A:AnswerYes, the battery is rechargeable BUT you will need a proper sized transformer to correctly charge it at 120 volts. The battery also senses when it's too warm, and thus won't charge till it has cooled down a bit. It does that on its own, as fully explained in the owner's manual.
A:AnswerYes! You do have to go over fiber dust particles twice sometimes but I have vinyl plank throughout our home and have absolutely no complaints with this vacuum.
