TBD

Purchased due to Simpsons reputation for quality. I sold Simpson PW starting in the 80's and prefer them over other brands.

Clean and easy setup!

Everything about this pressure wash is very professional. If you looking to upgrade to higher gpm without breaking the bank, this is the one!

Pressure Washer

Lots of Power in a lightweight package. Comet pump oil works great in my opinion ; when necessary to change pump oil.

Great power

Great unit, bigger motor so a few more pulls to start than my smaller one but the adjustable pressure is great, and runs good and strong so far!
