I do not care for Generac. If you check deeper you will find that a Generac Pressure washer was pulled from all Lowe's stores last year due to problems. Just fyi.
Whatever you get, be sure to get the tip kit. Its great. I personally would not want any psi other than 3200, but then I use mine for commercial use and it does do all the jobs. Just back off the work if its too strong and use the fan tip.
