I just received the accessory pack for my HAAN SI-75 today I bought on Ebay. Really, all I needed was that hose so I could use the water tank separately. Now, hoping those darn plastic tabs that hold the hose on the tank don't break off on this one. I mentioned to DH the other day, we might just tape it on and forget the mop part since I've replaced that with the Bissell steam mop with the vac.
They had a nice Bissell one on HSN today as a Weekly Deal Drop for about $90. If I hadn't ordered the accessory pack for the Haan, I might've bought it. DH would think I'm crazy for another steam device, but this thing can be used in ways my current one can't.
