About 25 years ago, I spent what seemed like a lot of money with a friend who sold commercial vacs to purchase for my household use a Sanitaire vac, the commercial make of Electrolux.
Earlier this year, the zipper on the bag gave out and I though how silly it was that such a simple part should be the death of it, but 25 years is a long service. I took it to a local repair shop expecting to be laughed at for having such an old thing.
"Is next Tuesday ok?"
"What?"
"Well, we're awefully busy and one tech is out having a baby. I don't think we can get to it much before that."
"You can repair it?"
"Oh yeah. No problem. We can replace the bag, and give it a full overhaul for you."
"The parts are still available?"
"Sir, look to your left and a little behind you, that blue one for $950..."
"Wow. That looks almost exactly like mine."
"It basically is. They've changed the logo a bit and the new ones have different, actually better, heavier-duty cord. But everything else is the same. It's a classic, a great model. We sell a lot of those."
"$950!?! I think I paid $400... and that seemed like so much to spend on a vacuum at the time."
"You made a good choice. We'll fix this bag... and your belt looks a bit worn... and these brushes are getting on... for about $100 and it will last you another 25 years... at least. These things are really well-made. Basically, these things are made to be used 16 hours a day, five days a week. If you're using it for 20 minutes once a week, it'll last forever."
So, my advice to you is this: buy quality and you'll only cry once.
