Q: On the Simpson Megashot 3100- if i order it can i get 50 feet of hose with it?
by Peter from Connecticut on July 22, 2014

A: You can order an extension with it to make your hose 50 feet total. This will come with the necessary adapter to join the two hoses together.

25' Extension Hose

You can also purchase a separate 50 foot hose.

Q: Can I use the MTM Hydro 3.0 Turbo Tip Nozzle on the Simpson Model MSH 3125-S Washer ?
Also, where do I find a tank for the cleanser so the siphon tube can go into and does it mount to the washer ? Thanks a lot

by Pat from New Jersey on July 14, 2014

A: Yes the MTM 3.0 orifice turbo nozzle would be the correct item for you. We do not sell add on detergent tanks here. I would recommend reaching out to the folks at Simpson to see where one can be purchased. Their number is 877-362-4271
by Mike, Product Expert
Q: Does the Simpson 3100 have a container to put cleaning detergent in.
by Jason from Louisiana on March 09, 2014

A: No this unit does not have a detergent tank. It comes with a downstream injection system, which is a siphon hose running off the pump. You would put the siphon hose in a detergent of your choice and it would draw chemicals when using the black tip.
by Mike, Product Expert
Q: I bought a Simpson 3100 from Sam's that was the display model, when I got home there were no spray nozzles. I think the bag blew out of the pickup. Anyway, I need to get tips for the sprayer, a model MSV3100 p/n 60464. Are tips available separately?
by John Owens from New Mexico on August 30, 2011

A: Yes, there are definitely spray tips available for purchase. I am posting a link below to the correct size tips you would purchase for that model:

Q: I'M CONCIDERING BUYING A SIMPSON 3100 MODEL MSV3100. DON'T KNOW ANYTHING ABOUT PRESSURE WASHERS.
I'M A FARMER AND I WILL USE IT AS AN ALL AROUND PURPOSE WASHER. IS THIS A GOOD PRESSURE WASHER

by LARRY GUNTER from South Carolina on March 26, 2011

A: Simpson is one of the first and largest pressure washer manufacturers in the U.S. and they make great quality pressure washers. Also, this model has a Honda engine installed on it which is one of the most reliable small engines available for pressure washers. You can definitely use this model pressure washer as an all purpose machine that would be capable of handling a variety of tasks

Q: I have moss buildup on my concrete patio which is very thick. I need a pressure washer that will clean down to the concrete in a fairly short period of time. I've used the 2600 psi versions before but they do not cut it. Any advice?
by Robert Olsen from Washington on March 26, 2011

A: I would definitely recommend using a pressure washer with at least 3000 psi. A 3000psi pressure washer is normally sufficient for cleaning concrete. Given the amount of moss build up that you have and depending on how large of an area you have to clean, you might want to purchase a pressure washer with a psi rating between 3400-4000 psi to complete the project as fast as possible.
by Mike, Product Expert
Q: I bought a 3100 psi Simpson PW @ Sam's Club. Can I get a 50 foot hose with fittings for this machine from you/Simpson?
by Bert Solomon from South Carolina on March 26, 2011

A: Yes, we carry a 5/16" 50' hose by Legacy.

I posted a link below to the hose I am referring to:

There isn't a big stretch between our "Better" and "Best" choices in this category. Both have good engines and good pumps.

However, this Simpson unit has a durable Honda GC engine, which has earned it's place at the top of the small engine heap for being quieter and easier to start than other engines in its class.

Amongst all of the consumer grade pressure washers we carry, this model has been by far the most reliable and durable pressure washer in this category.

I Definitely Do Not Have Buyer's Remorse
I borrowed my buddy's power washer to do some home work i.e. mold and just plain cleaning and I wasn't satisfied with his 2300 PSI, 2.0 GPM because it wasn't powerful enough to clean the wood deck well.

SO, I bought this model and I AM TOTALLY SATISFIED! I was scared at first about buyer's remorse lol, but once I cranked it up and got it started, I felt like I had power in my hands!

I felt like taking it on a test run on that stubborn stain on my wood and BAM GONE. I WIN! lol.

Cannot Connect Hose To Washer
I received the washer 2 days ago. I found that I could not attach the high pressure hose to the pressure washer. It is apparently missing threads. I contacted the company and they are supposed to be sending out a replacement hose. Waiting to use.

Philip,
That is very odd... I'm glad the folks at Simpson are taking good care of you. We will follow up and make sure this is just a one-time thing, and not a bad batch of hoses. Thank you for letting us know.

We appreciate your business, and apologize for any inconvenience.

Nice Unit
Bought this to replace a similar one that I used for years and gave to my son. Very pleased with the performance and quality more than adequate for my medium duty usage.

House Clean-up
I am fixing my house to put it on the market for sale. I bought this unit because it had the bigger (1.9) Honda engine. I used it to strip the paint off my wooden front porch for repainting so far and it performed well.

Great Power Washer
This was exactly what I was looking for. Gentle enough to wash the car and powerful enough to easily clean the concrete.

My only disappointment was the soap feature. I really wanted the high pressure (or higher pressure) soap feature to quickly wash the cars. The soap nozzle disperses the soap over the car but I still have to hand wash. I guess it's for soaping with detergents that have to soak and don't require high pressure. Not a deal-breaker by any means, the correct nozzle rinsed... more

Dale,
Most pressure washers dispense soap at low pressure. Using the black tip opens the valve to the soap siphon and allows the water rushing by to draw the soap up into the water stream. Low pressure prevents driving soap deep into cracks where it would be difficult to rinse out.

If you'd like a nice layer of foam for car washing, take a look at this Detergent Foamer from MTM Hydro. The video shows how well it works washing cars quickly.

Great Machine
Takes about 15 - 20 minutes to setup. Directions are not very well laid out but you can get through it by flipping back and forth.

Machine itself is nice and beefy. Honda engine is top notch. I would recommend to anyone who is looking for a nice, powerful unit for home based projects.
Pros: Easy To Use, High Quality, I'd Buy It Again, Exceeded Expectations

Very Good For Around My Home
I have used this washer twice and still haven't finished my projects. I also have another home to do, so when I have time, I crank it up. I also really enjoy using it.

Imagine, a woman saying using a powerwasher is fun! It is !!!!.

Pressure Washer Bliss
This pressure washer does it all: dirty motorbikes, moldy decks, stained concrete. It gets the job done in less time, and everything looks great.

The different nozzles make it work awesome for each type of cleaning. I live in the forest in the Pacific Northwest, and this pressure washer is a tool I wish I had years ago.

Compact And Powerful
So far the appears to be a great p/w. Used a couple of times, ran great and was easy to start.

Only problem is the various spray nozzles, will not stay in the built in tray on the handle bar.

P/W has plenty of power.

You may want to give the folks at Simpson a call, toll-free, at 877-362-4271 to see if they have a solution to keeping the nozzles in the tray.
