<span style="font-family: tahoma,arial,helvetica,sans-serif; font-size: medium;">When I saw the thread title, I thought you meant a hose for the Electrolux Oxygen vacuum. </span>
<span style="font-family: tahoma,arial,helvetica,sans-serif; font-size: medium;">I like proper descriptions too, but its better to state you don't have much knowledge about an item, rather than pretending you do, or copying the information from another source, as has been seen on Ebay in the past. I'm guessing by "central vacuum motor", the fellow meant "main power unit", or something like that, although the "oxygen hose" is a little bit ridiculous, I admit.</span>
<span style="font-family: tahoma,arial,helvetica,sans-serif; font-size: medium;">Nothing wrong with making a profit on Ebay, either; that's the whole point of it. I will say, however, that Ebay sellers do need to be as careful as possible with their descriptions, considering the buyer pays up front and any problems are only discovered after the sale is complete. With Kijiji, Craigslist, etc, it doesn't matter so much, because you can see the real deal before spending the money. </span>
