My philosophy is that at some point, I have gotten my money's worth and 20 years is absolutely my cut off point. I have sucked up the fur of 8 dogs with that baby and it deserves a decent good bye. I have 2 other thoughts. One is I want to move and new appliances are a plus for buyers. Also I would like the biggest, strongest sucking power I can afford. As bad as the last Vin Diesel movie. Vacuuming is my life. Spousal thinks we should spend $$$ to fix it. I don't want to spend a few hundred dollars to find out it's a goner.
