Honda GX390 4,200 PSI 4 GPM Belt Drive Gas Pressure Washer is rated 3.9 out of 5 by 41.
Rated 1 out of 5 by from I have to say up front that I can't believe Home Depot would offer this product on their shelves.... I have to say up front that I can't believe Home Depot would offer this product on their shelves. We have purchased 5 of these and each one has had the pump go out in a year or so. The BIGGEST problem, however, is not the poor quality pump but the even worse "warranty" that does not cover what it says. I have been on the phone with the warranty dept of DeWalt and they themselves cannot explain to me why the 3rd party warranty company covering these issues continues to deny the repairs when the DeWalt warranty clearly states that the pump is covered for 2 yrs. Apparantly the 3rd party warranty company is telling the service centers that anything over 1 yr is not covered. I was told the warranty for these machines was 1 yr right off the bat from the service center on 2 separate occasions only to have the DeWalt warranty dept call them to correct them and they STILL are denying the repairs. To this day, no one has told me under what basis the repairs are being denied other than that the 3rd party warranty company is denying the repairs. So to recap, I've spent $1200 x 5 for pressure washers that only worked for a yr. Not worth the money or the frustration. There are plenty of other pressure washers out there priced better, are better quality and whose warranty is backed by reputable companies. You have been warned.

Having recently purchasing this pressure washer to clean my patio and driveway,since the hose doesn't seem to do it well and wastes water, I found that it has exceeded my expectations. This pressure washer was perfect as it allowed me to clean my patios, walkways, brick and fences. The unit was easy to start up out of the box and so far I haven't experienced any issues. The Honda engine and AAA pump seem so far to be a good and reliable combination.

Rated 5 out of 5 by from Powerful and reliable pressure washer I recently brought this pressure washer and it has exceeded my expectations. This pressure washer is the perfect addition to my equipment for my business. This unit has cleaned several driveways, patios and parking lots. The unit was easy to start up and i haven't experienced any issues. The Honda engine and AAA pump are powerful and reliable.

Manual says that the washer should run at 4100psi, it is running at 3800psi and I see no way to adjust. This washer does not perform as well as my 3500psi washer. If I have to take the washer to have it adjusted or repaired I will lose time and money to try and get what I thought I had bought. I am upset to say the lest. Jim

Started-up on 2nd pull and runs smooth, I am satisfied with the psi and the gpm really put out some cleaning power! my foam cannon attachment is a blast to use with this machine. I also have the 2.5 gpm dewalt pressure washer and I would rather have this $1400 4200/4gpm over two of the $700 ones.

This is a powerful pressure washer that cleaned my driveway and patio beating away grim that was building up since 2005. The only real issue was that the spare nozzles kept vibrating out of the holders. Need a bugging strap to keep them in so they don't get lost.

Rated 5 out of 5 by from Best pressure washer by far My family and I own a farm and a pressure washer is a normal tool we use. The product arrived in perfect condition, as I expected. Some easy assembly required and then you are ready to use. Best value pressure washer on the market, reliable every time.
