Let me check...
It's a Karcher 'Binford' 1650. The one wand has 4 nozzles built in. It really is killer. (Looks like that is a Canada-only model number).
I've used it to clean the windows on the second floor of my house, from the main level. Also cleaned the bricks, sidewalks, decks, hottub, fence and driveway very well. I don't remember what I paid, but it didn't break the bank, and it's held up over a long period.
