This vacuum should come with an extra battery.  For the price you pay the battery doesn't last long enough. You need 2 . one for charging and one for using. 
The cannister is extremely difficult to remove to clean it. The design could be better.
Other than those couple of things this vacuum is worth the price of admission. 
The suction is good and the attachments are awesome. 
Better than the Dyson I owned before it died.
