This is my review of the Simpson MegaShot power washer.

Simpson MegaShot: Pros and Cons

Owning a reliable power washer is critical if you're a painter or a homeowner with exterior painting projects to tackle. The best type of pressure washer to go with is a gas-powered one, not electric. Gas models are much stronger and faster for cleaning decks and fences in my experience.

In my case, I needed to replace my Troy Bilt pressure washer that lasted many years, so I bought the Simpson MegaShot equipped with a Honda motor.

The Simpson MegaShot model I own is gas-powered and produces 3,100 PSI (pounds per square inch) and 2.5 GPM (gallons per minute). I use this power washer to clean exterior surfaces in preparation for paint and stain.

This power washer has performed great since I first bought it in 2017, but in this review, I cover both the pros and cons based on my experience using it to clean decks and fences.

Simpson MegaShot Advantages

  • Honda motor

The washer fires up on the first or second pull of the cord, every time I use it, even after sitting in the garage during cold weather. One of the reasons I chose this machine was for the quality Honda motor, which hasn't disappointed me so far.

  • Cleans well

I use this power washer mostly for paint and stain preparation (decks, siding, fencing, trim) with positive results. At 3,100 PSI, mildew stains and loose paint wash off easily at close range. The water force is very powerful. The 3,100 PSI rating is also strong enough for cleaning concrete.

  • Steel spray wand

The spray wand on my previous machine was made entirely of plastic and eventually cracked. I don't have to worry as much about damage if I accidentally drop the steel wand.

  • Kink-free hose

The hose is too short, but it doesn't kink at all. The hose is also thick enough for protection against abrasion. So far, the hose doesn't show any signs of wear.

  • Gas efficiency

The gas tank is actually a bit small, but the machine will run for about one hour on a full tank of gas. I rarely run the pump that long anyway, but you will need to refill the tank if you're running it for an extended period of time.

Simpson MegaShot Disadvantages

  • Pressure hose length

The twenty-five-foot hose on the Simpson pressure washer is horribly short and impractical for a contractor. I use the longer fifty-foot hose instead. If you plan on using the washer regularly, buying the longer fifty-foot hose is a worthwhile investment, or you'll be wheeling the machine closer to you constantly.

  • No detergent tank

While the siphon tube that Simpson includes works fine, I still prefer the convenience of a mounted detergent tank. When I use the siphon tube, I have to fasten the container to the back of the power washer with a bungee cord to keep the container from falling over from vibration. This isn't a huge deal, but detergent tanks come in handy.

  • Pull cord location

Pulling the cord is a little awkward due to the cord being positioned behind the chassis bar on the front of the machine. The decorative foam padding on the chassis becomes torn and ruined from the cord scraping it.

  • Hose inlet location

The inlet for the garden hose connection is located directly below the pressure hose inlet, which makes it difficult to unscrew the garden hose at the end of the workday. There should be more space between the two connectors.

  • Pressure hose holder

The holder for the pressure hose is small and doesn't work well with the longer fifty-foot hose. Two brackets on the holder, instead of one, would keep the hose in place better.

Is the Simpson Pressure Washer Worth the Money?

The Simpson MegaShot is a good direct drive power washer for a painter or a homeowner for the price. I recommend buying the model with the Honda motor. For my painting business, it's been a great machine for the occasional cleaning of decks, fences and siding. Most of the painting I do is interior, so spending a couple thousand dollars on a fancy power washer is overkill, but if you do a lot of pressure washing, a belt-driven pump will last longer than a direct drive model like this one.

The main disadvantages I have encountered are mostly minor design flaws like the weird location of the pull cord and water inlet connector. A separate detergent tank would be nice, but the siphon tube works well too. Once the tube is connected to the pump, using the black cleaning tip automatically siphons the cleaner through the machine for cleaning. When you're done cleaning, simply disconnect the siphon hose and remove the cleaner tip.

Most importantly, though, the washing capability is very good for cleaning wood and concrete. The Honda motor always starts when I pull the cord. The MegaShot comes with five spray tips and a siphon tube, not a tank, for detergent. The power washer is almost ready to go out of the box, with the exception of adding the provided oil and assembling the top frame, which is self-explanatory. The weight of the machine also isn't too heavy. I can easily lift this pressure washer into my pickup truck without hurting my back.
