What Customers Are Saying

The pressure washers have a mix of positive and negative feedback. Customers appreciate the powerful cleaning performance, convenient electric start, and versatility. However, many have experienced reliability and quality issues, including pump or motor failures, leaks, and poor construction quality. The reviews suggest the performance benefits may be outweighed by the risk of significant issues, and proper maintenance is crucial for reliable long-term use.

Real good but

Would Recommend

The hose holder is very cheaply made as well as the battery case which I fear will have a short life. Also the battery is just below where water could leak on it. Starts great.

if it starts.....

Would Not Recommend

we purchased this unit for the high PSI rating, right out of the box the unit would start on the first pull, but if you shut it down it would not restart after breaking your shoulder on the pull cord, you would have to let the unit cool off for 24 hours and then it would start on the first pull but don't shut it down because it will not restart for a full day, emailed Generac about the issues never heard back from them, emailed the company i purchased it from and nothing but crickets, called a d...

Electric Start is the way to go!!!

Would Recommend

After having pull starts on previous pressure washers, I opted for the electric start. So easy and convenient. The unit has an pull start too - in case you didn't charge the battery.

Buy direct from Manufacturer

Would Not Recommend

Don’t be like me and overpay for this unit. Do yourself a favor and save $200 buying directly from the manufacturer Generac at $299 for the same exact pressure washer.

The soap dispenser cap not good it leaks.

I like the white tip I get more work done with the white tip. The other tips doesn’t seem to have a good flow the soap dispenser cap. I do not like because fluid can run out of it if you’re not using it but other than that this is a great piece of equipment.

Not weathertight...

Would Not Recommend

The washer works fine, IF, you don't leave it out in the rain. The first time it got rained on it was hydro-locked! Water somehow found its way into the engine and blocked it up tight. I removed the plug, ran the starter, and sprayed a little oil into the cylinder. Again ran the starter... Then drained the crankcase oil and refilled it. I ran it until I was happy with the hot engine... Be sure to keep it dry!
