I returned the first one I received because it didn't charge or charge and sincerely hoped it would so was just out of order. Unfortunately, this one has the same problem, only lasting less than 10 minutes on one charge. In addition, the suction power is very poor. I use it almost exclusively for cleaning car carpets and it absorbs next to nothing. Also, the fold out extender/slot tool worked very poorly. I intend to ask the Revain for a refund and a stronger one as I plan to use it to clean the carpets in my car and such.
