Th is vacuum cleaner is absolutely the best on the market.  It is perfectly made.  It has all the attachments you will ever want or need.  The powerhead makes all my carpets look brand new and it is powerful.  It is quiet and just a joy to use.  The battery life could be a little better but this one does come with the extra battery.  Charging time does not take to long.  If they come out wth the replacement batteries they will beat dyson hands down.
