Great Quality

This has the Honda engine. Starts easy and runs great. Surprising pressure. I’m very happy with it.

Great Purchase

I bought this ALH3425 GX200 Pressure Washer to remove 5+ years of Short-Well very dark rusty stains from my sidewalks & driveway assisted with the Simpson Surface Cleaner. I sprayed Oxalic Acid (12 oz. /gal) first & waited about 10 minutes before pressure washing & removed 99% of the stain. Very satisfied with the power & ease of use!
