Honda GX390 4,200 psi 4 GPM Belt Drive Gas Pressure Washer is rated 4.0 out of 5 by 20.
Rated 1 out of 5 by from First one DOA.... wouldn't start. My first Honda engine with any type of problem. Ship to store n... First one DOA.... wouldn't start. My first Honda engine with any type of problem. Ship to store not a great experience, as the freight company to my locale did it promptly, but then the shipment disappears into a black hole until the store finally gets it, unpacks it and notifies you. Would never compete with Amazon.

Rated 4 out of 5 by from Very Powerful, good value After 20 years of light use, my 3200 psi pressure gave it up. The new De Walt pressure washer has plenty of power and was easy to assemble. I went with the belt driven model in hopes of extending the life of the pump, which has been weak link in a pressure washer. I also purchased the garden hose inlet filter as additional insurance. Very pleased with the purchase. Would have given it five stars, but the instructions clearly state not to use chlorine bleach products as a cleaning agent, so I was unable to use my Jomax-bleach solution that is really needed for mold and mildew on the Texas Gulf coast. The ZEP pressure washer safe siding cleaner does not get the job done. When using an 18 foot telescoping wand, the pressure needed to remove mold and mildew without a bleach solution makes control unwieldy.

Rated 4 out of 5 by from very good homeowner unit Bulletproof engine and belt drive to reduce the temperature and vibrations at the pump. But last years model had an external pressure relief system. This one is internal and that was a surprise to me. They also switched from a general pump to something else, and the general is known for its forgiveness in not scavenging the supply hose if the flow is inadequate. Still, for the money, its the best belt drive out there. It also has no external incoming water filter, and that is something I find mandatory. Its only a few bucks to add so its not a deal breaker.

Rated 5 out of 5 by from Excellent Machine (noobie here. It didn't start) I purchased two. The fist unit, I was unable to make it work. Reviewer here named "Builder" appear to have had the same problem. Because the unit is not sold at the store and I couldn't wait, I had to order a second one. I had the same problem and it didn't start. At that point, I knew, it's either a terrible product or I'm doing something really wrong. I found the instruction contradicting each other. There are two sets of instructions. One is for the pump and the other for the engine. That was NOT clear to me (first time using a pressure washer and not much experience with gas machines). The instructions said "make sure each time, you check the oil is OK. There is a dot make sure oil is up to that line". Instruction also said, for your convenience, we have already filled it up with oil". So what's the problem? The instruction did not say "make sure BOTH sections of the pressure washer need oil". The instructions did not make this clear. When I checked the oil, oil was fine but there was no engine oil in the machine. Therefore, the machine would not start. I took it to Home Depot and the guy (manager) tested it and couldn't find anything wrong with it so I returned the first unit. I needed a machine so I ask if there is anything else I can try with the second one that I have in my house. He suggested to take it to the larger Home Depot that have a repair center. The guy there checked and asked, "did you put oil?" I said, the instructions said oil has already been added and to check, which I did. Then he said, "what about the engine oil?" and I said "what?" At that point, I just want to put my head in a bucket and hit myself with a brick. He added oil and without the choke pull the trigger and the machine started. Took the machine back home, with no choke, I pulled the trigger and the machine started just fine with one pull. I re-started it multiple times since and it only needs a single pull. Lots of power, easy to start, HEAVY but has wheels. Love it! I just hope it lasts for a while.

Rated 5 out of 5 by from Got the power Well pleased with this washer it has great power. It is heavy and you will need help to load in truck or ramps.

Rated 5 out of 5 by from Great features and price This unit really gets the job done. It's more compact than some other belt drive models that I looked at. I had some entrenched algae and mold on a wall where rain splashed up on it and this unit got into the stucco deep enough to get it out. The only improvements that I can think of would be to make the handle removable and make the wand holder such that it holds the wand up above the tire. It would also be nice if they offered a hose reel, as an accessory--a simple one that would just store the hose would suffice.

Rated 5 out of 5 by from It is well made It is easy to use and has alot of pressure. It's great that you can adjust the amount of pressure to what you need. I have used it to remove paint on brick walls, and to clean our sidewalks and store fronts.

Rated 4 out of 5 by from Research Pays Off! I had a Karcher 3500PSI Honda Engine for many years, constantly broke down (the pump). Finally decided to try this model. Did a lot of research. Warranty, price, PSI, and its from a company that should backup the product (both Dewalt and HD, yes I know its not made by Dewalt). Used the machine for about 15 hours continuously so far. Results, this is a powerful machine, and seems lightweight for the capacity. The wand uses the plug in's for pressure control width and intensity. Unfortunately, I do not see a valve to control water flow. There is a valve to control detergent flow. Frankly, for the price you aren't going to beat this one. The warranty seems good given that the pump units are prone to breakdown. Instructions were poor. Overall, I am so far pleased.
