Customer Questions & Answers

Can I use hot water with this product

Asked by: Jimbo
As I recall, the instruction manual says NOT to use hot water. The engine uses the water passing through the pump as a way to stay cool. I suspect that running hot water through it would defeat that ability and the motor would overheat. By the way, when the motor overheats, which can happen if you stop spraying for too many minutes while the motor is running, a relief valve opens on the side of the pump and water runs out.

You may have to ask your own Home Depot. The store I used did not honor that type of discount.

what is the hose made of

what is the hose made of
Asked by: cody
The hose is made from a special highly flexible inner core then a polyester reinforcement then a poly urethane outer cover for the best abrasion resistance to tough surfaces. The outer core is great for wiping it down to get any dirt or grime off quickly after pressure washing and putting up for storage. Will not mare or mark the surfaces as well. Great Hose but keep away from the muffler.

CAN U USE DETERGENT WITH THIS IS THAT WHAT A DETERGENT WAND IS FOR

Asked by: WIFE
Yes you can use detergent. It comes with a hose you connect to the unit and place in the detergent. I like that there is not a detergent reservoir. I can use several different detergents without dumping/emptying the reservoir on units that have attached containers. The containers inevitably get clogged and are more of a hassle than convenience.

WHAT IS REQUIRED FOR WINTER STORAGE

CAN'T FIND MANUAL
Asked by: SOXXY
I put some Stabil fuel stabilizer into the gas tank and then run it for my last Fall chores. After that I syphon out the fuel and run it out of gasoline (until it quits). Oh, and I store it in the basement.

Can I hook up two hoses together to reach if I want to get on the roof?

Can I hook up two hoses together to reach if I want to get on the roof?
Asked by: Isma
It is much better to use a longer high pressure hose instead to connect two hoses together for safety and to keep the pressure equal inside the hose.

MegaShot 3,100 psi 2.5 GPM Gas Pressure Washer Powered by Honda is rated 4.4 out of 5 by 773.

This was to replace a very old Craftsman washer and I have used it to wash our driveway. Came in perfect condition, was easy to set up and after filling with oil, gas and hooking up water it started on 4th. pull. I used it over a two day period and after the initial start up normally started on first pull. Pros: Easy set up Easy start Quick connect tips Great cleaning power Cons: If gas tank is filled up into the neck it vibrates some gas out, which on a wet drive will look a lot like oil coming out of the unit. After I realized what was happening, I made sure not to fill as full afterwards and that resolves the problem of gas vibrating out of the gas tank.

Rated 2 out of 5 by from Maybe Works fine. HOWEVER, I have a puddle of oil underneath every time I use it. Called Simpson, their rep said it's Honda's problem. Waited on hold until call dropped. Re-contacted them via email. No response. That's a problem. Busy at work, so haven't dogged them any further, BUT, should I have to? [This review was collected as part of a promotion.]

Rated 1 out of 5 by from Problems in less than 30 days !! Had high hopes for this unit.....put oil in, bought quick connects, fresh gas, and started up on 2nd pull ! Cleaned driveway, sidewalks and patio. Some observations: did a good job in cleaning; excessive vibration, likes to walk around a lot. Big negatives: backfires thru muffler at shutdown; leaks oil, checked bolts...were tight. I think it was pump oil. Returned to HD on the 29th day and ordered a Generac 6602. I did not want to risk running the gauntlet with Simpson CS. It costs too much to risk something that may not perform. Ordered a Generac. I know the Simpson was a lemon. Hope the 6602 works out better. These days, you pay your money and take your chances !!

Rated 5 out of 5 by from Must buy for homeowner!! First of all, I did enough research to cause my brain to ooze from my skull, and when I finally decided to go for this guy, I still had my doubts. But I have to say it's surpassed any expectation I had of it to get the job done. It's already been worth the money and it's super easy to operate. The Honda motor was a big selling point for me, and it too does not disappoint. One pull and the motor gets to work right away. Not stalling, nada. It's a beast, clean look, and very powerful. It cleaned my deck, sidewalk, and garage floor with ease. I actually look for stuff to clean just to use it!!! Awesome pressure washer!! [This review was collected as part of a promotion.]

Setup was easy and straightforward. Installed the handle, filled with oil, assembled the parts, and started the engine. The engine took about 5 to 6 pulls before it started. Once started, the engine performed well. The unit is easy to maneuver but there is a fair amount of vibration; so much so that the unit tends to "walk" and the extra spray heads fell out of their holders. Be sure to remove the spray heads and store them in a secure place before starting the engine. With the exception of the vibration; the unit performed flawlessly.

Rated 4 out of 5 by from Cautiously Optimistic... Beyond question, the Honda engine is seriously terrific. Now comes attaching an injection pump to a great engine and putting it on a frame that works. Two negatives for me - 1) Thermal relief valve - why should someone design a system that only allows for two minutes of idle power washing time. Beyond that the valve may not close properly - mine didn't. 2) stupid, yet important. The nozzles vibrate lose and end up on the ground during any extended use. Come on, you can't design for a better press fit arrangement where the nozzles sit when not in use? [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Nice Unit Nice unit...easy put together right out of the box. Original unit damaged when assembled by what appears to be Home Depot before shipment (they apparently get Simpson part and Honda engine and assemble themselves so as to sell at best price on market). Phoning Customer Service at 7:30 Friday evening was excellent with reshipping a new unit, many apologies and a slight discount (brought original one to store next day and got refund). Unit appears top notch (spray tips can vibrate out of their nifty little holder...beware) and with a nice Honda engine I anticipate it will last quite some years with light homeowner use as a Honda engine on a 20 year old generator is still going strong. Well done Home Depot on internet ordering and customer service.

Rated 5 out of 5 by from Awsome machine I have always rented power pressure washers but this time I was reading reviews and found the Simpson MSH3125-S was the best of the best for 2016 so I was sold, I purchased machine and it is DO IT ALL machine, I can clean decks, concrete, trucks and work equipment and it doesn't let me down. I would encourage Simpson to offer a 50 foot hose as the 25 foot hose seems too short at work sites BUT machine is lite enough to carry or roll to project to use 25 foot hose [This review was collected as part of a promotion.]
