I bought this vacuum because it was very expensive and I thought that because of that it would be a great vacuum. At the contrary, I cannot use it unless I want to lose a toe, the plastic that kept together the battery, that would click whenever you inserted the battery either broke on the shipment or it was missing. If I try to use it, the battery just drops to the ground and I have to hold it in place. So basically I have to use both hands, one hand on the usual handle where the trigger is and the other holding the really heavy battery so that it does not fall on my toes. So I cannot give my honest opinion on whether it is powerful or how long does it last because I haven’t used it for more than 5 minutes.
