Bad Warranty Support
Would Not RecommendI purchased this on 2/19/2023 and used the pressure washer 2, maybe 3 times and the pump lost pressure. Even though it is still under warranty Simpson finds a way to not cover due to a claimed "Seal Wear" determined from pictures and they will not cover. I thought it was was purchasing a quality pressure washer but if the seals go bad every couple of uses then they don't have the quality I thought. Would not recommend purchasing this junk.

Worth it
Would RecommendI got my moneya worth I guess, although after a year of using my Simpson pressure washer weekly, I stopped using it because my chemical intake valve broke and I didn't bother fixing it.........correct. Me if I'm wrong but aren't all purchase made via a business account have longer return policys?

Works as advertised
Would RecommendPositives: plenty of pressure. air tires( you want air tires)bag of oil supplied. Negative: outlet bung is directly under dash panel- annoying location. After 3 hours engine time I dumped that original load of oil and replaced it with full synthetic. There's a reason why the throttle lever is so stiff- having used power equipment on plenty of construction and landscape jobs....there's nothing more frustrating then an engine due to vibration powers itself up and down the rpm spectrum. Time will t...

It’s worth the extra money if you want performance
Would RecommendUsed it for an afternoon. It worked well, was not disappointed. However the water hose connection leaked like a sieve during use but didn’t affect the machine’s performance. I wouldn’t think that having it drooling all over itself should be a normal operating situation.

Oil Leak on second use
Would Not RecommendUsed the first day and worked great... wasn't too impressed by the pressure. didn't feel any noticeable difference from my 2800 PSI I had for 8 years. anyway I started noticing some oil gathering but didn't pay it much mind. Used the second time 30 days later and it had trouble starting... the gas was fresh from the pump 30 days prior. The leak kept getting worse...but still didn't pay much mind until the following week there was a big puddle and didn't look like regular oil. Research indicated ...
