Questions & Answers

Is there any container for chemicals or soap in this?

The answer is no. It does not contain a container rather, it has a siphon tube that draws directly from your supplied container. This refers to a 5 gallon container or a gallon jar.

Do the pressure settings on this washer vary?

A screwdriver is needed to adjust the uploader valve so that you can adjust pressure. The black handle looks like it is near the quick connection for the hose on the pump. If you look at the valve, you will see an arrow with a + and & You can read it in there. You can adjust the pressure by turning it.

Is surface cleaner included in the package?

I do not think so

A minimum of use leads to the failure of the device
5/5

Power washers are typically used for just a few hours at a time. I used this power washer from May 2017 to January 2018. The seller stated that there was a warranty on this machine, so when it stopped working I brought it to an authorized shop for repair. I was told that the cost of the repair would be over $350. This power washer doesn't come with a warranty since even if the company doesn't support the product, I would not suggest purchasing it.

Zero stars for packaging, five stars for performance
3/5

Choosing a good pressure washer was my main goal since this is my first pressure washer. Yes, I could have saved a little cash by getting a smaller unit, but I didn't want to have to spend all day and all weekend sweeping Thanks for the big one, I was glad to get it. Later, I will elaborate on that. I then fed the pump water after adding the included oil and filling up with fresh gasoline and pulled the recoil starter after adding the oil. I was happy to see it start right up, as Hondas do! No GPM) and immediately began clearing the scum. By the way, it is well muffled for a motor of such a large displacement. In most cases, the 50 foot hose will be more than enough, but adding a 100 footer to the accessories pile would help when cleaning off rockeries and brickwork around the backyard. This is the Evergreen State after all, where moss grows everywhere! It seems that Moss has met its match with this unit, but let's not graze on that. hose measures 3/8", is burly but not particularly clumsy, and is easy to use and clean When it comes to power, you have to pay. There is some need to deliberately lay out the hose according to your intended cleaning path to avoid loops or twists due to it being uncoilable without setting the wand down, walking back to the problem area and setting it up It's a given that this is what we do A Honda 390 pumping four gallons per minute does so with a lot of power. The wand is easy to use but care must be taken when getting too close to wood, especially with a turbo head, as it will tear it up in no time. With the regulator on the wand, it was possible to reduce the pressure and flow around delicate areas and around planters With out this machine, I would not be able to do my job. It is absolutely beautiful, and I love the aluminum frame and base. The fact that it won't rust and will be light in weight is an added plus. In terms of the CAT pump, what is not to like? Industrial duty and readily rebuildable, it is the best on the market. With pressure washers, the pump is really what makes the difference. I can also say that this unit is an overkill extreme pressure washer if you plan to use it primarily for auto or boat cleaning. The electric Karcher machine or another machine of similar scope would be ideal for your needs. This is a must have if you value your time as much as your money and want to be able to spend as much time enjoying your property as you can! In this part, I'm going to discuss Upon receiving the package at my house, the courier reported that the cardboard had already been torn and that plastic packaging film had been bandaged over the unhappy When the courier left, I noticed the frame had bent and the handle wouldn't slide on. After a preliminary inspection, nothing appeared to be wrong, but as soon as the courier left, I noticed the frame had gotten bent. Rather than patch up the post, I just bent it back into place enough to slide the handle on smoothly. We were fortunate that no damage was done to the actual engine. In fact, I have given it 5 stars because I think it deserves it, but Simpson should take a step back when it comes to its It is an outrageous mistake to ship a 1300 dollar, 125 pound appliance in a 2 dollar box made of corrugated cardboard. As it made its way to my driveway, it was essentially swimming in a paper bag. There was no extra protection provided for the wand and tube when they were dropped into the box, and that they were not damaged or damaged is nothing short of amazing. In summary, if you order one of these, you might be rolling the dice as far as damage is concerned. If a significant impact occurs, be prepared to refuse the shipment or finish up with the aftermath.

The throttle is wide open
4/5

If you purchase this pressure washer, you will find that it has no throttle control, so it will always be operating at wide open throttle! You must shut the motor off in order for the fuel to load up. As you try to restart it, it backfires and you lose the pull cord and try to start it again, ripping the pull cord out of your hand and hitting you in the chest! It seems to have a throttle control lever from the pictures and what I've read online. A false advertisement has been placed here. On top of that, it makes you seem very unprofessional at work! There is no way I would recommend this product! Neither Simpson white shipping box nor the Simpson black shipping box were used. Brown cardboard box was used for the packaging. A Simpson 4200 PSI aluminum frame with a CAT pump and red12 is shown in the picture. Powered by the mighty Honda engine, this pressure washer delivers 5 horsepower! If you are thinking of purchasing this product, I hope you find this review valuable.

If the accessories are going to be that expensive, they ought to be of better quality
3/5

It took me just one day to receive my Simpson pressure washer. My next action will be to get the machine, but first I need to get it delivered. Amazon scheduled delivery to have my package delivered. I was scheduled to meet with her on a Saturday morning from 6am to 10am 900 a. m. I used XPO Logistics as the carrier. At 715, the driver called 30 minutes in advance to let me know that he was coming. A 30am start. This heavy box was carried in by two men from my truck all the way into my garage by two men. It was a pleasure working with them. They were very professional and I would give them a 10 out of 10. Here is the machine Honda engine, Cat pump, aluminum body. I can't complain about any of those things.
There are a few things I would like to improve, 1). Why on earth would Simpson package a $1300 pressure washer in a flimsy box. What if I buy a cardboard box for 50 cents? If, for example, you wanted to send cotton balls or feather pillows, this box would be fine. 1) The wand itself. It has a nice brass quick coupling on the outside and a nice chrome finish on the inside. The inside is littered with rust pits, however. I have a ton of rust just waiting to clog my tips, not to mention that it will completely rust through in no time.
3)The I like the fact that Simpson supplies the engine oil, but they send a Simpson house brand of oil (in a strange little bag) that does not indicate its API rating. The oil could be 20 years old and not meet the specs for my brand new Honda GX390. I'm sorry, but I just checked, and it could be old oil. If I have a Simpson engine, I will replace the oil with the proper one and save the Simpson oil for starting a campfire or something like that, it will never go into my engine. This machine has not even been started yet (I need fresh gas first), but as soon as I finish it, I will update my A small update purchased a quart of Mobile 1 full synthetic 10w30 from the parts store, along with a bottle of Star Tron Enzyme fuel treatment to compensate for the alcohol in the gasoline. It took exactly one quart of oil to fill the engine. Turn the engine on, full throttle, full choke, and pull the rope to prime the fuel system before you turn it off. Once the ignition has been turned on, pull the rope one time and watch the engine start and run smoothly. It must be said, though, that this machine (ALH4240) is a beast. As soon as you pull the trigger, if you're not ready, you'll be thrown off balance by the water pressure and flow. I was able to clean my dirty driveway with ease. I am afraid it may actually be way too much machine for me. The average homeowner probably wouldn't find this powerful enough for his or her As compared to some other reviews, I had no issues with leaks of water or oil. The vibration was not an issue for me, as it was There is only one important improvement that I can see that can be made to the machine, and that is to install longer "wheelbarrow" style handles that make it easier for the operator to maneuver. As a result of the performance of the machine, I bumped it up to four stars (after initially rating it three). The accessories and packaging still need to be improved, however.
