Zoom on the Simpson PS3835
The Simpson PS3835, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and frail surfaces
- use of detergent and cleaning solutions
The Simpson PS3835's triplex pump, powered by a powerful 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.
This gas-powered pressure washer’s Honda GX270 engine is started by a traditional pull-start mechanism.
A steel fuel tank with a maximum capacity of 1.6 gallon is used to store gasoline.
Design & Handling
The wheelbarrow design of the Simpson PS3835 grants mobility and stability to the unit. The robust and sturdy welded steel frame offers longevity to the assembly. The handle adds to the PS3835 convenience of transport.
This model weighs 123 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. A key role in its final weight is played by its 270 cc Honda GX270 engine, the triplex pump and welded steel frame. However, the unit is mobile thanks to its two 13" pneumatic wheels, which add to its movability and allow it to be manipulated smoothly on the job.
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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The detergent will be added automatically to the water when a soap nozzle is attached.
- Pressure hose: The 50 ft ⌀3/8" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
- Spray gun and wand: The included classic ergonomic spray gun and its steel wand can be easily stored in a side hook.
- Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.

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 and its 3800 PSI, ranks amongst gas-powered pressure washers with a comparably low pressure output, considering the units that cost between $1000 and $1200. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Lifan LFQ4515E-CA, which reaches up to 4500 PSI.
- In its respective price range, the water flow of this washer, 3.5 GPM (gallons per minute), ranks as average. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Lifan LFQ4515E-CA, which can reach up to 4 GPM.
- The PS3835's Cleaning Units, 13300 CU (PSI x GPM), fall into the lower end when compared to gas-powered devices of similar price. If you consider the highest overall cleaning power as a really important factor, the Lifan LFQ4515E-CA and its 18000 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
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.
