Great Pressure washer strong and consistent

10 days ago

This is my first gas pressure washer but I am really pleased. Having high pressure an high gpm was important to me and electric pumps were not working for me. I have used this to wash my house, cars, and drive ways without any issue.

Alot of trouble

13 days ago

I bought this pressure washer brand new, got home open the box and try the electric start. It doesn't work. Cant figure out, so a neighbor came over and diagnosed, it's the battery. Have the battery fully charged and electric start works. Use it for 2 hours that day. The next day use it for 2 hours and electric start does work again, check battery and it's still 100%. So we use the recoil. Use it for another 2 hours and no pressure. Have the neighbor came over and diagnosed again, he says it's the unloader valve (regulator) that's stuck. Now, I cant even use it.

Simpson Team

Hello, Luke1978. This certainly isn't the performance we expect, & we're sorry to hear about the electric start/unloader valve. At your earliest convenience, would you reach out to our team directly at 877-362-4271 or email us at productsupport@simpsoncleaning.com? We hope to learn all we can about the condition of this unit so we can get you up to peak performance as quickly as possible. Thanks for sharing your experience & we hope you will be in touch soon!

Love the electric start

13 days ago

This this rocks! It's very powerful and will do any job I ever need it to plus as I'm getting older having an electric start is a big plus. I'm tired of pulling cords but need the power of a gas powered sprayer. This beast solves all possible issues. I hope the battery lasts awhile.
