We seem to go through vacuum cleaners like no one's business. Over the past 20 years, we have had some stop working that were rather expensive. Dyson, Shark, etc., it doesn't seem to matter. We have an old-timey hoover with a bag from the 1980s that my wife's grandmother gave us, and it still fires up when called up from the bullpen. I guess they don't make 'em like they used to. What vacuum do you or your servants use, and long has it been plugging away? Looking for a suggestion on a quality one that will last. TIA
