cordless vacuum mostly because it is lightweight but also because it has many great features. The way it automatically adjusts the suction needed is great so you can go from carpet to floor without having to turn it off and switch. I also love the LED display to let me know how charged it is. This is a great vacuum for an older person also, my 80 year old mother lives with us and she loves this vacuum because it is so easy to use and because it can get under furniture easily she doesn't have to move the furniture out of the way. 
This vacuum also folds up nicely to store it in a closet.
