Received Jan 26, 2013 finally charged on Jan 28, 2013, lasted about 12 minutes.Was able to use again on Feb 7, 2013, battery lasted 5 minutes.Put back on charger, used again on Feb 12, 2013 and again battery lasted 5 minutes. This is terrible.Doesn't last long enough to barely clean one room and then you have to wait AT LEAST 24 hours before you can use it again. Wish I would never have spent the money for this.
