Vacuums are a major source of income for me. These people toss out high end units that have several parts that constantly sell in the $50-$125 range. Miele and Electrolux are the most common top brands here, and Shark parts sell like water in the middle tier.
I have a bunch in the queue to list once I get back on my local schedule here. I could sell them as a complete vacuum set, but it's more profitable to sell them as parts. Most vacuums are perfectly fine, but just have a clog in them. Worst case, maybe a hole in the hose... plenty of reason to toss them right?
Duct tape! :D
Amazing what can be done for the environment with a little bit of elbow grease to bring things back to life.
