It's great to hear you were up and running in no time, & your 4400 PSI pressure washer is performing to deliver all the power your need and then some. Show off your projects any time by tagging #simpsonclean on social media and we'd love to see the results you achieve. We appreciate the review, Ken!

Awesome unit.

A little bit harder to start than my old Honda, but works great when it’s going.

Not your Granny's power washer.

This machine is the real deal. From the brass fittings to the HD rubber hose. An amazing outfit.
