Powerful, Well Designed And A Generac
I researched pressure washers very long and hard to replace my 10 year old Porter Cable 3000psi that wore out after hard use.

As I have a Generac 8000 watt generator and have been pleased with the brand that is US made, and that Bill Mikenis said "
The 5997 has been moved up a spot in our Recommended list due to its proven performance- we have received a lot of positive feedback on this model. This pressure washer includes a Generac OHV commercial grade engine and an AR triplex pump.... more

Great Price But Not For Contractors
This is the least expensive 4000 psi that I could find so I bought it. Now one year later I regret it. It seems that the frame and assembly is too light weight to hold this powerful engine. Screws were falling off, severe shaking. After 3 uses things were starting to go wrong, pressure was weakening....slow to start....oil leaking from gasket...etc.

I tried to start it to wash a driveway and it won't start. I'm going to need to buy a new unit, but I won't be going the cheap route this time.

David,
We list this unit as Prosumer grade- which means it has heavier duty components than a regular consumer-grade model. Prosumer units are great for homeowners who want to buy quality equipment, and business owners who will use it occasionally.

This unit has a 3 year, consumer-use Factory Warranty from the folks at Generac. I didn't find a listing for you in our database, so I don't know if your pressure washer is still covered. If it is, you may want to use the Generac Service Locator to find the Authorized Warranty Service location nearest you.

You will need a copy of your invoice to bring to the service location. If you have other questions, you can call Generac directly at 888) 436-3722 x5381.

We've gotten reports about only a few units with vibration issues, and Generac has been able to to solve them.

Problem After Problem
When I first got it I thought it was going to be a good pressure washer but have been very disappointed. After a couple weeks of having it, the plastic rope carrier for the recoil broke so I had to bring that in to get it fixed.

Then it worked well for a bit but then the real problems started. Anytime the pressure washer would be under a load (holding down the trigger) it would run for about 30 seconds and then it would bog down and shut down every time. So then I brought it to their... more

Jonathan,
If the unit works at the repair shop but not at your house, the problem may not be with the unit. You may want to check your water supply. If you don't have enough back pressure (volume of water) flowing in, the pump will not work properly.

This can be caused by using a garden hose longer than 50 feet; it can also be caused by using a well that doesn't make enough water to keep up with the pump. This pump will not self prime, so it should not be used with a water tank.

Warranty repairs are covered for defects in materials or workmanship. The warranty will not cover repairs for wear and tear, or abuse- which is why the unit has to be looked at by an Authorized Repair technician.

Didn't Work
The pressure washer was delivered and looked fine. I put gas in it to use it and it would not start.

When I called Pressure Washers Direct I was told because I put gas in it that it could not be returned. I was told where to bring it to be looked at and repaired. I brought this 150+lb machine to the place and was told it would be at least 2 weeks so my $900. pressure washer is at a shop being serviced.

I understand that once there is gas in it that it is not allowed to be shipped but... more

Christine,
Since there is only one Generac service location in your area they will be busy this time of year- we apologize for the inconvenience! We agree, you should be able to unpackage the pressure washer, prep according to the Owner's Manual, and start washing.

We hope you tried letting the water run before starting the engine; it clears out air in the pump (known as vapor lock); sometimes that won't let the engine turn over.

We also hope you pulled the spark plug & checked to see if oil had gotten on it during shipping. Sometimes just cleaning the plug will let the engine start. (We instruct the shippers not to tip the unit over, but sometimes it still happens...)

It is Federal Law that will not let an engine that has had gas in it be shipped, because of the fire/explosion hazard. That's why we only sell products with Factory Warranties and national service networks.

Free Shipping Plus $50
Real easy, would do business again.

Free Shipping great but $50.00 for a truck with a lift gate or have a loading dock. Just who has a loading dock at there house. Could not sit home waiting for the delivery so had to pay aditional money and hope my 110 lbs wife could handle it- she did.

Should come up with a better way to deliver or hide the extra cost. Other then the shipping extras everything was as promised and will do business in the future. Yes, would Recommend!!!

Going From 2800 Psi To 4000 Psi Saves Time
I used both the pressure washer and the surface cleaner for pavers in my driveway and pool deck. Going from a 2800 PSI washer with wand onl to this 4000 with surface cleaner, I went from 3 hours on the paver driveway to under 1 hour.

Power is awesome. I love the throttle control and PSI control knobs. I like how the pressure washer is more "upright" and not so wide and low to the ground (a smaller "footprint"). This takes up less storage room in the garage.

Good.. For The Most Part
So far it seems like a good pressure washer, however the flywheel for the pull starter broke on the second day of using it It is made out of plastic for some reason.

Besides this it is a good pressure washer but hopefully I will be able to get it fixed soon.

Love Its Power
I cleaned my fence, pavers, pool area, and Stampcrete in less time due to the power of this machine. In the past I would never have finished the job because it took too long.

It is easy to move around from job to job. It does have some vibration though so I recommend to make sure all bolts and nuts are tight, a couple of mine came loose no biggie though easy enough to tighten. I am not much on pull cords so I wish it had electric starter. For this price and machine I'll deal with pull cord.... more

Runs Perfectly
I've started this unit about a dozen times, and it starts on the 1st pull if the choke is not used. The unit ran perfectly for all of the 12 hours I have used it.

It is well balanced, & rolls with ease. The only issue is the pressure regulator: it slowly turns itself to a lower pressure if not turned fully/tight to the highest pressure. This is a manufacturing problem that needs to be solved.

Suggestion: Hose & wand are quality, thus very heavy. Wand tube is long & should be... more
