HK - I have something similar except there are attachments and I can clean anything with it - windows, countertops, microwave, refrig., etc. It is made by Shark and I absolutely love it. It is currently at DBF's as we are using it while fixing up the rental and I miss it.

I am planning on getting a new one that is on wheels as that will be easier on me then carrying around the portable one. That way when I do the floors (and it does work awesome on the floors) I don't have to hold that thing with the shoulder strap.
