Zoom on the Simpson PS3835

The Simpson PS3835 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, unpainted surfaces and high-reach cleaning
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted or delicate surfaces
  • application of detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

The Simpson PS3835's triplex pump, powered by an impressive 270 cc (9 hp) engine, can provide a pressure of up to 3800 PSI (approximately 63 times more than a standard garden hose) and a flow of up to 3.5 GPM (CETA-certified values). The Simpson PS3835 thus has a cleaning power of 13300 Cleaning Units.

The Honda GX270 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

The fuel is stored in a steel tank, which can hold up to 1.6 gallon of gasoline.

Design & Handling

The wheelbarrow design of the Simpson PS3835 grants mobility and stability to the unit. The robust welded steel frame guarantees longevity of the assembly. The handle adds to the PS3835 convenience of transport.

With a weight of 123 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. The main contributor to its weight are its 270 cc Honda GX270 engine, the triplex pump and welded steel frame. However, its two 13" pneumatic wheels play an important part in its maneuvrability, as they allow for a smooth manipulation on the job.

Main Features

The Simpson PS3835's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The detergent will be added automatically to the water when a soap nozzle is attached.
  • Pressure hose: A neat storage for the included 50 ft ⌀3/8" high-pressure hose is facilitated by a set of convenient hooks.
  • Spray gun and wand: Both the classic ergonomic spray gun and its steel wand may be conveniently stored in a side hook.
  • Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.

The Simpson PS3835's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Simpson PS3835 compare to similarly priced pressure washers.

  • The Simpson PS3835 with its 3800 PSI achieves a lower pressure value, compared to other gas-powered pressure washers in the $900-1000 price range. If you're going after the highest possible power of the water stream, one of the best in this price range is the Lifan LFQ4515E-CA that can reach up to 4500 PSI.
  • When compared to devices in the above-mentioned price range, this washer and its 3.5 GPM (gallons per minute), is on the lower end of the achievable water flow. If being able to rinse away debris as efficiently as possible is your priority, one of the products with the highest GPM in this price range is the Predator 4400, with 4.2 GPM.
  • The PS3835 ranks as below average in terms of Cleaning Units, compared to gas-powered devices in its price range, reaching only a value of 13300 CU (PSI x GPM). If you consider the highest overall cleaning power as a really important factor, the Predator 4400 and its 18480 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.

Price comparison

As you can see from this interactive chart, when compared to other gas-powered washers between 12500 and 14000 Cleaning Units, the Simpson PS3835 is on the average side of the price range.

Therefore, this pressure washer nicely fits in the expected budget for this kind of cleaning power.
