We all know how handy pressure washers can be. Apart from using stiff brushes, you can blast high-pressure jets of water at moss and oil stains on your driveway to give it a clean look.
They’re also useful for cleaning decks, windows, patio furniture, and, of course, cars and motorcycles. Pressure washers deliver upwards of three times as much force as traditional garden hoses, making them the go-to tool for heavy-duty outdoor cleaning.
This time, we’re going to compare four of Stanley’s pressure washer models – the Stanley SHP1600, the SHP1900, the SHP2000, and the Stanley SHP2150 pressure washer. These versatile units have a ton to offer – high-pressure, portability, long hoses, and they use much less water compared to many pressure washers on the market.
There are several overlapping specs between models that we’ll discuss briefly, but we’ll mainly focus on what differences they possess and how they affect overall performance and controllability.
SHP1600, SHP1900, SHP2000, and SHP2150
Gallons-per-minute (GPM) measures how much water is being expelled from the lance ever 60 seconds. Generally speaking, we want a pretty low GPM rating while still offering enough water to clean grease off of driveways, leaves off of pathways, and grime off of our cars. All four of these Stanley models have GPM ratings of 1.8, meaning you’re using much less water than you’d otherwise use with a traditional garden hose (around 7 GPM on average).
The PSI rating measures how much force the 1.8 GPM of water is being shot out of the nozzle. The higher the PSI rating, the more powerful the machine. The SHP1600 has a PSI rating of 1,600. This is, by no means, anywhere near the most powerful corded-electric pressure washers available on the market, but it’s still enough for most light- and medium-duty tasks.
When it comes to Stanley’s SHP series, the higher the model number, the greater the PSI rating is going to be. This model delivers up to 1,900 PSI, making it more powerful than the previous model and several times more powerful than a standard garden hose.
As you can probably tell by now, the SHP2000 delivers up to 2,000 PSI of water-jet force for lifting dirt, grime, grease, and all sorts of debris from your driveways and vehicles. For all-purpose outdoor cleaning, we recommend finding a model that offers at least this high a PSI rating for increased versatility.
Finally, the SHP2150 offers up to 2,150 PSI of force for picking up even the most caked-on messed from any surface. This is about the average PSI rating for high-performance residential-grade pressure washers.
Conclusion: If you’re looking for pure power, we recommend getting either the Stanley SHP2000 or the Stanley SHP2150. For most cleaning jobs, you’ll want as much pressure as possible to lift thick, slippery messes from every surface. However, if you need an electric pressure washer for general patio and car cleaning, then even the SHP1600 can do the trick.
Nozzles and Soap Dispenser
There are different nozzle designs to adjust how much pressure your device offers. For delicate surfaces like cars and windows, you won’t want to blast super-pressurized water since it can potentially cause damage. The SHP1600 comes with a twist nozzle that lets users adjust how wide to spray. A wider spray angle equals less pressure. This model comes with a 14 oz soap tank.
The nozzle on the SHP1900 is a bit different from what we’re used to seeing. Like the previous model, there are no quick-connect tips to attach to the wand. Instead, you twist the end of the wand to select between three modes – high, low, or turbo. This device features a 28 oz tank for detergents.
The 2,000 PSI model features four different quick-connect nozzle tips to attach to the wand. You get a red 0°, a green 25°, a rotary nozzle, and a black nozzle-tip made for delivering suds and bubbles. The rotating nozzle is a unique attachment that supposedly reduces cleaning time by up to 50%. This unit comes with a large 48 oz tank for liquid soap.
The SHP2150 features all four standard quick-connect nozzles that you’d normally find in a pressure washer. These are 0°, 15°, 25°, and 40°. As for spraying soap, there’s no dedicated tank for holding onto soap, but instead, you get a separate foam cannon to do the job.
Conclusion: Some might argue that changing between nozzles is a hassle, especially if there are no dedicated storage compartments for keeping the tips safe and sound. However, in our experience, they offer more versatility than you’d hope to get out of a twisty wand such as in the SHP1600 and the SHOP1900. The SHP2000’s neat rotary nozzle makes the unit stand out, though we prefer the SHP2150’s four connectors and foam cannon.
Wheels and Mobility
Corded-electric pressure washers are naturally light so carrying it around with you isn’t a big problem. However, if you plan on cleaning a large area, it’s best to purchase a model that comes with wheels. Unfortunately, the SHP1600 doesn’t feature any wheels, but it only weighs around 16 pounds so you won’t strain your back taking it from place to place.
SHP1900, SHP2000, and SHP2150
The other three models come with wheels and a tall handle, making them easy to drag around your driveway or patio. The SHP1900, SHP2000, and SHP2150 are also lightweight (25 pounds, 31 pounds, and 26 pounds, respectively) so carrying it up and down stairs shouldn’t be a tremendous issue.
Conclusion: Even though some customers might prefer a wheel-less model such as the SHP1600, we much more prefer the wheeled models – the SHP1900, SHP2000, and SHP2150. Also, their handles and lightweight-designs let you lift them up when the need arises.Related Pressure Washer Articles

Stanley Pressure Washer Comparison: Bottom Line
As we mentioned before, many of these models come with overlapping specs, making it quite difficult to pick one out of the four Stanley-made pressure washer models in this article. However, if you need a versatile, portable, and powerful device, we highly recommend going with either the Stanley SHP2000 or the SHP2150.
From personal experience, we found that the twisting motion to adjust the amount of water pressure on the Stanley SHP1600 and the SHP1900 can be tricky, but the classic quick-nozzle build of the SHP2000 and the SHP2150 is straightforward and easy to use. Furthermore, if we had to choose between the Stanley SHP2000 and the Stanley SHP2150, we’d much rather go with the latter. The tipping point is the Stanley SHP2150’s foam cannon.
