Description

Built for cleaning professionals, the SIMPSON PowerShot 3800 PSI @ 3.5 GPM is built to perform. With a powerful Honda engine, reliable triplex pump and welded steel frame construction, this gas pressure washer is great for construction, equipment upkeep, facility & fleet maintenance cleaning.

Zoom on the Simpson PS3835

In a nutshell, the Simpson PS3835 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • 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 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.

The Honda GX270 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

Gasoline storage is facilitated by 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 welded steel frame guarantees longevity of 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. The major reasons for its heavy weight are its 270 cc Honda GX270 engine, the triplex pump and welded steel frame. However, the unit is manipulated smoothly thanks to its two 13" pneumatic wheels, which play a key role in its maneuverability.

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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: Using a set of convenient hooks, the included 50 ft ⌀3/8" high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its steel wand.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
