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 or high reach areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted or delicate surfaces
  • applying detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

With an impressive 270 cc (9 hp) engine, its triplex pump delivers a pressure of 3800 PSI (roughly 63 times more than a standard garden hose) and a flow of up to 3.5 GPM (CETA-certified values), resulting in the Simpson PS3835's cleaning power of 13300 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GX270 engine.

Gasoline is stored in a steel fuel tank with a maximum capacity of 1.6 gallon.

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, 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 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • 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 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

  • Considering its water flow, this washer, with a GPM (gallons per minute) of 3.5 is in the average compared to other devices in its price range. 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 Lifan LFQ4515E-CA, with 4 GPM.
  • The 13300 Cleaning Units (PSI x GPM), of the PS3835 sit at an average, in reference to other gas-powered units of similar price. When it comes to the highest overall cleaning power in the current price range, one of the products at the very top currently is the Lifan LFQ4515E-CA and its 18000 Cleaning Units.
