Best advice I ever got on household vacs, (not shop vacs) is buy an old Hoover. You want one from the eighties or earlier that has all metal parts. A little heavier than the crap they sell today but its made in Emerika, by people who might have, maybe, given a damn about the quality of their work. I inherited mine, and its a winner, the guy at local vacuum repair place concurs they are what to get, they are not disposable. Mine is an upright with power drive wheels, and wait for it............................. It sucks!!!
