Professional canister steam cleaner - comes with an arsenal of attachments for basically anything you'd ever want to clean. Runs for up to 90 minutes, large 48 ounce water tank. Great for deep cleaning, car detailing, and I was told it's great with cleaning grills/smokers.

Still in original box - I only used it once. The cleaner worked really well, but I live in a smaller place so I don't have place for it. Currently selling for close to $200 on amazon, so it's priced to sell.
