Best pressure washer of all time-Simpson.

[This review was collected as part of a promotion.] I have other Honda powered Simpsons that also work very well. I love this new machine.

So far so good

Fast attic results during first week of use. Pay close attention to non or treated ethinol gas for longevity.

Great design

The ALH3425 is a great size for home projects. Would like for the wand holder to be more robust. The HONDA engine runs great.
