Did a lot of research and wanted a good vacuum for pet hair. It came down to the XXXXX and shark. The shark is just light years ahead of 'cheap' vacuums. Couple great things about it..shipped fast, simple to assemble, easy to maneuver, has a bunch of attachments, can turn the beater brush off/on, don't have to adjust the height when on bare floor or rug. Only small issues..was missing a screw that holds the top handle in place, a lot of attachments (which is nice) but there's not a place to put all of them on the vacuum.
