Questions & Answers


Is it a honda engine?

Asked by Brian November 22, 2020

Brian, This comes equipped with a Simpson engine. The Simpson Service team.

Can it be used with 140 degree water from hot water faucet?

Asked by TA October 28, 2020

Hi. No, this is a cold water-only pressure washer. The manual specifications indicate: Inlet Water: cold tap (100 °F max)

So I returned my last washer because the pressure unloader would not rotate per the instructions ...

Asked by Ben October 22, 2020

Ben, The unloader valves are some times over tightened at the factory during testing. You only need remove the plastic cover and loosen with a wrench

Water supply any issues keeping enough water going to it? What size hose everyone running to it as a supply?

Asked by Lester October 6, 2020

Hi there. This is not a problem. Per product manual, the inlet pressure can be: Presure of Inlet Water: 20–100 PSI @ 4 gallons per minute (+/- 10%). I run this pressure washer at its maximum 4,400 PSI output from a residential water tap, using a standard (but good, consumer quality) garden hose.

Does this unit have a variable pressure adjustment

Asked by Radar October 1, 2020

Yes it does. I never use it though.

Hi, I just received this unit. The throttle lever does not move.

Asked by Wrpt August 15, 2020

It moves, but it takes a LOT of force to move it. You'll think that you're going to bend the lever, but it will eventually slide. I thought the same thing the first time I tried to move it on mine. I didn't loosen after repeated usage's hard to move!

is a veteran discount available

Asked by tc August 14, 2020

Hi TC, please contact your local Home Depot for available veteran discounts. -SIMPSON Team

Hello, I need the ship dimensions for P60843 and 20" Surface Cleaner 80182. And the confirmation...

Asked by Acsh2792 July 1, 2020

This power washer exceeds my expectations and I am a strong believer when investing to make sure you “can’t” out grow your investment. My only disappointment is there is a small leak between the coupler connecting the hose and the wand. I have used the system 2x with same issue. “ this should have never passed a pressure test”

can anyone tell me if this 4400 Psi can run a pavement cleaner 20 in according to the one I just ...

Asked by DLM June 17, 2020

I run a 20 inch Rigid surface cleaner just fine.

Why Honda [PS60869 4000psi, 3.5gpm @ $879] costs $172 more than Honda made for Simpson [PS60843 4400psi, 4gpm @ $707.13]

Asked by Mark007 June 10, 2020

i wondered the same thing..but im pretty happy to get more power at a cheaper price than i paid for a generac 4200..

Great machine with a couple of flaws.
Customer review from logo
I've had this machine for only a week and only 1 hour and 20 minutes of run time on the hourmeter I installed, so this review is only an initial assessment. The machine is a beast and not for the frail, it's heavy, the monster hose needs to be rolled, not lassoed, and the recoil from the pressure is a good 30 pounds, so be prepared to get a good workout in. Otherwise, besides it's few flaws, I love it. I ran it at 2750 rpms on the first use to break it in and really, that's more pressure and volume than most other machines put out at full power, and at that rpm the engine sounds like it's just cruising along rather than screaming. The one major flaw is the pressure release valve installed on the pump, when you shut the machine down it sometimes squirts cold water on a very hot engine resulting in a cloud of steam and the engine complaining with all sorts of crackling sounds from the sudden and unequal contraction on one side of the cylinder wall. I solved the flaw with a rubber elbow and a stainless hose clamp, something Simpson could do for pennies. The other issue is the grab handle that goes over the engine, it doesn't fit squarely against the other handle and I had to leave it off.

Really powerful!
Customer review from logo
Brace yourself before you pull the trigger, this baby will knock you on your butt. I am able to rinse 3 story gables from the ground with just the 30” extension. My 12’ extension wand and the soap nozzle applies the solution to that height. I added a 5000 psi gauge and, sure enough, I get 4400 psi with the Simpson motor using a 100’ hose. The pull cord location is a little awkward. The entire unit wants to turn as you pull. I put my foot on the wheel to hold it still but watch that you don’t damage the valve stem like I did. I wish it had an optional battery starter, I’m in good shape and I have to pull real hard for a one-pull start. When shutting it off, bring the wand back to the machine with you because you need to pull the trigger to release pressure if it doesn’t start on the first pull. The unit is well balanced and easy to roll up a ramp into my van. This unit paid for itself with one job. Of corse it was a big place...

I have only used the machine on one job so far. But, so far I am very happy with this machine. I do some pressure washing for my lawncare customers and I'd been using my old 2400 psi 2 gpm machine that I had been using around the house. Well the pump finally gave out so it was a good time to step up a notch. This machine is powerful. I really have to hold on to the gun. The extra gpm 's really help when rinsing. It's a breeze to move around. It usually starts the first pull. It's got 50 feet of hose as opposed to 20. I have a 100 foot hose and it handles it just fine. Lots of pluses. It's only been a couple of weeks, but so far sooooo good!

Perfect Power
Customer review from logo
This pressure washer for the money your not gona find anything that comes close.It has a AAATriplex pump, which I think are the best pumps and long as you flush and use a pump saver of some sort after every use they last forever.I have a Window Cleaning and pressure wash business so I put a lot of hours on my machines.This machine is perfect cause you can adjust the pressure with the unloader valve and it also works great to bead blast stuff with.Like I said for the money this machine is the best and can pretty much do everything,just buy it! You won’t regret it,trust me,I own five of them.....
