I wanted to try a cordless vacuum. This one had good reviews and attractive features. 
The good: The anti hair tangle feature works well, the vacuum cleans well on hardwood floors, the powered lift away is great on stairs. 
The bad: although it does well on debris on top of the carpet, it doesn't do a good job getting dirt in the carpet. The battery says 60 if you run it on the lowest setting, but if you actually want to clean, it barley last 30 minutes. I can just barely clean my apartment before I need a new charge.
