Great pressure washer

I shopped for a long time to find a pressure washer that would meet all my needs. Adjustability, durability, and solid construction will make this my long term washer

Great Upgrade

I have had smaller pressure washers in the past, but decided to go with a larger one this time around. I have a dump truck that I wash frequently and this saves me so much time and does an incredible job.

Parts already malfunctioning

I just bought this pressure washer and was cleaning my first house with it and I turn around and a valve on the pump is pouring water and won’t stop, and no it isn’t the thermal relief valve.

Power

I’ve only used once. Everything worked as expected. The only reason I gave it. A four star is because I wish it started with a little more ease, and the first time. I started it and stopped it a few times most times I had to pull a few times.

Excellent power and fires up every time.

I purchased this unit one month ago to take care of ours and our families property and it doesn't disappoint. Very powerful and easy to use. I would recommend this to anyone looking and the quality is great.

So far it’s good

I had a power washer that lasted 10 years when I had to replace it. The past 2 that I bought were total garbage. I did a lot of research and this one seemed to be a good option. Fingers crossed that it lasts. It seems to run smoothly.

Intro to commercial washing

I purchased this as my first machine to get into pressure washing commercially. The Honda engines are well known for reliability and this one should allow me to do any pressure/soft washing job necessary. Great all in one

Nice machine

Got this machine when my DeWalt died. This thing has some real pressure and works well. The handle was a pain to put on because the holes were off by 1/4 of an inch but otherwise it was an easy set up.

Amazing power

This power washer is amazing. It’s so powerful. I cleaned all things in one wash. I don’t have to double wash and it comes with several different nozzles for convenience. It’s a great tool to have.

Smooth and Strong

I previously came from a CRX engine to now my ne Honda engine. The power is smooth and consistent. It is way easier to start than my previous machine. I love it!
