Amazing power

This pressure washer lifted my surface cleaner off the ground. It is heavy duty yet pretty movable and lightweight. Highly recommended!

Just received this PW, assembled it, put gas and oil in it, have not used it yet. Looks sturdy and built very well.

Incredible

Couldn’t be happier with the unit, previously had a 3100 psi and wanted the commercial grade of this unit of 4400.
