Nice pressure washer but keeps auto shutting off.

2 months ago

I have been fairly happy with this purchase. After assembly and prep I was able to get it started right away. I used it to clean for 3 hours that first day with intermittent stops and starts. There was a problem that it kept shutting off by itself. At first I thought it might be out of gas but there was enough to keep it running. I let it cool down and then it would start up again. I put more gas in it as well just in case. It seemed to run for about 40 mins before shutting down. Also, the gas tank on this model is way too small. When it is running it is great. I still don't know if it is an automatic shut down. Pressure is great. The connecting hose and gun do not leak. It did come with a manual for the engine but not for the washer as a whole for assembly or operation. I was able to figure it out.

Yes, I recommend this product.

Amazing power washer

9 months ago

The Karcher G 3400 P was packed up nicely in two different boxes. It was easy to assemble. It cleaned our driveway really well! Though it’s really heavy the wheels on it makes it really easy to move around. The only problem I had with it is that there’s no directions on how to put some it together and had to look online to see how much oil to put in it.

Impressive cleaning power

I received Kärcher 3400 PSI Pressure Washer free from Influenster in exchange for my honest review. When I first removed from the box, the quality felt solid and durable. Setup was easy and took less than 15 minutes from start to finish. The brass water connection is well made and makes connecting the hose easy. I love the 4 quick-connect nozzles that makes switching the spray pattern easy, depending on what you are cleaning. The engine starts on the first pull so you are up and running fast with no hassle. I tested it out on my sidewalk and couldn’t believe how effortlessly it cleaned every stain. The pressure is strong enough to cut through the toughest dirt and grime, but still easy to control. The bigger tires make it easy to move around, rather it is on grass, pavement or rocks. I found the hose was long enough to allow you to clean large areas with ease, without having to constantly move the whole unit. If you want something with heavy-duty cleaning power and dependable results, this machine is the way to go.

Powerful enough for any task

What a powerful workhorse! Great value for a pressure washer of this quality! This washer cut through all the dirt and grime on my sidewalks and driveway like butter! Love the trigger safety and the ease of using the pressure washer. Easy to assemble and was up and running in a few minutes. Best feature is the wheel position, makes movement and placement of the washer so easy to use and store.
