UPDATE : after two month of use ... I give it five star again . people , this be for small clean up job not vacuum whole home !! here be a tip . after you have cycle through five charges\/discharges keep it plug in full time . so you use it for say two minute , plug it back in . keep it plug in and it will always be ready . original review : if you plan on use this as you only vacuum you will be disappoint . for smaller job this thing rock ! the pet hair tool really work ... be a bit skeptical it could lift up month of thick cat hair but no problem . battery life be 10 + minute and I have only cycle the battery a few time . 10 minute be actually a fairly long time for most job . it be light , the tool do they job , it be powerful ... five star from I !
