I think it's a husky, must be Girlfriend got it at home depot. It is a 1750 unit. Did not use any cleaners other than just water. It kicks some serious butt!
I have to read the instructions, but I think it has a resivior to house liquid cleaner. On my wheelwell job I pressure washed first, then squirted degreaser in there and used a scrub brush real quick, then shot it again with the washer. The pressure washer works great for removing crud, but it doesn't leave a really clean surface, if you follow up with a washrag or brush, that will work best.
Hey, that might be fun with dish soap. I remember when I was a kid and I put liquid soap in the dishwasher. BUBBLESSS everywhere! all over the floor..
Ah, if you could hook it up to your hot water heater.. hmmm
