This washer was an upgrade from a 2800 psi washer I had. The increased power and GPM cut my hard tasks in half. Cleaning my driveways with a 20” surface cleaner went from 8hrs to 3hrs! The ability to adjust the pressure is a game changer.

Great power washer, gets the job done! Highly recommend!

That's great to hear, Steve B. We are glad to know your 4400 PSI pressure washer has delivered an impressive power upgrade and it performed in tandem with your surface cleaner to make short work of such a big job. Show off those results any time by tagging #simpsonclean on social media and we'd love to see what you achieved on that driveway. Have fun tackling your projects and thanks for the positive feedback!
