My vacuum is dying. It was fine until I took it in to be repaired. Now it sounds like it's going to lose a part, it's clanking so loudly. There is a vacuum store in town, but I'm a little nervous to take it back to the same guy. Do you think he sabotaged it? It sucks to have dark green carpet that shows every speck of dirt or food. What did our ancestors use before vacuums were invented?
