Bought mind at COSTCO which had the best price around, a 2400 psi it's a Karche with a Honda 5.0 engine. Will knock the snot off anything. I bought it last summer to power wash the deck (about 2400 sq.ft.) but I haven't used it much. I unpacked it, set it up and the wife wanted to try it...the next day the deck was finished and looked like new !!! grin I've power washed a couple of engines and was very pleased with the results. This year, I'm looking to get her a John Deere lawn mower. Nothing but the best for the wife grin grin . Good luck.
