if you need a vacuum for your house beware of the shark navigator in some ways it is nice but if you use it in the sewing room where threads wind around the brush or pet hair you cannot clean the roller brush my first one ruined the head in a matter of months and they did send me another one this is the same I called and ask how to clean the brush and they said no way it will not open so I am looking for a new light weight vacuum so any ideas would alsp be appreciated thanks
