This is a very powerful pressure washer with more than adequate gpm water flow. The GX390Honda engine gives me great confidence of many years of reliable service.

I bought this a little over a week ago and what a difference it has made. I've used it to clean driveways, houses, cars, garage floors, fences, and so much more. Absolutely love it and how much faster and more efficient it has made me.

The pressure washer is has more power than anything I need it for, and I can adjust the pressure down for a gentler spray. I upgraded from a 3300 psi and am happy with the bigger machine.

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.

This washer is very powerful so be careful. Just remember that if it doesn't start on the second pull you'll feel it get harder to pull, pull the trigger and release the pressure. So far love it.

Bought this to start a pressure washing business. It might be overkill for your personal drive way, but for commercial work it does a good and effective job.

Unboxing and set up was fairly easy and no damage was discovered even though the box was not in the best of shape. All parts were included and it’s all set up and ready to go.

Brought this month for my small business. Works great and gets those tough stains out. Easy to use and feels great. Good quality machine for recreational or commercial.

This is my second year with this unit, I still give it a heafty five star rating. Pros: - Honda kills it with thier easy start feature, one pull starts. - The Honda GX390 Commercial Series OHV Engine is thrifty on gas...runs smooth as well. - The overall package is well balanced and easy to move around...perfect size and quality of tires. - Very rugged construction, the unit is built to be worked. - Well balanced (but heavy) if one needs to pick it up and put it in the back of a truck bed. - My unit came with the Comet pump, zero complaints. Cons: - Attaching the garden hose was awkward for my large hands (to close to the motor and under the pressure hose coupler) so I extended that connection point just outside the frame and yet still is protected by the tire. Connecting the garden hose is now simple. - There is nothing to complain about with this machine, but I guess if one has to say something negative....the hose does not like to swivel at the wand*, therefore one has to wrassle with the stiff hose when changing the orientation of the wand. Overall: Love the 4,200 psi w/ 4 gallon feed, I don't use it always, but I have it when I need to get serious. I also really love the 4,200 size because it allows me to run 100 - 150 ft of hose and still have pressure at the nozzle. * One day I'm going to have to buy the proper high pressure swivel for the hose to wand.

Bought this pressure washer a few weeks ago and couldn’t be happier. Did quite a bit of research and this guy was the most bang for my buck. Definitely potent for a homeowner, but gets the job done quickly. Honda engine started on first pull and pump seems to be of good quality as well. Very happy with this purchase.
