This is equipment used for homebrewing beer and winemaking. It's used to clean bottles before bottling and small fermentation vessels. It can wash two bottles at the same time, which makes the work go super fast, and is recommended. Made in Canada, so you'll need to get some connection parts from a hardware store to connect it to your faucet. I bought several of these a few years ago and have kept them new and unused. The packaging isn't perfect, but they are unopened. Thank you. Search YouTube for how to use it ↓ Fermtech Double Blast bottle washer
